Normal Arctic Ice Mid July 2023

 

The previous June Arctic ice update showed that shallow basins on the Pacific side lost their ice rapidly.  The animation above shows in the last 15 days how Hudson Bay (bottom right) is nearly all open water. And Baffin Bay (center right) is down to 22% of its March max. The images also show CAA (Canadian Arctic Archipelago–center bottom) is still blocking the Northwest Passage, despite open water in Baffin Bay and in Beaufort Sea to the west.  Also the Russian shelf seas (left) are starting to open. This is all normal melting of Arctic drift ice, presently at 56% (8.4 M km2) of last March maximum, heading toward the September minimum.

The graph for the last 30 days shows the normal melt is ~2.5M km2 down to 8.3 M km2.  2023 was above average for 3 weeks, and matching average the last week.  SII tracked the MASIE average throughout, as did 2007 in June, but dropped lower toward the end.

The table for day 197 shows how the ice extent is distributed across the Arctic regions, incomparison to 17 year average and 2007.

The table shows that Hudson Bay is the anomaly, melting out early, but will soon be matched by the average there.  CAA is also in slight deficit to average, while surpluses appear in Chukchi, Laptev, Baffin Bay and Central Arctic.  2007 was nearly 400k km2 lower than yesterday.

Reality Check on Extreme Weather Claims

CBS News headline was:  ‘Pacific Northwest heat wave would have been “virtually impossible” without climate change, experts say.’

Eric Felton provides a useful reprise of the campaign to exploit a recent Washington State heat wave for climate hysteria mongering.  His article at Real Clear Investigations is Does Climate Change Cause Extreme Weather Now? Here’s a Scorcher of a Reality Check.  This discussion is timely since you can soon expect an inundation of hype saying our SUVs caused whatever damage is done by Hurricane (or Tropical Storm) Henri, shown below approaching Long Island and New England. Excerpts from Felton’s article are below in italics with my bolds.

Henri 20210822

The Pacific Northwest was hit with a record-shattering heat wave in June, with temperatures over 35 degrees higher than normal in some places. On June 28, Portland, Ore., reached 116 degrees. Late last week the region suffered another blast of hot weather, with a high in Portland of 103 degrees. The New York Times didn’t hesitate to pronounce the region’s bouts of extreme weather proof that the climate wasn’t just changing, but catastrophically so.

To make that claim, the Times relied on a “consortium of climate experts” that calls itself World Weather Attribution, a group organized not just to attribute extreme weather events to climate change, but to do so quickly. Within days of the June heat wave, the researchers released an analysis, declaring that the torrid spell “was virtually impossible without human-caused climate change.”

World Weather Attribution and its alarming report were trumpeted by Time magazine, touted by the NOAA website Climate.gov , and featured by CBS News, CNBC, Scientific American, CNN, the Washington Post, USAToday, and the New York Times, among others.

The group’s claim that global warming was to blame was perhaps less significant than the speed with which that conclusion was provided to the media. Previous efforts to tie extreme weather events to climate change hadn’t had the impact scientists had hoped for, according to Time, because it “wasn’t producing results fast enough to get attention from people outside the climate science world.”

“Being able to confidently say that a given weather disaster was caused by climate change while said event still has the world’s attention,” Time explained, approvingly, “can be an enormously useful tool to convince leaders, lawmakers and others that climate change is a threat that must be addressed.” In other words, the value of rapid attribution is primarily political, not scientific.

550856_5_

World Weather Attribution was organized to quickly attribute extreme weather events to climate change.  World Weather Attribution

Inconveniently for World Weather Attribution, an atmospheric scientist with extensive knowledge of the Pacific Northwest climate was actively running weather models that accurately predicted the heatwave. Cliff Mass rejected the notion that global warming was to blame for the scorching temperatures. He calculated that global warming might have been responsible for two degrees of the near 40-degree anomaly. With or without climate change, Mass wrote, the region “still would have experienced the most severe heat wave of the past century.”

Mass has no shortage of credentials relevant to the issue: A professor of atmospheric sciences at the University of Washington, he is author of the book “The Weather of the Pacific Northwest.”

