False Beliefs about Human Genes

Carl Zimmer writes at Skeptical Inquirer Seven Big Misconceptions About Heredity. Excerpts in italics with my bolds

It’s been seven decades since scientists demonstrated that DNA is the molecule of heredity. Since then, a steady stream of books, news programs, and episodes of CSI have made us comfortable with the notion that each of our cells contains three billion base pairs of DNA, which we inherited from our parents. But we’ve gotten comfortable without actually knowing much at all about our own genomes.

If you want to get your entire genome sequenced—all three billion base pairs in your DNA—a company called Dante Labs will do it for $699. You don’t need whole genome sequencing to learn a lot about your genes, however. The 20,000 genes that encode our proteins make up less than 2 percent of the human genome. That fraction of the genome—the “exome”—can be yours for just a few hundred dollars. The cheapest insights come from “genotyping”—in which scientists survey around a million spots in the genome known to vary a lot among people. Genotyping—offered by companies such as 23andMe and Ancestry—is typically available for under a hundred dollars.

Thanks to these falling prices, the number of people who are getting a glimpse at their own genes is skyrocketing. By 2019, over twenty-five million worldwide had gotten genotyped or had their DNA sequenced. At its current pace, the total may reach 100 million by 2020.

There’s a lot we can learn about ourselves in these test results. But there’s also a huge opportunity to draw the wrong lessons.

Many people have misconceptions about heredity—how we are connected to our ancestors and how our inheritance from them shapes us. Rather than dispelling those misconceptions, our growing fascination with our DNA may only intensify them. A number of scientists have warned of a new threat they call “genetic astrology.” It’s vitally important to fight these misconceptions about heredity, just as we must fight misconceptions about other fields of science, such as global warming, vaccines, and evolution. Here are just a few examples.

Misconception #1: Finding a Special Ancestor Makes You Special

You can join the Order of the Crown of Charlemagne if you can prove that the Holy Roman Emperor is your ancestor. It’s a thrill to discover we have a genealogical link to someone famous—perhaps because that link seems to make us special, too.

But that’s an illusion. I could join the Mayflower Society, for example, because I’m descended from a servant aboard the ship named John Howland. Howland’s one claim to fame is that he fell out of the Mayflower. Fortunately for me, he got fished out of the water and reached Massachusetts. But I’m not the only fortunate one; by one estimate, there are two million people who descend from him alone.

Mathematicians have analyzed the structure of family trees, and they’ve found that the further back in time you go, the more descendants people had. (This is only true of people who have any living descendants at all, it should be noted.) This finding has an astonishing implication. Since we know Charlemagne has living descendants (thank you, Order of the Crown!), he is likely the ancestor of every living person of European descent.

Misconception #2: You Are Connected to All Your Ancestors by DNA

But genetics do not equal genealogy. It turns out that practically none of the Europeans who descend from Charlemagne inherited any of his DNA. All humans, in fact, have no genetic link to most of their direct ancestors.

The reason for this disconnect is the way that DNA gets passed down from one generation to the next. Every egg or sperm randomly ends up with one copy of each chromosome, coming either from a person’s mother or father. As a result, we inherit about a quarter of our DNA from each grandparent—but only on average.

If you go back a few generations more, that contribution can drop all the way to zero. . . While it is true that you inherit your DNA from your ancestors, that DNA is only a tiny sampling of the genes in your family tree.

Even without a genetic link, though, your ancestors remain your ancestors. They did indeed help shape who you are—not by giving you a gene for some particular trait, but by raising their own children, who then raised their own children in turn, passing down a cultural inheritance along with a genetic one.

Misconception #3: Ancestry Tests Are as Reliable as Medical Tests

Millions of people are getting ancestry reports based on their DNA. My own report informs me that I’m 43 percent Ashkenazi Jewish, 25 percent Northwestern European, 23 percent South/Central European, 6 percent Southwestern European, and 2.2 percent North Slavic. Those percentages sound impressive, even definitive. It’s easy to conclude that ancestry reports are as reliable as stepping on a scale at the doctor’s office to get your height and weight measured.

That is a mistake, and one that can cause a lot of heartbreak. To estimate ancestry, researchers compare each customer to a database of thousands of people from around the world. . . They can identify stretches of DNA that are likely to have originated in a particular part of the world. While some matches are clear-cut, others are less so. As a result, ancestry estimates always have margins of error—which often go missing in the reports customers get.

These estimates are going to get better with time, but there’s a fundamental limit to what they can tell us about our ancestry. . . Researchers are getting glimpses of those older peoples by retrieving DNA from ancient skeletons. And they’re finding that our genetic history is far more tumultuous than previously thought. Time and again, researchers find that the people who have lived in a given place in recent centuries have little genetic connection to the people who lived there thousands of years ago. All over the world, populations have expanded and migrated, coming into contact with other populations. . . If you want to find purity in your ancestry, you’re on a fool’s errand.

Misconception #4: There’s a Gene for Every Trait You Inherit

Mendel is a great place to start learning about heredity but a bad place to stop. There are some traits that are determined by a single gene. Whether Mendel’s peas were smooth or wrinkled was determined by a gene called SBEI. Whether people develop sickle cell anemia or not comes down to a single gene called HBB. But many traits do not follow this so-called Mendelian pattern—even ones that we may have been told in school are Mendelian.

Consider your ear lobes. For decades, teachers taught that they could either hang free or be attached to the side of our heads. The sort of ear lobes you had was a Mendelian trait, determined by a single gene. In fact, our ear lobes typically fall somewhere between the two extremes of strongly attached to fully free. In 2017, a team of researchers compared the ear lobes of over 74,000 people to their DNA. They looked for genetic variants that were common in people at either end of the ear-lobe spectrum. They pinpointed forty-nine genes that appear to play a role in determining how attached they are to our heads. There well may be more waiting to be discovered.

The genetics of ear lobes is actually very simple compared to other traits. Studying height, for example, scientists have identified thousands of genetic variants that appear to play a role. The same holds true for our risk of developing diabetes, heart disease, and other common disorders. We can’t expect to find a single gene in our DNA tests that determines whether we’ll die of a heart attack. Nor should we expect easy fixes for such complex diseases by repairing single genes.

Misconception #5: The Genes You Inherit Explain Exactly Who You Are

Take, for example, a recent study on how long people stay in school. Researchers examined DNA from 1.1 million people and found over 1,200 genetic variants that were unusually common either in people who left school early or in people who went on to college or graduate school. They then used the genetic differences in their subjects to come up with a predictive score, which they then tried out on another group of subjects. They found that in the highest-scoring 20 percent of these subjects, 57 percent finished college. In the lowest-scoring 20 percent, only 12 percent did.

But these results don’t mean that how long you stayed in school was determined before birth by your genes. Getting your children’s DNA tested won’t tell you if you should save up money for college tuition or not. Plenty of people in the educational attainment study who got high genetic scores dropped out of high school. Plenty of people who got low scores went on to get PhDs. And many more got an average amount of education in between those extremes. For any individual, these genetic scores make predictions that are barely better than guessing at random.

This confusing state of affairs is the result of how genes and the environment interact. Scientists call a trait such as how long people stay in school “moderately heritable.” In other words, a modest amount of the variation in education attainment is due to genetic variation. Lots of other factors also matter, too—the neighborhoods where people live, the quality of their schools, the stability of their family life, their income, and so on. What’s more, a gene that may have an influence on how long people stay in school in one environment may have no influence at all in another.

Misconception #6: You Have One Genome

According to this assumption, you will find an identical sequence of DNA in any cell you examine. But there are many ways in which we can end up with different genomes within our bodies.

Fairchild is known as a chimera. She developed inside her mother alongside a fraternal twin. That twin embryo died in the womb, but not before exchanging cells with Fairchild. Now her body was made up of two populations of cells, each of which multiplied and developed into different tissues. In Fairchild’s case, her blood arose from one population, while her eggs arose from another.