Mass took on the World Weather Attribution group directly: “Unfortunately, there are serious flaws in their approach.” According to Mass, the heatwave was the result of “natural variability.” The models being used by the international group lacked the “resolution to correctly simulate critical intense, local precipitation features,” and “they generally use unrealistic greenhouse gas emissions.”

WWA issued a “rebuttal” calling Mass’ criticisms “misleading and incorrect.” But the gauntlet thrown down by Mass did seem to affect WWA’s confidence in its claims. The group, which had originally declared the heatwave would have been “virtually impossible without human-caused climate change,” altered its tone. In subsequent public statements, it emphasized that it had merely been making “best estimates” and had presented them “with the appropriate caveats and uncertainties.” Scientists with the attribution group did not respond to questions about Mass’s criticisms posed by RealClearInvestigations.

But what of the group’s basic mission, the attribution of individual weather events to climate change? Hasn’t it been a fundamental rule of discussing extreme temperatures in a given place not to conflate weather with climate? Weather, it is regularly pointed out, refers to conditions during a short time in a limited area; climate is said to describe longer-term atmospheric patterns over large areas.

Until recently, at least, climate scientists long warned against using individual weather events to ponder the existence or otherwise of global warming. Typically, that argument is used to respond to those who might argue a spate of extreme cold is reason to doubt the planet is warming. Using individual weather events to say anything about the climate is “dangerous nonsense,” the New Scientist warned a decade ago.

noaa-us-temp-2019-2021

Perhaps, but it happens all the time now that climate advocates have found it to be an effective tool. In 2019, The Associated Press-NORC Center for Public Affairs Research and the Energy Policy Institute at the University of Chicago found that three-fourths of those polled said their views about climate change had been shaped by extreme weather events. Leah Sprain, in the book “Ethics and Practice in Science Communication,” says that even though it may be legitimate to make the broad claim that climate change “may result in future extreme weather,” when one tries “arguing weather patterns were caused by climate change, things get dicey.” Which creates a tension: “For some communicators, the ultimate goal – mobilizing political action – warrants rhetorical use of extreme weather events.” But that makes scientists nervous, Sprain writes, because “misrepresenting science will undermine the credibility of arguments for climate change.”

Which is exactly what happened with the World Weather Attribution group, according to Mass: “Many of the climate attribution studies are resulting in headlines that are deceptive and result in people coming to incorrect conclusions about the relative roles of global warming and natural variability in current extreme weather,” he wrote at his blog. “Scary headlines and apocalyptic attribution studies needlessly provoke fear.”

The blogging professor laments that atmospheric sciences have been “poisoned” by politics. “It’s damaged climate science,” he told RCI.

payn_c18450120210819120100

And not just politics – Mass also says that the accepted tenets of global warming have become a sort of religion. Consider the language used, he says, such as the question of whether one “believes” in anthropogenic climate change. “You don’t believe in gravity,” he says. The religious metaphor also explains why colleagues get so bent out of shape with him, Mass says: “There’s nothing worse than an apostate priest.”

That goes even for those who are merely mild apostates. Mass doesn’t dispute warming, he merely questions how big a problem it is. “We need to worry about climate change,” he has said. “But hype and exaggeration of its impacts only undermine the potential for effective action.”

Hottest Year Misdirection June Report

Activists and their media allies are Hell-bent to spoil our summertime joy by stirring up climate fear to further their zero carbon agenda.

The calendar turning to June and the official start to summer triggers the usual alarms that this year will surely be the hottest ever.  Headlines recently:

♦  Is 2023 going to be the hottest year on record?  World Economic Forum

♦  Why 2023 is shaping up to be the hottest year on record New Scientist

♦  Global temperatures in 2023 set to be among hottest on record  The Guardian

♦  2023 will be ‘one of the hottest on record’ says Met Office BBC

And of course you can count on NYT to totally jump the shark:

♦  The Last 8 Years Were the Hottest on Record – The New York Times

In the past few years, the earth cooled after warming from the 2015-2016 El Nino, and with higher North Atlantic summer anomalies repeating in 2020.  The cooling was significant as shown in the chart below (from the UAH satellite temperature dataset.)