It’s unclear how many people are chimeras. Once they were considered bizarre rarities. Scientists became aware of them only in cases such as Lydia Fairchild’s, when their mixed identity made itself known. In recent years, researchers have been carrying out small-scale surveys that suggest that perhaps a few percent of twins are chimeras, but the true number could be higher. As for chimeric mothers, they may be the rule rather than the exception. In a 2017 study, researchers studied brain tumors taken from women who had sons. Eighty percent of them had Y-chromosome-bearing cells in their tumors.

Chimerism is not the only way we can end up with different genomes. Every time a cell in our body divides, there’s a tiny chance that one of the daughter cells may gain a mutation. At first, these new aberrations—called somatic mutations—seemed important only for cancer. But that view has changed as new genome-sequencing technologies have made it possible for scientists to study somatic mutations in many healthy tissues. It now turns out that every person’s body is a mosaic, made up of populations of cells with many different mutations.
Misconception #7: Genes Don’t Matter Because of Epigenetics

The notion that our genes are our destiny can trigger an equally false backlash: that genes don’t matter at all. And very often, those who push against the importance of genetics invoke a younger, more tantalizing field of research: epigenetics.

Our cells use many layers of control to make proper use of their genes. They can quickly turn some genes on and off in response to quick changes in their environment. But they can also silence genes for life. Women, for example, have two copies of the X chromosome, but in early development, each of their cells produces a swarm of RNA molecules and proteins that clamp down on one copy. The cell then only uses the other X chromosome. And if the cell divides, its daughter cells will silence the same copy again.

One of the most tantalizing possibilities scientists are now exploring is whether certain epigenetic “marks” can be inherited not just by daughter cells but by daughters—and sons. If people experience trauma in their lives and it leaves an epigenetic mark on their genes, for example, can they pass down those marks to future generations?

If you’re a plant, the answer is definitely yes. Plants that endure droughts or attacks by insects can reprogram their seeds, and these epigenetic changes can get carried down several generations. The evidence from animals is, for now, still a mixed bag. . . But skeptics have questioned how epigenetics can transmit these traits through the generations, suggesting that the results are just statistical flukes. That hasn’t stopped a cottage industry of epigenetic self-help from springing up. You can join epigenetic yoga classes to rewrite your epigenetic marks or go to epigenetic psychotherapy sessions to overcome the epigenetic legacy you inherited from your grandparents.

Land and Sea Temps: April Southern Exposure

banner-blog

With apologies to Paul Revere, this post is on the lookout for cooler weather with an eye on both the Land and the Sea.  UAH has updated their tlt (temperatures in lower troposphere) dataset for April.   Previously I have done posts on their reading of ocean air temps as a prelude to updated records from HADSST3. This month also has a separate graph of land air temps because the comparisons and contrasts are interesting as we contemplate possible cooling in coming months and years.

Presently sea surface temperatures (SST) are the best available indicator of heat content gained or lost from earth’s climate system.  Enthalpy is the thermodynamic term for total heat content in a system, and humidity differences in air parcels affect enthalpy.  Measuring water temperature directly avoids distorted impressions from air measurements.  In addition, ocean covers 71% of the planet surface and thus dominates surface temperature estimates.  Eventually we will likely have reliable means of recording water temperatures at depth.

Recently, Dr. Ole Humlum reported from his research that air temperatures lag 2-3 months behind changes in SST.  He also observed that changes in CO2 atmospheric concentrations lag behind SST by 11-12 months.  This latter point is addressed in a previous post Who to Blame for Rising CO2?

The April update to HadSST3 will hopefully appear later this month (March is yet to be posted).  In the meantime we can look at lower troposphere temperatures (TLT) from UAHv6 which are already posted for April. The temperature record is derived from microwave sounding units (MSU) on board satellites like the one pictured above. This month also involved a change in UAH processing of satellite drift corrections, including dropping one platform which can no longer be corrected. The graphs below are taken from the new and current dataset.

The UAH dataset includes temperature results for air above the oceans, and thus should be most comparable to the SSTs. There is the additional feature that ocean air temps avoid Urban Heat Islands (UHI).  The graph below shows monthly anomalies for ocean temps since January 2015.

Click on image to enlarge.

April ocean air temps rose in all regions, putting them back comparable with January 2019.  NH warming was slight, while stronger warming in SH and the Tropics pulled up the Global average.  The temps this April are warmer than 2018, nearly matching 2017, and of course much lower than 2016.

Land Air Temperatures Tracking Downward in Seesaw Pattern

We sometimes overlook that in climate temperature records, while the oceans are measured directly with SSTs, land temps are measured only indirectly.  The land temperature records at surface stations record air temps at 2 meters above ground.  UAH gives tlt anomalies for air over land separately from ocean air temps.  The graph updated for April is below.

The greater volatility of the Land temperatures was evident earlier, but has calmed down recently. Also the  NH dominates, having twice as much land area as SH.  Note how global peaks mirror NH peaks.  In January 2019 all Land air temps were close but have now diverged.  In April both SH and the Tropics warmed (comparable to ocean temps), but the much larger NH land surface cooled, pulling the Global anomaly down.  The Tropical land air temps could not be more different from a year ago, yet the Global is about the same.

TLTs include mixing above the oceans and probably some influence from nearby more volatile land temps.  Clearly NH and Global land temps have been dropping in a seesaw pattern, now more than 1C lower than the peak in 2016.  TLT measures started the recent cooling later than SSTs from HadSST3, but are now showing the same pattern.  It seems obvious that despite the three El Ninos, their warming has not persisted, and without them it would probably have cooled since 1995.  Of course, the future has not yet been written.

 

The Poisonous Tree of Climate Change

This post was triggered by noticing an event in April that had escaped my attention.  It seems that serial valve turner Ken Ward was granted a new trial by the Washington State Court of Appeals, and he is allowed to present a “necessity defense.”  This astonishingly bad ruling is reported approvingly by Kelsey Skaggs at Pacific Standard Why the Necessity Defense is Critical to the Climate Struggle. Excerpt below with my bolds.

A climate activist who was convicted after turning off an oil pipeline won the right in April to argue in a new trial that his actions were justified. The Washington State Court of Appeals ruled that Ken Ward will be permitted to explain to a jury that, while he did illegally stop the flow of tar sands oil from Canada into the United States, his action was necessary to slow catastrophic climate change.

The Skaggs article goes on to cloak energy vandalism with the history of civil disobedience against actual mistreatment and harm.  Nowhere is it recognized that the brouhaha over climate change concerns future imaginary harm.  How could lawyers and judges get this so wrong?  It can only happen when an erroneous legal precedent can be cited to spread a poison in the public square.  So I went searching for the tree producing all of this poisonous fruit. The full text of the April 8, 2019, ruling is here.

A paper at Stanford Law School (where else?) provides a good history of the necessity defense as related to climate change activism The Climate Necessity Defense: Proof and Judicial Error in Climate Protest Cases Excerpts in italics with my bolds.

My perusal of the text led me to the section where the merits are presented.

The typical climate necessity argument is straightforward. The ongoing effects of climate change are not only imminent, they are currently occurring; civil disobedience has been proven to contribute to the mitigation of these harms, and our political and legal systems have proven uniquely ill-equipped to deal with the climate crisis, thus creating the necessity of breaking the law to address it. As opposed to many classic political necessity defendants, such as anti-nuclear power protesters, climate activists can point to the existing (rather than speculative) nature of the targeted harm and can make a more compelling case that their protest activity (for example, blocking fossil fuel extraction) actually prevents some quantum of harm produced by global warming. pg.78

What?  On what evidence is such confidence based?  Later on (page 80), comes this:

Second, courts’ focus on the politics of climate change distracts from the scientific issues involved in climate necessity cases. There may well be political disagreement over the realities and effects of climate change, but there is little scientific disagreement, as the Supreme Court has noted.131

131 Massachusetts v. E.P.A., 549 U.S. 497, 499 (2007) (“The harms associated with climate change are serious and well recognized . . . [T]he relevant science and a strong consensus among qualified experts indicate that global warming threatens, inter alia, a precipitate rise in sea levels by the end of the century, severe and irreversible changes to natural ecosystems, a significant reduction in water storage in winter snowpack in mountainous regions with direct and important economic consequences, and an increase in the spread of disease and the ferocity of weather events.”).

The roots of this poisonous tree are found in citing the famous Massachusetts v. E.P.A. (2007) case decided by a 5-4 opinion of Supreme Court justices (consensus rate: 56%).  But let’s see in what context lies that reference and whether it is a quotation from a source or an issue addressed by the court.  The majority opinion was written by Justice Stevens, with dissenting opinions from Chief Justice Roberts and Justice Scalia.  All these documents are available at sureme.justia.com Massachusetts v. EPA, 549 U.S. 497 (2007)

From the Majority Opinion:

A well-documented rise in global temperatures has coincided with a significant increase in the concentration of carbon dioxide in the atmosphere. Respected scientists believe the two trends are related. For when carbon dioxide is released into the atmosphere, it acts like the ceiling of a greenhouse, trapping solar energy and retarding the escape of reflected heat. It is therefore a species—the most important species—of a “greenhouse gas.” Source: National Research Council:

National Research Council 2001 report titled Climate Change: An Analysis of Some Key Questions (NRC Report), which, drawing heavily on the 1995 IPCC report, concluded that “[g]reenhouse gases are accumulating in Earth’s atmosphere as a result of human activities, causing surface air temperatures and subsurface ocean temperatures to rise. Temperatures are, in fact, rising.” NRC Report 1.

Calling global warming “the most pressing environmental challenge of our time,”[Footnote 1] a group of States,[Footnote 2] local governments,[Footnote 3] and private organizations,[Footnote 4] alleged in a petition for certiorari that the Environmental Protection Agency (EPA) has abdicated its responsibility under the Clean Air Act to regulate the emissions of four greenhouse gases, including carbon dioxide.  Specifically, petitioners asked us to answer two questions concerning the meaning of §202(a)(1) of the Act: whether EPA has the statutory authority to regulate greenhouse gas emissions from new motor vehicles; and if so, whether its stated reasons for refusing to do so are consistent with the statute.

EPA reasoned that climate change had its own “political history”: Congress designed the original Clean Air Act to address local air pollutants rather than a substance that “is fairly consistent in its concentration throughout the world’s atmosphere,” 68 Fed. Reg. 52927 (emphasis added); declined in 1990 to enact proposed amendments to force EPA to set carbon dioxide emission standards for motor vehicles, ibid. (citing H. R. 5966, 101st Cong., 2d Sess. (1990)); and addressed global climate change in other legislation, 68 Fed. Reg. 52927. Because of this political history, and because imposing emission limitations on greenhouse gases would have even greater economic and political repercussions than regulating tobacco, EPA was persuaded that it lacked the power to do so. Id., at 52928. In essence, EPA concluded that climate change was so important that unless Congress spoke with exacting specificity, it could not have meant the agency to address it.

Having reached that conclusion, EPA believed it followed that greenhouse gases cannot be “air pollutants” within the meaning of the Act. See ibid. (“It follows from this conclusion, that [greenhouse gases], as such, are not air pollutants under the [Clean Air Act’s] regulatory provisions …”).

Even assuming that it had authority over greenhouse gases, EPA explained in detail why it would refuse to exercise that authority. The agency began by recognizing that the concentration of greenhouse gases has dramatically increased as a result of human activities, and acknowledged the attendant increase in global surface air temperatures. Id., at 52930. EPA nevertheless gave controlling importance to the NRC Report’s statement that a causal link between the two “ ‘cannot be unequivocally established.’ ” Ibid. (quoting NRC Report 17). Given that residual uncertainty, EPA concluded that regulating greenhouse gas emissions would be unwise. 68 Fed. Reg. 52930.

The harms associated with climate change are serious and well recognized. Indeed, the NRC Report itself—which EPA regards as an “objective and independent assessment of the relevant science,” 68 Fed. Reg. 52930—identifies a number of environmental changes that have already inflicted significant harms, including “the global retreat of mountain glaciers, reduction in snow-cover extent, the earlier spring melting of rivers and lakes, [and] the accelerated rate of rise of sea levels during the 20th century relative to the past few thousand years … .” NRC Report 16.

In sum—at least according to petitioners’ uncontested affidavits—the rise in sea levels associated with global warming has already harmed and will continue to harm Massachusetts. The risk of catastrophic harm, though remote, is nevertheless real. That risk would be reduced to some extent if petitioners received the relief they seek. We therefore hold that petitioners have standing to challenge the EPA’s denial of their rulemaking petition.[Footnote 24]

In short, EPA has offered no reasoned explanation for its refusal to decide whether greenhouse gases cause or contribute to climate change. Its action was therefore “arbitrary, capricious, … or otherwise not in accordance with law.” 42 U. S. C. §7607(d)(9)(A). We need not and do not reach the question whether on remand EPA must make an endangerment finding, or whether policy concerns can inform EPA’s actions in the event that it makes such a finding. Cf. Chevron U. S. A. Inc. v. Natural Resources Defense Council, Inc., 467 U. S. 837, 843–844 (1984). We hold only that EPA must ground its reasons for action or inaction in the statute.

My Comment: Note that the citations of scientific proof were uncontested assertions by petitioners.  Note also that the majority did not rule that EPA must make an endangerment finding:  “We hold only that EPA must ground its reasons for action or inaction in the statute.”

From the Minority Dissenting Opinion

It is not at all clear how the Court’s “special solicitude” for Massachusetts plays out in the standing analysis, except as an implicit concession that petitioners cannot establish standing on traditional terms. But the status of Massachusetts as a State cannot compensate for petitioners’ failure to demonstrate injury in fact, causation, and redressability.

When the Court actually applies the three-part test, it focuses, as did the dissent below, see 415 F. 3d 50, 64 (CADC 2005) (opinion of Tatel, J.), on the State’s asserted loss of coastal land as the injury in fact. If petitioners rely on loss of land as the Article III injury, however, they must ground the rest of the standing analysis in that specific injury. That alleged injury must be “concrete and particularized,” Defenders of Wildlife, 504 U. S., at 560, and “distinct and palpable,” Allen, 468 U. S., at 751 (internal quotation marks omitted). Central to this concept of “particularized” injury is the requirement that a plaintiff be affected in a “personal and individual way,” Defenders of Wildlife, 504 U. S., at 560, n. 1, and seek relief that “directly and tangibly benefits him” in a manner distinct from its impact on “the public at large,” id., at 573–574. Without “particularized injury, there can be no confidence of ‘a real need to exercise the power of judicial review’ or that relief can be framed ‘no broader than required by the precise facts to which the court’s ruling would be applied.’ ” Warth v. Seldin, 422 U. S. 490, 508 (1975) (quoting Schlesinger v. Reservists Comm. to Stop the War, 418 U. S. 208, 221–222 (1974)).

The very concept of global warming seems inconsistent with this particularization requirement. Global warming is a phenomenon “harmful to humanity at large,” 415 F. 3d, at 60 (Sentelle, J., dissenting in part and concurring in judgment), and the redress petitioners seek is focused no more on them than on the public generally—it is literally to change the atmosphere around the world.

If petitioners’ particularized injury is loss of coastal land, it is also that injury that must be “actual or imminent, not conjectural or hypothetical,” Defenders of Wildlife, supra, at 560 (internal quotation marks omitted), “real and immediate,” Los Angeles v. Lyons, 461 U. S. 95, 102 (1983) (internal quotation marks omitted), and “certainly impending,” Whitmore v. Arkansas, 495 U. S. 149, 158 (1990) (internal quotation marks omitted).