The Global anomaly dropped from +0.7C January 2016 to <0.0C January 2023.  And of course the media ignored that cooling since they are addicted to the global warming narrative: temperatures can only go up, since CO2 keeps rising.  On the contrary, the chart shows CO2 did rise steadily, while temps fluctuated up and down, ending this period of 27 years flat.

Curiously, a lot of us have so far seen unseasonably cool temperatures this year, and wonder where this hottest year could be?  I mean, 60 cm of snow one June day in Jasper Park Alberta?   Suspecting that we have again a weather/climate perception that exists everywhere elsewhere, I turned to NOAA’s Climate at a Glance website to see what their data shows.

Climate reporting is confusing because the scope of temperature averaging gives very different impressions, and at the mega scale rarely corresponds to anyone’s particular experience.  So generalizations are claimed extrapolating from statistics, contradicted by many persons’ direct experience.

NOAA State of the Climate is another site advocating for the IPCC agenda and illustrates how this works.  First the Global Climate Report:

So there is the #1 hottest month out of 174 years–warmest Land, Ocean and combined Global.  Now let’s look at the year to date (YTD):

Whoops, that’s not as scary; the first half of 2023 is not #1.   Rather, the ocean is #2, Land #5, and the Global start to the year is #3.  And the table shows that 2016 was the hottest, consistent with the UAH graph above.  We start to see how media reports are speculating and hoping for this to be the hottest year, despite the first half of the year.

And to understand why most people will be put off by hottest year claims, we go to the Regional Analysis in order to see what the year has been like in various continents (land by definition).

It becomes obvious that no matter where I live, don’t tell me this is the hottest year ever. OK some Africans and Europeans may agree, but those in Oceania (mostly Australians) will boo you out of the room.

Note:  NOAA climatology data

The Extended Reconstructed Sea Surface Temperature (ERSST) dataset is a global monthly analysis of SST data derived from the International Comprehensive Ocean–Atmosphere Dataset (ICOADS). The dataset can be used for long-term global and basin-wide studies and incorporates smoothed local and short-term variations.

The Global Historical Climatology Network monthly (GHCNm) dataset provides monthly climate summaries from thousands of weather stations around the world. The initial version was developed in the early 1990s, and subsequent iterations were released in 1997, 2011, and most recently in 2018. The period of record for each summary varies by station, with the earliest observations dating to the 18th century. Some station records are purely historical and are no longer updated, but many others are still operational and provide short time delay updates that are useful for climate monitoring. The current version (GHCNm v4) consists of mean monthly temperature data, as well as a beta release of monthly precipitation data. [Reported station data are subject to adjustments by way of a procedure, known as the Pairwise Homogenization Algorithm (PHA)]

In addition, a previous post gives directions and links for anyone to get the unbiased climate history where they live, including the example of my locale.  See June 2023 the Hottest Ever? Not So Fast!

Footnote: Everyone has an agenda and packages data in support of their POV.  Those who joined the anti-hydrocarbon crusade are bound to find and amplify any bit of global warming they can find.  My agenda is for people to consider the full amount of relevant data and facts, and to reason accordingly rather than go along with the crowd or their feelings.  My approach is best expressed in this essay:

I Want You Not to Panic

June 2023 the Hottest Ever? Not So Fast!

For sure you’ve seen the headlines declaring June 2023 the Hottest month ever.  If you’re like me, your response is: That’s not the way June went down where I live.  Fortunately there is a website that allows anyone to check their personal experience with the weather station data nearby.  weatherspark.com provides data summaries for you to judge what’s going on in weather history where you live.  In my case a modern weather station is a few miles away  June 2023 Weather History at Montréal–Mirabel International Airport.  The story about June 2023 is evident below in charts and graphs from this site.  There’s a map that allows you to find your locale.

First, consider above the norms for June from the period 1980 to 2016.

Then, there’s June 2023 compared to the normal observations.

The graph shows May was warm, but not so much during June, pretty normal in fact.  But since climate is more than temperature, consider cloudiness.