As to “actual” injury, the Court observes that “global sea levels rose somewhere between 10 and 20 centimeters over the 20th century as a result of global warming” and that “[t]hese rising seas have already begun to swallow Massachusetts’ coastal land.” Ante, at 19. But none of petitioners’ declarations supports that connection. One declaration states that “a rise in sea level due to climate change is occurring on the coast of Massachusetts, in the metropolitan Boston area,” but there is no elaboration. Petitioners’ Standing Appendix in No. 03–1361, etc. (CADC), p. 196 (Stdg. App.). And the declarant goes on to identify a “significan[t]” non-global-warming cause of Boston’s rising sea level: land subsidence. Id., at 197; see also id., at 216. Thus, aside from a single conclusory statement, there is nothing in petitioners’ 43 standing declarations and accompanying exhibits to support an inference of actual loss of Massachusetts coastal land from 20th century global sea level increases. It is pure conjecture.

The Court ignores the complexities of global warming, and does so by now disregarding the “particularized” injury it relied on in step one, and using the dire nature of global warming itself as a bootstrap for finding causation and redressability.

Petitioners are never able to trace their alleged injuries back through this complex web to the fractional amount of global emissions that might have been limited with EPA standards. In light of the bit-part domestic new motor vehicle greenhouse gas emissions have played in what petitioners describe as a 150-year global phenomenon, and the myriad additional factors bearing on petitioners’ alleged injury—the loss of Massachusetts coastal land—the connection is far too speculative to establish causation.

From Justice Scalia’s Dissenting Opinion

Even on the Court’s own terms, however, the same conclusion follows. As mentioned above, the Court gives EPA the option of determining that the science is too uncertain to allow it to form a “judgment” as to whether greenhouse gases endanger public welfare. Attached to this option (on what basis is unclear) is an essay requirement: “If,” the Court says, “the scientific uncertainty is so profound that it precludes EPA from making a reasoned judgment as to whether greenhouse gases contribute to global warming, EPA must say so.” Ante, at 31. But EPA has said precisely that—and at great length, based on information contained in a 2001 report by the National Research Council (NRC) entitled Climate Change Science:

“As the NRC noted in its report, concentrations of [greenhouse gases (GHGs)] are increasing in the atmosphere as a result of human activities (pp. 9–12). It also noted that ‘[a] diverse array of evidence points to a warming of global surface air temperatures’ (p. 16). The report goes on to state, however, that ‘[b]ecause of the large and still uncertain level of natural variability inherent in the climate record and the uncertainties in the time histories of the various forcing agents (and particularly aerosols), a [causal] linkage between the buildup of greenhouse gases in the atmosphere and the observed climate changes during the 20th century cannot be unequivocally established. The fact that the magnitude of the observed warming is large in comparison to natural variability as simulated in climate models is suggestive of such a linkage, but it does not constitute proof of one because the model simulations could be deficient in natural variability on the decadal to century time scale’ (p. 17).

“The NRC also observed that ‘there is considerable uncertainty in current understanding of how the climate system varies naturally and reacts to emissions of [GHGs] and aerosols’ (p. 1). As a result of that uncertainty, the NRC cautioned that ‘current estimate of the magnitude of future warming should be regarded as tentative and subject to future adjustments (either upward or downward).’ Id. It further advised that ‘[r]educing the wide range of uncertainty inherent in current model predictions of global climate change will require major advances in understanding and modeling of both (1) the factors that determine atmospheric concentrations of [GHGs] and aerosols and (2) the so-called “feedbacks” that determine the sensitivity of the climate system to a prescribed increase in [GHGs].’ Id.

“The science of climate change is extraordinarily complex and still evolving. Although there have been substantial advances in climate change science, there continue to be important uncertainties in our understanding of the factors that may affect future climate change and how it should be addressed. As the NRC explained, predicting future climate change necessarily involves a complex web of economic and physical factors including: Our ability to predict future global anthropogenic emissions of GHGs and aerosols; the fate of these emissions once they enter the atmosphere (e.g., what percentage are absorbed by vegetation or are taken up by the oceans); the impact of those emissions that remain in the atmosphere on the radiative properties of the atmosphere; changes in critically important climate feedbacks (e.g., changes in cloud cover and ocean circulation); changes in temperature characteristics (e.g., average temperatures, shifts in daytime and evening temperatures); changes in other climatic parameters (e.g., shifts in precipitation, storms); and ultimately the impact of such changes on human health and welfare (e.g., increases or decreases in agricultural productivity, human health impacts). The NRC noted, in particular, that ‘[t]he understanding of the relationships between weather/climate and human health is in its infancy and therefore the health consequences of climate change are poorly understood’ (p. 20). Substantial scientific uncertainties limit our ability to assess each of these factors and to separate out those changes resulting from natural variability from those that are directly the result of increases in anthropogenic GHGs.

“Reducing the wide range of uncertainty inherent in current model predictions will require major advances in understanding and modeling of the factors that determine atmospheric concentrations of greenhouse gases and aerosols, and the processes that determine the sensitivity of the climate system.” 68 Fed. Reg. 52930.

I simply cannot conceive of what else the Court would like EPA to say.

Conclusion

Justice Scalia lays the axe to the roots of this poisonous tree.  Even the scientific source document relied on by the majority admits that claims of man made warming are conjecture without certain evidence.  This case does not prove CAGW despite it being repeatedly cited as though it did.

Pacific, Not Arctic Ice Melting April 30

The image above shows the disappearing ice in the two Pacific basins over the last 16 days of April.  Okhotsk on the left melted steadily, losing 400k km2 of ice during this period, with only 260k km2 or 20% of its March maximum remaining. Bering Sea on the right actually gained 150k km2 ice extent up to 315k km2, before losing 215k km2 in the last four days, with only 100k km2 of ice left.

Meanwhile the Arctic core, Russian ice shelves and Canadian Archipelago remain frozen  The image above shows ice extent waxing and waning at the margins, especially in Bafffin Bay left of Greenland, and in Greenland Sea in the center.  Barents Sea on the right ended up about the same as it started this period.

The graph below shows how the April Arctic extents compared to the 12 year average and to some years of interest.
MASIE shows NH ice extents 800k km2 below the 12 year average at both the beginning and end of April.  SII ended the month slightly higher.  At this point 2019 is also tracking below 2018 and 2007.  The deficit is mostly due to open water in the Pacific basins.
The green line shows the average NH extents excluding Bering and Okhotsk ice,  The purple line shows the same for 2019, excluding B&O ice.  On day 90, the 12 year average included 1.7M km2 of B&O ice, which dropped to 0.9M by day 120.  In contrast 2019 started the month with 1.3M km2 of B&O ice, with only 0.3M left at month end.  As the table below will show, the over all deficit to average is 800k km2, and 550k km2 is due to Bering and Okhotsk melting.

Other than B&O losing ice, the other sizeable deficits to average are coming from Baffin Bay and Greenland Sea.  Of course, all of these basins will be ice-free as usual before September.

2019 Springtime in America: No Collusion, No Warming

Brian C. Joondeph writes at American Thinker Global Warming Going the way of Russia Collusion Excerpts in italics with my bolds.

The last thing we expect mid-spring is snow. Yet that’s just what we have. As the Weather Channel reports, “It may be late April, but Winter Storm Xyler will make you forget that it is spring in the Midwest this weekend as it is expected to bring some unusually heavy late season snowfall.”

Snow is heading to New York as well, despite the state’s all-out effort to combat global warming by attempting to ban plastic straws and now hot dogs. From the New York Post, “Upstate NY may get up to 3 inches of snow this weekend.”

Across the country in Denver, the weather won’t be much different, as The Denver Channel reports, “Mild through the weekend, cold, rain and snow next week!” What’s going on? I thought the planet was heating up, with melting icecaps, rising sea levels, and less than 12 years before the earth burns to a crisp?

We have been hearing this song and dance for several decades now. The global warming chicken littles keep telling us that snow is a thing of the past and we had better get used to it, along with a warming planet.