Woah!  Most of the month was cloudy, which in summer means blocking the hot sun from hitting the surface.   And with all those clouds, let’s look at precipitation:

So, 19 days when it rained, including heavy rain, and sometimes thunderstorms, especially toward month end.  Given what we know about the hydrology cycles, that means a lot of heat removed upward from the surface.

So the implications for June temperatures in my locale.

There you have it before your eyes.  One Hot day, then cold, cool, warm
and ending comfortable.  Hottest June Ever!
Maybe in some imaginary world,  but not in the real one.

Summary:

Claims of hottest this or that month or year are based on averages of averages of temperatures, which in principle is an intrinsic quality and distinctive to a locale.  The claim involves selecting some places and time periods where warming appears, while ignoring other places where it has been cooling.

Remember:  They want you to panic.  Before doing so, check out what the data says in your neck of the woods.

 

Ten Days Melt in Hudson & Baffin Bays

 

The previous June Arctic ice update suggested that shallow basins on the Atlantic side will now lose their ice rapidly.  The animation above shows in the last 10 days how much open water has appeared in Hudson Bay (bottom right) and Baffin Bay (center right).  Just those two regions combined lost ~500k km2 of ice in 1.5 weeks and are now holding ~30% of their maximums.  The images also show little change elsewhere.  This is all normal melting of Arctic drift ice, presently at 63% ( 9.5 M km2) of last March maximum, heading toward the September minimum.

Insurers Playing the Climate Card

You’re probably seeing headlines like this one from The Hill Insurers pull back as US climate catastrophes intensify.   H/T Mark Krebs.  As usual, the Climate Card is a coverup for others who really are to blame for losses.  The linked article starts to look under the carpet, and I will dig deeper in this post.

Firstly, they label weather events as climate castastrophes in order to blame them on everyone else.  

From The Hill:

This month Farmers Insurance announced that it will no longer write new property insurance policies in Florida, citing “catastrophe costs … at historically high levels.” AIG also recently stopped issuing policies along the Sunshine State’s hurricane-vulnerable coastline.

State Farm, meanwhile, said in May, that it would impose a moratorium on new policies in California due to “rapidly growing catastrophe exposure.”

Mark Friedlander, director of corporate communications at the Insurance Information Institute, said that dozens of firms have reduced their presence in Louisiana, including 50 that have stopped writing new policies in the state’s hurricane-prone parishes.

Then in the article details, there are other factors causing claims, including bad governance

He noted that while Farmers made headlines, it’s the 15th insurer to stop writing new policies in Florida in the last 18 months. Although most of those companies have not pulled out of the state outright, he added, three have.

“Insurers are in many ways the first movers” in response to trends like extreme weather and natural disasters, Keys said. “They have a significant amount of money at stake, so they’re very exposed to the downside.”

Florida is in a unique position, Friedlander said, because of a combination of high fraud rates and widespread litigation, which both compound the cost of insurance on top of the climate risks. A state law enacted this year creates a backstop for property insurance in hopes of alleviating some costs, but it’s not yet clear how effectively it will counteract those factors, which have been building for years.

“The difference is in California and Louisiana, [insurance costs are] primarily climate-driven,” he said. “They don’t have the manmade factors we have here in Florida.”

“There isn’t an equivalent for wildfires in California, so the risks in California are borne much more directly. [Note:  Refers to California wildfires, which are uniquely a problem in that woke state which refuses to apply forestry management best practices.]

Insurance Industry Intends to Leverage Climate Fear

“The industry’s taking the approach now of what’s called predict and prevent, meaning being proactive to address climate risk and make sure insurance coverage reflects that and make sure homes and business take preventative action,” Friedlander told The Hill.

Keys also noted that the decisions don’t mean the insurers will never write policies or operate in the state again. Rather, he said, they should be understood as a way for insurers to negotiate, both on what they can charge in premiums and what factors they can weigh.

“It’s not that [insurers] don’t want to do business in your state, it’s that [they]
don’t want to do business at the current premiums [they] can charge.” 

Soaring School Insurance Costs Show How This Works

From Education Week Schools’ Insurance Costs Are Soaring—And Climate Change Isn’t the Only Reason.  Excerpts in italics with my bolds.

School districts are just like homeowners, renters, drivers, and small businesses—they need insurance, even as it’s become prohibitively expensive.

The 900-student Davis district in southern Oklahoma spent $61,000, or roughly $68 per student, on liability insurance for the 2019-20 school year. Last school year, the cost for the same coverage was $150,000, or $167 per student.  Next school year, it’ll be $261,000, or $290 per student. That’s a 328 percent jump just in two years.

Why is the cost of insurance rising so precipitously? Several factors provide clues.

For one, climate change is causing more frequent natural disasters that affect school district operations and require insurance companies to pay out. And it’s not only districts in hard-hit areas that see higher premiums as a result.

Districts’ coverage costs are increasingly determined by what’s happening nationally, not just in their own communities, said Kelli Hanson, executive director of the Schools Insurance Group, which provides insurance to schools in California.

“The more hurricanes we have in Florida, we’re impacted. The more flooding in the Midwest, we’re impacted,” Hanson said.  [Cashing in on Climate?]

Meanwhile, new laws allowing more lawsuits over sexual abuse are putting school districts in an unflattering legal spotlight—while also contributing to higher insurance premiums because of the added legal liability. In California, for instance, a new law passed in 2019 dramatically extends the statute of limitations for plaintiffs to sue over child sexual abuse, including in schools.

The growing frequency of cybercrimes is another factor putting districts at risk. The Shanksville-Stonycreek district in southwestern Pennsylvania saw cybersecurity insurance costs triple after a hacker got access to some of the district’s files in 2019, said Sidney Clark, the district’s business manager and board secretary.

And some districts have adopted controversial policies that are alienating their providers altogether. In Iowa, at least two districts nearly lost insurance coverage recently after they announced that they would be allowing teachers to carry guns on campus. After consulting with other providers who also wouldn’t commit to coverage, both districts have since nixed the policy.

In Oklahoma, one of two main providers of school property and casualty insurance shut down during the pandemic. As a result, Moring said, he has no choice but to sign up with the Oklahoma School Insurance Group (OSIG), no matter what its coverage plan looks like.

In turn, OSIG has struggled to keep rates down for the hundreds of districts in its membership, said Rick Thomas, a retired superintendent who has served as OSIG’s executive director for the last school year.

Over the last three years, Thomas said, OSIG has raised from $14 million to $30 million the amount of money it pays out to districts directly before seeking reimbursement from re-insurers—external companies that charge higher premiums.

School districts aren’t entirely powerless to stop insurance costs from swelling. In many cases, providers want to see that districts are proactively preparing for the unlikeliest scenarios.

Schools with safety plans with details on how they’ll deal with wildfires—what they’re doing to keep shrubbery away from buildings, how they’ll evacuate if necessary, for instance—are more likely to receive favorable insurance coverage, Hanson said.

Background from Previous Post Banking on Climate Alarm

The media are again amping up claims of bad weather to be feared from “climate change.” It is Whack-A-Mole time again, so here is a complete debunking of such media reports, compiled to refute a particularly bad speech by Mark Carney Governor of the Bank of England. H/T Friends of Science

Fact Checking Mark Carney’s Climate Claims is a useful reference document written by Steven Kopits of Princeton Energy Advisors. A few examples below show his systematic dismantling of the alarmist narrative by referencing publically available sources, many of them on government or corporate sites.

Temperatures Rising


We do have long-time series data for Central England, extending back to 1772. To the extent this measurement is reliable and can be extrapolated to hemispheric averages, it shows a step-up of about 1 deg Celsius from 1980 to 2005, which supports Governor Carney’s assertions. On other hand, it also shows a drop of 0.5 deg Celsius from 2005 to the present—which does not.

Sea Levels

As with just about every other metric the Governor mentions, we have data. Sea level is measured by tide gauges, and also by satellites. Satellite measurements suggest that sea level has been rising steadily by roughly 3 mm / year, which equates to about 1 foot per century.

Weather-related Insurance Losses

SOURCE: MUNICH RE NATCAT SERVICE

Hurricanes account for 75% of catastrophic losses, with typhoons representing an additional 8%. Thus, hurricanes and typhoons represent $6 of every $7 paid out in ‘top ten’ catastrophic weather-related insurance claims.