In 2000, British newspaper The Independent ran this headline, “Snowfalls are just a thing of the past.” In 2014, The New York Times ran a sequel headline, “The end of snow?”

Yet here we are, at the end of April, planting our gardens and facing snow in much of the country. If this is evidence of global warming, then Bernie Sanders’s popularity is evidence that the Democrat Party has shifted to the right. Good luck selling that.

One important factor always neglected by the climate warriors is the Sun, a ball of fire a million times larger than the Earth, the source of life on Earth, as well as destruction if the fires ever were extinguished, or expanded. If we were a few million miles closer to or further from the Sun, life on Earth would cease to exist. Just look at Venus and Mars, neighboring planets either too hot or too cold, respectively, for life as we know it.

Even the Earth’s tilt toward or away from the Sun is enough to cause our seasons, with large temperature variations and the difference between food production or not. Yet climate warriors ignore the Sun, instead focusing on human activity, driving SUV’s, flying in airplanes, and running our air conditioners.

Sunspots, according to the National Weather Service, “Are areas where the magnetic field is about 2,500 times stronger than Earth’s, much higher than anywhere else on the Sun.” Sunspots are quite large, about the size of the Earth, and are several thousand degrees cooler than the surrounding Sun surface.

Sunspots lead to solar flares, surface explosions which “release as much energy as a billion megatons of TNT.” These flares emit x-rays and magnetic fields which blast the Earth as geomagnetic storms, disrupting power grids and satellites, and warming the Earth.

Sunspots are not random but instead follow an 11-year cycle, from a minimum to a maximum. Sometimes the cycles last longer, for unknown reasons, with a 70-year period of near zero sunspot activity from 1645 to 1715, called the Maunder Minimum, or Little Ice Age. Enough of science class, how is this relevant now?

As reported by the Express, we are now entering one of these 11 year cycles as the Sun enters a solar minimum. As they report,

During a solar maximum, the Sun gives off more heat and is littered with sunspots. Less heat in a solar minimum is due to a decrease in magnetic waves.

Fewer magnetic waves equates to the Sun being slightly cooler, and experts are expecting the solar minimum to deepen even further before it gets warmer.

With less magnetic waves coming from the Sun, cosmic rays find it easier to penetrate Earth’s atmosphere and are more noticeable to scientists.

While cosmic rays have little effect on our planet, one of the reasons scientists monitor them is to see when the Sun has entered a solar minimum.

Now, with cosmic rays at an all-time high, scientists know the Sun is about to enter a prolonged cooling period.

The bottom line is that decreasing sunspot activity translates to a cooling planet, contrary to the doomsday non-scientific pronouncements of Al Gore and Alexandria Occasional-Cortex. Sunspot activity typically follows an 11-year cycle, but as noted above, there may be other perhaps longer cycles as occurred in the 1600s leading to a 70-year mini ice age.

Then there are even longer climatic cycles, with real ice ages occurring every 100,000 years. These glaciations end with a 10,000 year inter-glacial warming period, the current such warming period soon ending, as distinguished scientist S. Fred Singer wrote in American Thinker.

Clearly there are factors at play in climate cycles that we barely understand and certainly cannot control. Some play out in shorter time spans, which we as humans can observe directly. Others are on a far longer and grander scale than human existence, much less our individual life spans, which are merely the blink of an eye by comparison.

Aside from solar activity and sunspots, there are volcanic eruptions emitting more greenhouse gas per eruption than years of worldwide human activity. What other forces are at play? That’s for scientists to discover. Our solar system is a mere speck in the Milky Way Galaxy, which is another speck in the vast universe.

It’s the ultimate in hubris to believe climate revolves solely around human activity. Yet politicians, rather admitting the obvious, that we don’t know far more than we do know, blame an ever-changing climate on everything from flatulent cows to processed meats.

Much like the Russian collusion hoax, the left creates a narrative to fit their agenda, putting conclusions before research and discovery. Instead they would be better served by applying the scientific method of observing, formulating a hypothesis, testing it against observations, modifying and refining the hypothesis, until after extensive testing it accurately predicts future events.

Otherwise it’s just more blather and fear mongering, just as we heard for over two years with Russian collusion fantasies that turned out to be nothing. Just as late April snow, in the eyes of the left, is further evidence of a warming planet.

How Mass Media Became One-Sided

 

Joel Kotkin writes at New Geography on the forces that morphed major news media outlets from objective reporting to ideological mouthpieces, mostly aligned with progressive, social justice bias. His article is The Twilight of America’s Mega-Media. Excerpts in italics with my bolds.

It’s far too early to predict which party will win next year’s election, but not too early to announce the national media as a clear loser in terms of national influence and prestige.

Pew reports that millennials have become as negative about major media as older generations, with their rate of approval dropping from 40% in 2010 to 27% today. Gallup tracks a similar pattern, finding 70% losing trust in the media, including nearly half of Democrats.

As Trump backers never cease to point out, the Mueller report undermined the supposedly rock solid case for “collusion.” Whatever the truth, a solid majority of Americans believe the Russiagate brouhaha was politically motivated. Some progressives, like Rolling Stone’s contributing editor Matt Taibbi, believe Mueller represents “a death-blow for the reputation of the American news media.”

Ironically, Trump, the man the media wanted to bring down, was largely their creation. At a party in 2016, my wife and I were regaled by a CNN account executive crowing about the company’s strategy of using Trump rallies, at the exclusion of others, to boost ratings. Once having created President Frankenstein, CNN then tried to keep up the ratings by chronicling his disposal — this worked for MSNBC which, unlike CNN, never much pretended to be an objective network. Today, CNN’s audience share has fallen below not only leader Fox, but MSNBC, Home and Garden, Discovery and Food networks.

Ideology over journalism

By some estimates some 92 percent of all major network coverage of Trump outside Fox has been negative. This reflects a decay in journalistic standards. When I was a cub reporter at the Washington Post, I once tried to inject my opinion into an article. My editor came back with a remark that “no one gives a [expletive] about what you think.” Today the notion that news reporters should first and foremost inform, letting readers come to their own conclusions, seems almost quaint.

Today, many reporters ride fact-free, neglecting alternative views on such key issues as climate change, where even mild skepticism is ignored, or even the Trump tax cuts. This increasingly ideological cast has been worsened by journalism schools’ shift toward social justice advocacy; even well-placed writers at The New York Times complain about the stridency of younger journalists shaping coverage to fit their accepted ideological narratives.

The impact of the internet

Once there were bold notions of the internet helping to create an ever-expanding realm of options in the arts and journalism. Instead, as a Harvard study has demonstrated, we have increased geographic concentration of media in deep blue New York, Washington and, to some extent, the Bay Area, while local independent media continues to shrink.

The media’s tendency toward concentration — and ideological uniformity — reflects the dynamics of the tech industry. Google, for example, now controls nearly 90% of search advertising, Facebook almost 80% of mobile social traffic and Amazon about 75% of US e-book sales.

The traditional media now see much of their online sales largely enriching the world’s richest companies, and potential competitors. Pew reports that newsroom employment has dropped by 23% over the past decade. This does not even include the purging of experienced journalists frequently replaced by younger, less expensive and often ideologically driven younger reporters.

How the oligarchs are further undermining the media

Nearly two-thirds of readers now get at least some of their news through Facebook and Google. This dominance is even greater in both the United States and the United Kingdom among millennials who, by some accounts, are almost three times as likely to get their information from these platforms than print, television or radio.

The shift of control to Silicon Valley, located in one of the country’s most left-leaning regions, accentuates the progressive stranglehold on the media. Facebook’s attempts to “curate” content often eliminates conservative views, according to former employees. Over 70% of Americans, notes another recent Pew study, believe social media platforms “censor political views.”