And this in turn tells us a great deal about the nature of insurance. Where do insured hurricane losses occur? Principally in the United States. Where do insured typhoon losses occur? Principally in Japan and Taiwan. Why these places? Because all of these are wealthy countries. Hurricane and typhoon losses will be greater where there is, first, a concentration of physical assets, and second, where those assets are valuable. In other words, in the advanced countries exposed to hurricanes and typhoons.

In this, no country is more exposed than the United States. Of overall losses due to top ten catastrophic weather events, nearly 2/3 occurred in the United States alone.

Insured Weather-related Losses

SOURCE: MUNICH RE NATCAT SERVICE

Indeed, if we restrict this to insured losses (including floods and tornadoes), the US accounts for 84% by itself.  Thus, if we are speaking of insured weather-related losses, as a practical matter we are speaking of hurricane damage in the US.  The rest is largely incidental.  For example, Superstorm Sandy caused more insured losses in one event than the cumulative and collective top ten catastrophic, weather-related losses from Europe, China, and Japan since 1980.  And Sandy was only the second worst insurance event in recent times. 

Now, why are US losses so great? Is it due to the number or strength of storms making landfall in the United States?

GLOBAL HURRICANE FREQUENCY SOURCE: RYAN MAUE

In fact, there is no such pattern discernible in the data. Indeed, the last few years have seen fewer than average hurricanes globally, with a recovery to up-cycle numbers in the last year or so.

Rather, reinsurance data hints at the source of losses: higher payouts for assets in harm’s way. 

INSURED LOSSES AS A PERCENT OF OVERALL LOSSES, TOP TEN LISTS, 1980-2014 SOURCE: MUNICH RE NATCAT SERVICE

Further, more and more expensive assets are exposed to hurricanes in particular.  In the US, for example, ever more people are living on the coasts, and beach front property has become prized and expensive.  One need only look out the window on a flight approaching Miami International Airport to be appalled at the sheer concertation of high-end housing built just above sea level on islands dotting Florida’s Atlantic Coast.   How long until a hurricane wipes a good number of these off their foundations?  And what kind of insurance losses will that involve?

Indeed, an examination of catastrophic losses suggests a decisive role for government policy.  Hurricane Katrina, which destroyed New Orleans in 2005, represents alone more than one-quarter of all insured top ten losses globally since 1980.  In just one event. 

The article goes on to deal with other claims regarding Floods, Droughts, Tornadoes, and Wildfires before reaching this conclusion.

Summing Up

In his speech to London’s insurance community, Mark Carney, Governor of the Bank of England, asserted a series of claims about climate change. Some of these are widely accepted. The climate does change. The world has warmed. Atmospheric CO2 has increased, half of the increment due to human activities.

Beyond this, there is no consensus, and indeed, the available data in many cases directly refutes the Governor’s more extreme assertions. There is no consensus that humans are the primary drivers of climate change. As we can see, sea levels, for example, were rising well before the 1950s date Carney gives as the start of modern anthropogenic warming.

Importantly, the increase in losses since the 1980s is more likely to reflect expanded insurance coverage, increasing payouts as a percent of losses incurred, and an increased number of assets with higher values placed in harm’s way. Losses increases have not occurred due to increases in hurricane, tornado, flooding, drought or fire frequency or strength, at least not in the United States, which represents the lion’s share of insurance claims. In many cases, either frequency or intensity of weather-related events has actually declined. Sea level rise has not accelerated, not as measured by either satellites or tide gauges. Sea level has been rising for well over 100 years, and continues on that pace.

Like so many other economists, Governor Carney seems to operate under the assumption that current CO2 levels are just on the edge of some catastrophic acceleration. For some reason, 320 ppm of atmospheric CO2 is safe, but 540 ppm is not, because there is some precipice—an inflection point or boundary—between here and there. The limit is not 1,000 ppm, or 5,000 ppm, or 42,448 ppm, but right here, right now. A little more CO2, a trace more of a harmless trace gas, and we are doomed.