Increasingly, the remnants of the old publishing industry are being bought by the oligarchs — Jeff Bezos’ purchase of the Post in 2013, the 2017 buying of the Atlantic by Laurene Powell Jobs, and last year’s purchase of Time by Marc Benioff, founder of San Francisco-based Salesforce.com. With billions made elsewhere, these media outlets no longer must listen to their diverse readers; Bezos did not buy the Post to defend democracy, as his henchmen insist, but to shape the debate in the nation’s capital.

Conflicts to come

Progressives may savor the media’s leftward tilt, but ultimately oligarchic control poses a direct threat to the grassroots left as well. Bezos’ tool, the Post, widely ridiculed Bernie Sanders in 2016 and will likely do so again. After all, the well-financed and well-liked Sanders, and other similar populists, may, if elected, relieve them of a few billion to fund his proposed “revolution.”

Hopefully, this pervasive group think will spur new alternative media committed to the credo that journalism best serves the public interest by offering unbiased reporting and heterodox opinion, not an ideologically driven algorithm.

Ottawa Signals Emergency Climate Virtue

Mark Bonokoski writes at Canoe: Progressive plaudits abound as Ottawa declares climate emergency Excerpts in italics with my bolds.

Our nation’s capital, always in search of the latest in political progressivism, has now joined the sky-is-dying crowd by having its city council officially declare Ottawa to be in a climate emergency.

This is in the nick of time, of course, but not because of the serious flooding currently ravaging the region, but because our country’s climate conscience Environment Minister Catherine McKenna keeps telling us that the planet has only 12 years left to sustain life.

There is no doubt the outlying burbs of Ottawa are again fending off rising flood waters because of a very snowy winter followed by a very rainy spring, but that is not the big-picture stuff, although Prime Minister Justin Trudeau said last week while filling sandbags for a photo-op that the current crisis is a direct result of climate change.

So, this wasn’t just a freak year. This was the new norm.

No, the real big-picture stuff is McKenna’s doomsday scenario that has her believing and preaching we’ll all be snuffed out by 2029 unless critical changes are made to ensure our planet’s orbit continues with us still aboard.

In Ontario, the successive Liberal governments of McGuinty and Wynne bragged about how they had at least saved their own province by shutting down all coal-fired power generation, tossing $2 billion down the toilet to cancel two gas-fired power plants, and spending multi-billions more on green-energy projects backed by influential friends who saw renewable energy as their licence to print money.

And they weren’t far wrong. Lots of former backroom types got rich, but it wasn’t the beleaguered taxpayer, because it was he who found himself having to choose between feeding his family or heating his home, and not how he was going to count all the money rolling in.

Or has everyone forgotten those stories? A lot of ink was spilled to report them, and a lot of fossil-fuel petrol was burned by television outlets dashing off to Smalltown, Ont., for first-hand coverage of outraged citizens living through trying times in homes without heat or light.

So, what good has green energy done for Ontario if cities like Ottawa, Kingston and Hamilton find it necessary to declare a climate emergency?

Renewable energy, despite costing billions of taxpayer dollars, is the source of less than 10% of Ontario’s electricity. Those vast fields of solar panels tilted towards the sun? Less than 2%.
Wind power, towering winged turbines that also drive countless nearby residents crazy with mysterious brain worms? Less than 8%.

A little over 90% of Ontario’s power sources — from nuclear plants to hydro dams — are environmentally friendly and without emissions.

Yet our nation’s capital has declared itself to be in the midst of a climate emergency, and spare us all if we sit idly by.

Ottawa Mayor Jim Watson was quick to point out that council’s climate emergency declaration is “no empty gesture,” although it came days prior to calling a real state of emergency over extreme flooding and getting assistance from 400 members of the armed forces to help cope with the crisis.

No, along with its specific climate emergency declaration, the city will prove it is “no empty gesture” by ponying up $250,000 out of its annual Hydro One dividend to do … what?

Why, to study the city moving to renewable energy, of course.

As if it had suddenly become a smart idea.

Background on Ottawa Resolution

Denis Rancourt writes at his blog change.org There is no evidence for a “climate emergency”. Stop the nonsense. Excerpt in italics with my bolds

There is an epidemic of cities in North America declaring that the city is in a “climate emergency”. This, below, is my recent submission to Committee opposing such a motion for Canada’s capital, Ottawa. There is no evidence that supports such a declaration. We should discourage our politicians from engaging in nonsense.

My signed submission document is also at: https://www.scribd.com/document/406277896/Dr-Denis-Rancourt-to-Committee-Enviro-Protection-City-of-Ottawa-2019-04-14

[The motion in Ottawa passed: 6 (for), 2 (against). Ottawa is therefore now in the throes of a “climate emergency”? The media refused to cover my scientific arguments and did not seek the views of the other side, whatsoever, despite several neighbours and Ottawa residents who agree with me.]

Summation

In conclusion, the Committee should take notice of the following facts when it considers this Motion:

(1) There is no conclusive scientific evidence that climate change (unnatural increased extreme-weather incidence) has occurred since the surge in use of fossil fuel that started in the 1950s. There is only tenuous theoretical conjecture that such might occur.

(2) Not a single death on Earth has been scientifically attributed to “climate change”, which includes Ottawa.

(3) Not a single animal or plant species has been scientifically established to have become extinct from climate change. There is no scientific demonstration of such a thing.

(4) Weather data for Ottawa does not show increased incidence of weather extremes, or any statistically meaningful deviations from the known natural variability (ENSO).

(5) Changes in Ottawa canal skating-season schedules result from ice-management and safety protocol changes, not from (empirically known) weather data.

(6) There is no rational reason, based on empirical data, to believe that Ottawa is at risk of climate change or is susceptible to anomalous future extreme weather events.

The Motion, in my opinion, is what can be termed “goodness propaganda”, which appears intended to convince citizens of being looked after. In fact, this Motion is a waste of resources and political attention.

It is verging on the ridiculous to think that the reality that 87% of world energy from fossil fuels (oil, gas, coal) can be changed by policy statements or taxation.[4] The only significant alternative contributors, as now demonstrated by decades of publicly funded adventures, are nuclear and hydro, both requiring massive structural investments, and both having large environmental consequences.

Climate Lemmings

Footnote

The Canoe article talks about the renewables small contribution to electrical supply in Canada.  The proportion of Canadian total primary energy shows wind and solar are far from being the solution.

In the Canadian Energy Fact Book, energy supply is equivalent to energy consumed, since it is calculated after adjusting for energy imports and exports. Note that 17.7% is the amount of energy from renewables, and hydro is 11.6%. Let’s see how much of renewable energy comes from wind and solar:

So Canadians actually consume 4.35% of their renewable energy from wind and solar. 92% of Canadian renewable energy comes from the traditional sources: Hydro dams and burning wood.

Combining the two tables, we see that 80% of the Other Renewables is solid biomass (wood), which leaves at most 1% of Canadian total energy supply coming from wind and solar.

Background:

The measles outbreak raises the issue of parents irrational fears of having their children vaccinated. SF Chronicle reports: All 10 kindergartens with the highest rates of vaccine exemptions are in N. California. Excerpts in italics with my bolds.

Ninety-five percent of the population needs to be vaccinated to stave off an outbreak of a very contagious disease, such as one that broke out at Disneyland in 2014.

Doctors say just 3 percent of children at most should be exempt, due to serious health complications, such as a child undergoing chemotherapy.

There is currently no authority in the state that decides on the validity of issued medical exemptions for vaccines.

California kindergartens with the highest medical exemption rates include:

58 percent: Sebastopol Independent Charter – Sonoma County
52 percent: Yuba River Charter – Nevada County
51 percent: Sunridge Charter – Sonoma County
43 percent: Live Oak Charter – Sonoma County
38 percent: Berkeley Rose School – Alameda County
38 percent: The New Village School – Marin County
37 percent: Coastal Grove Charter – Humboldt County
37 percent: The Waldorf School of Mendocino County – Mendocino County
35 percent: Summerfield Waldorf School & Farm – Sonoma County
33 percent: Santa Cruz Waldorf School – Santa Cruz County

Linking Fear of Vaccines with Fear of Fossil Fuels

Michael Lynch writes at Forbes Does The Measles Outbreak Have A Lesson For The Petroleum Industry? Excerpts in italics with my bolds.

Nearly everyone complains about the poor science literacy of the American public, but all too often they are referring to citizens’ refusal to believe what they want them to, whether its about climate change, vaccines, peak oil, or homeopathic medicine. The public has no problem accepting science (broadly defined) when it is to their benefit. Proposals to ban disposable diapers were popular briefly, before it was pointed out that the life-cycle effects of cotton diapers were not significantly better and possibly worse for the environment, after which the bans were quietly abandoned.

But the recent measles outbreak demonstrates a very important element of science literacy, namely the cost-benefit equation. People are relatively inattentive and more likely to adopt populist ideas when the impact on their lives is minimal, but employ more skepticism when the impact on their lives is significant. Although there are numerous cases of irrational fears driving policy, there are others where the public thinks more carefully.

Which is where the anti-vaccination movement can be a teachable moment. Until recently, criticism was primarily from those in the medical community. If the occasional child wasn’t vaccinated, it had little impact on others. But with this winter’s outbreak of measles, it has become obvious that there is a significant cost to the loss of herd immunity, and scrutiny of the science behind the anti-vaccination movement made it clear to many more people that it is somewhere between flawed and non-existent. Governments have put aside the passionate objections and demanded that vaccination be more widespread with much less resistance than would have appeared a few years ago.

Could this lesson prove valuable to the petroleum industry? There are two strong advocacy groups that are primarily passionate, not rational, with lots of overlap. Some oppose pipelines, thinking that will mean oil and gas will stay in the ground and not be consume, and others oppose fracking, in the belief that it is, well, scary or something.

Notice that no one discarded their cell phones when it was suggested they might cause brain tumors. Two elements seem to have come into play. First, the widespread use of cellphones without obvious negative health consequences encouraged skepticism about the possibility that there was a clear and present danger, as the saying goes. But also, giving up cellphones seemed like an unacceptable cost to most of the public.

Which is problematic for the petroleum industry. Banning fracking or pipeline construction appears much less contentious, especially where it is perceived as only affecting oil companies, or as many call them, “Big Oil.” In other words, such opposition is seen as cost-free and therefore easier to support, or at least ignore.

But familiarity is another element leading to acceptance. A couple of decades ago, I heard Michael Golay of M.I.T.’s nuclear engineering department talk about how new technologies were often resisted, but gradually became accepted as more and more people were familiar with them. (Railroads, cars, etc.) This certainly appears to be the case where nuclear power is concerned, as the operation of hundreds of reactors for decades has seen a total of two serious accidents (I don’t consider Three Mile Island a serious accident), but with two generations who have lived through operations of nuclear power with problems only under the most unusual of circumstances (a 1000-year tsunami), the early warnings of heavy death counts from nuclear power appear foolish.

The industry has tried to emphasize the fact is that both involve pipelines and fracking, while not ubiquitous like cellphones, have a long-standing provenance. There are 2.4 million miles of oil and gas pipelines in the United States, and over 2 million oil and gas wells have been hydraulically fractured. The industry has regularly pointed out these facts and they appear to have gained some traction, where mainstream politicians sometimes argue for tighter regulation, but few have embraced opponents.

Neither activity is completely safe, because nothing is completely safe. Having heavy trucks on highways increases fatalities, but no one suggests banning them, merely regulating them to improve safety. Banning cellphones would reduce deaths from distracted driving, but governments (with public support) have chosen to regulate them instead. Banning pipelines or fracking is not too dissimilar from those cases, except that it would not appear to have costs for the average citizen.

Because relatively few people were affected by bans on either (land-owners in western New York the most obvious exception), but as some gas companies cease new hookups because of lack of pipeline capacity, that could change. Unfortunately, the number of people affected will be minimal compared to, say, the threat from measles due to the anti-vaccine movement, however some of those will be small businesses that have more clout than home-owners.

Similarly, while the impact of any given shale well on world oil and gas prices is minimal, a slowing of fracking for oil could mean higher prices for consumers generally, especially given the current geopolitical situation. Which is not to say that the public should throw caution to the wind and allow both pipeline construction and fracking to occur without oversight, but merely that a more rational estimate of the costs and benefits should be made. This may seem like a vain hope, but remember, you can still buy disposable diapers.

Footnote:

One of the arguments by those fearing fossil fuels is that their use must stop now since we will soon run out of them.  Lynch rebuts this notion (“peak oil”) in the video below.  He addresses why people are mistaken to believe the following points of conventional “wisdom”:

Oil is finite and must run out.

Pundits are optimists, either conucopians or industry shills.

Reserve numbers are not reliable.

Only one barrel is found for every four consumed.

Frackingphobia: Facts vs. Fears

Why People Rely on Pipelines

Climate Boogeyman

As You Sow, So Shall You Reap.

This proverb from the bible draws an analogy from farming: The seeds you choose to put in the soil lead to different crops. Humans are responsible for the effects of their actions. If the action is based on goodness, it will churn out only goodness in the long run. If the action has been evil, the outcome also tends to be evil. The Holy Gita and Koran also emphasize the same. Goodness is the child of good deeds and misfortune and calamities are the children of evil.

Bringing this into the present, we are seeing the effects of environmental evangelists sowing seeds of fear into generations of children. The climate change movement has morphed into a doomsday cult, with those who have been duped taking to the streets like so many zombies with minds totally captured by fear. Could it be that the alarmists are ramping up fears of the climate boogyman just now, when indications of a cooler future are gaining strength?

We Have Nothing to Fear But Fear Itself.

Parents know that small children at some point become afraid of the boogeyman under the bed. Each child must confront the fear in order to go beyond it. Hank Aaron, #2 all-time home run hitter, said he was cured after his father pulled Hank’s mattress off the bed, putting it directly on the floor. In some way, every child must come to recognize the difference between figments of a fearful imagination, and realities to be faced and overcome. Sometimes people are consumed with doubt and fear as were Americans following the Great Depression. In 1932 Franklin D Roosevelt famously said upon taking office, “We have nothing to fear but fear itself.” He went on to say: “Nameless, unreasoning, unjustified terror paralyzes needed efforts to convert retreat into advance.”  Where, oh where is there such leadership today?

Bjørn Lomborg wrote about the overheated discourse that has children taking to the streets on the advice of adults who should know better.  Overheating About Global Warming was published at Project Syndicate.  Excerpts in italics with my bolds and images.

Decades of climate-change exaggeration in the West have produced frightened children, febrile headlines, and unrealistic political promises. The world needs a cooler approach that addresses climate change smartly without scaring us needlessly and that pays heed to the many other challenges facing the planet.

Across the rich world, school students have walked out of classrooms and taken to the streets to call for action against climate change. They are inspired by 16-year-old Swedish activist Greta Thunberg, who blasts the media and political leaders for ignoring global warming and wants us to “panic.” A global day of action is planned for March 15.

Although the students’ passion is admirable, their focus is misguided. This is largely the fault of adults, who must take responsibility for frightening children unnecessarily about climate change. It is little wonder that kids are scared when grown-ups paint such a horrific picture of global warming.

For starters, leading politicians and much of the media have prioritized climate change over other issues facing the planet. Last September, United Nations Secretary-General António Guterres described climate change as a “direct existential threat” that may become a “runaway” problem. Just last month, The New York Times ran a front-page commentary on the issue with the headline “Time to Panic.” And some prominent politicians, as well as many activists, have taken the latest report from the United Nations Intergovernmental Panel on Climate Change (IPCC) to suggest the world will come to an end in just 12 years.

This normalization of extreme language reflects decades of climate-change alarmism. The most famous clip from Al Gore’s 2006 film An Inconvenient Truth showed how a 20-foot rise in sea level would flood Florida, New York, the Netherlands, Bangladesh, and Shanghai – omitting the fact that this was seven times worse than the worst-case scenario.

A separate report that year described how such alarmism “might even become secretly thrilling – effectively a form of ‘climate porn.’” And in 2007, The Washington Post reported that “for many children and young adults, global warming is the atomic bomb of today.”

When the language stops being scary, it gets ramped up again. British environmental campaigner George Monbiot, for example, has suggested that the term “climate change” is no longer adequate and should be replaced by “catastrophic climate breakdown.”

Educational materials often don’t help, either. One officially endorsed geography textbook in the United Kingdom suggests that global warming will be worse than famine, plague, or nuclear war, while Education Scotland has recommended The Day After Tomorrow as suitable for climate-change education. This is the film, remember, in which climate change leads to a global freeze and a 50-foot wall of water flooding New York, man-eating wolves escape from the zoo, and – spoiler alert – Queen Elizabeth II’s frozen helicopter falls from the sky.

Reality would sell far fewer newspapers. Yes, global warming is a problem, but it is nowhere near a catastrophe. The IPCC estimates that the total impact of global warming by the 2070s will be equivalent to an average loss of income of 0.2-2% – similar to one recession over the next half-century. The panel also says that climate change will have a “small” economic impact compared to changes in population, age, income, technology, relative prices, lifestyle, regulation, and governance.

And while media showcase the terrifying impacts of every hurricane, the IPCC finds that “globally, there is low confidence in attribution of changes in [hurricanes] to human influence.” What’s more, the number of hurricanes that make landfall in the United States has decreased, as has the number of strong hurricanes. Adjusted for population and wealth, hurricane costs show “no trend,” according to a new study published in Nature.

Another Nature study shows that although climate change will increase hurricane damage, greater wealth will make us even more resilient. Today, hurricanes cost the world 0.04% of GDP, but in 2100, even with global warming, they will cost half as much, or 0.02% of GDP. And, contrary to breathless media reports, the relative global cost of all extreme weather since 1990 has been declining, not increasing.

Perhaps even more astoundingly, the number of people dying each year from weather-related catastrophes has plummeted 95% over the past century, from almost a half-million to under 20,000 today – while the world’s population has quadrupled.

Meanwhile, decades of fearmongering have gotten us almost nowhere. What they have done is prompt grand political gestures, such as the unrealistic cuts in carbon dioxide emissions that almost every country has promised under the 2015 Paris climate agreement. In total, these cuts will cost $1-2 trillion per year. But the sum total of all these promises is less than 1% of what is needed, and recent analysis shows that very few countries are actually meeting their commitments.

In this regard, the young protesters have a point: the world is failing to solve climate change. But the policy being pushed – even bigger promises of faster carbon cuts – will also fail, because green energy still isn’t ready. Solar and wind currently provide less than 1% of the world’s energy, and already require subsidies of $129 billion per year. The world must invest more in green-energy research and development eventually to bring the prices of renewables below those of fossil fuels, so that everyone will switch.

And although media reports describe the youth climate protests as “global,” they have taken place almost exclusively in wealthy countries that have overcome more pressing issues of survival. A truly global poll shows that climate change is people’s lowest priority, far behind health, education, and jobs.

In the Western world, decades of climate-change exaggeration have produced frightened children, febrile headlines, and grand political promises that aren’t being delivered. We need a calmer approach that addresses climate change without scaring us needlessly and that pays heed to the many other challenges facing the planet.

Call Me a Carbon Polluter? See You in Court.

Program Statement October 23, 2018:Canada’s plan ensures that polluters pay for their carbon emissions in every province

Justin Trudeau justified the federal carbon tax this way:

“The core of putting a price on pollution is exactly that. Making sure that pollution is no longer free. You’re making something you don’t want more expensive. We don’t want pollution, so we’re putting a price on it.”

Brian Lilly writes at Canoe Carbon tax court battle, advantage Ontario. Excerpts in italics with my bolds.

Last week the Ontario and federal governments battled it out in court on the carbon tax and it was the tale of two very different stories.

The opening arguments laid out by lawyers representing the opposing sides showed where they wanted to put their emphasis.

The lawyer for the Government of Ontario argued that the law was unconstitutional while the lawyer for the Government of Canada argued climate change was real, urgent and needed action taken.

One was a legal argument, the other emotional.

Given that judges are human, either could carry the day and anyone saying they know which side will win is fooling you.

Decades of following court cases have taught me that judges are unpredictable.

When he opened his arguments, Josh Hunter, deputy director for the constitutional law branch for Ontario, argued that the Greenhouse Gas Pollution Pricing Act violated federalism and the constitution.

Hunter was clear to say the Ontario government was not challenging whether climate change was real or action needed to be taken, they were challenging how the federal government was attempting to reach their goals.

“What this reference is about is whether Parliament can impose its solution to the problem on the provinces,” Hunter said. “Or whether in a federal country, the provinces have the flexibility under the constitution to choose what best meets their local circumstances as they work together to combat climate change.”

The argument from Ontario is pretty simple and rooted in legal concepts. Whether the judges buy those legal concepts remains to be seen, though I think they should.

The federal act imposing a carbon tax on some provinces and not others is a violation of our federal system, as well as an attempt by the federal government to encroach on provincial jurisdiction and, effectively, a violation of the “no taxation without representation” concept that has been part of our system dating back to Magna Carta.

Did you know the act setting up this system grants to cabinet and cabinet alone the ability to set the rate of the carbon tax and to adjust it as they see fit without passing another vote in Parliament?

Whatever you think of the carbon tax or climate change, that should be enough to have this act and the tax that goes with it declared unconstitutional.

For their part the feds admitted this act does infringe on provincial jurisdiction but then said that it does so minimally and therefore should be allowed.

Besides, they argued, against no one in the room, climate change is real!

“We know that climate change is an urgent threat to humanity,” said federal lawyer Sharlene Telles-Langdon.

“The accumulation of greenhouse gases in the atmosphere causes global warming which is causing climate change and the associated national and international risks to human health and well-being.”

I’m not saying that Telles-Langdon, the general counsel for Justice Canada, didn’t argue constitutional reasons for upholding the law, but she put the urgency of climate change front and centre at every turn.

That is a policy discussion and not a constitutional one, which tells me that even the feds think they have a weak argument on the constitution and want to win on emotion.

What didn’t help the federal argument was the release of the annual report from the federal government on greenhouse gas emissions by the province.

It showed Ontario had reduced GHG emissions by 22% since 2005. Without a carbon tax Ontario is most of the way to meeting its part of Canada’s target of 30% below 2005 levels by 2030.

British Columbia, the province that has had a carbon tax since 2008 and we are told is the model all should follow, is only down 1.5% since 2005.

As a whole Canada is up by 2%.

The question before the court is not one of the impact of climate change or the best way for governments to combat it — those are policy discussions.

The question before the court is one of constitutionality and on that front Justin Trudeau and his Liberals have failed.

Let’s hope the courts are guided by law and the constitution and not emotion or political inclination.

Footnote:

Ross McKitrick explains that economists do favor carbon taxes over cap-and-trade schemes, but on the condition that the tax replaces other fees, taxes and regulations intended to reduce emissions. That condition is never respected by Canada and other nations enacting such. McKitrick writes at Fraser Institute: Trudeau government carbon-pricing plan not in line with Nobel Prize-winning analysis

Canada has a patchwork of highly inefficient regulations with marginal compliance costs, in many cases well in excess of the conventional estimates of the benefits of greenhouse gas emission reductions. But rather than repealing the inefficient regulations and replacing them with a carbon tax, the federal plan involves adding even more regulations to the mix—then sticking a carbon tax on top. This looks nothing like what economists have recommended.

In fact the economics literature provides no evidence this would be an efficient approach, and some evidence it would be worse than regulations alone.