The climate is complex and the future uncertain. It is possible the worst fears may prove correct. Nevertheless, such an assertion is not supported by the historical data, not for US droughts, floods, tornados, hurricanes or fires. But it does show up. In politics. If sea levels were 20 cm higher in New York and this contributed to the damage from Superstorm Sandy, well, any middling analyst could have predicted the rise back in 1940, just as we can predict today that sea levels will be one foot higher a century hence. The failure was not of CO2 emissions, but squarely a failure of governance. And that goes doubly so for the fate of New Orleans. If Governor Carney wanted to make a constructive proposal, he should have called for Lloyds to create macro audits of risk zones and censure or refuse to insure jurisdictions where governance is not up to par. If insurers had refused to insure New Orleans unless the levees were sound, they could have saved themselves $30 bn in payouts and probably twice that in losses.

As an analyst, I find Mr. Carney’s speech is truly dismaying. For the Governor of the Bank to claim that climate change is leading to rapidly rising insurance claims is, at best, a critical failure of analysis. As discussed above, insurance claims are a function of a number of factors, including the type and country of the weather event, as well as the extent of insurance coverage and payout ratios. A hurricane in the US may see one hundred times the payouts of a major flood in India. Payouts will rise as a function of nominal GDP, as both inflation and the value and concentration of assets will play a crucial role in overall losses. The specific path of a storm can also be decisive for global averages. It goes without saying that a storm which strikes in Philadelphia, marches up the New Jersey coast, slams into the Manhattan and turns towards New Haven is going to cost a bundle. That same storm hitting, say, rural Mississippi would cause a fraction of the monetary damages. And this matters, because Superstorm Sandy caused more insured damages than all the leading weather events in Europe, Japan, and China combined. Single events can move long-term global averages.

If the Bank missed this, it is not because the necessary data is hard to find. Information on weather-related events is readily and publicly accessible on the internet. Almost every graph I use above relating to hurricanes, tornadoes, floods and droughts comes from the US government itself. Apparently, the Bank of England could not be bothered to consult the underlying climate data before making hyperbolic claims. Thus, at best, the Bank was careless with data analysis.

A worse interpretation of events suggests that Mr. Carney was willing to blindly accept the conventional wisdom, the ‘consensus of scientists’ regarding global warming, without any will or curiosity to dig deeper and form a personal view. One can only hope that monetary policy in the UK is not informed by such superficiality or passivity.

The very worst interpretation is that Mr. Carney is in fact aware of the source data, but chose to make hysterical claims to promote a personal political agenda. I cannot imagine a more ill-considered idea. For those of us who consider central bank independence sacred, the appearance of a national bank taking sides in a highly charged political debate—and doing so with scant regard for the underlying data—will establish the Bank of England as partisan and the political opponent of conservative politicians. Given that Janet Yellen, the Chairman of the US Federal Reserve Bank, hails from Berkeley, a hot bed of climate activism, should the Republican Party consider the Fed also its opponent? If so, I can assure you, the Republicans will find some support to ‘audit’ the institution.

At the end of the day, political neutrality is a pre-condition for central bank independence. If a political party deems the central bank to be an opponent, then it will take measures to gain political control over the bank, with the result that monetary policy itself may become politicized. If the Bank nevertheless feels compelled to champion a particular side in a political debate, its analysis must be water-tight and its communication, impartial. That Governor Carny violated both dictums is simply stunning and a huge blow to the prestige of the Bank of England. It was a very bad call indeed.

Yes, We Will Avoid a Climate Catastrophe.

At Quora someone posed this  question:  Will we avoid a climate catastrophe just in time (please be positive I need some hope)?

Paul Noel ,Former Research Scientist 6 Level 2 UAH (2008–2014) wrote this response.  Excerpts in italics with my bolds and added images.

I have researched this issue in depth. As a good scientist I have gone deeply and gotten the facts. I have gotten:

  • the Satellite data on the global profiles,
  • the weather data.
  • the storm data and disaster data
  • the polar ice data.
  • the historical data.

I have looked in deeply on this issue. I have studied the physics too! I have studied the history too! I have studied the archeology and even the paleo geology and even the ice core data.

This isn’t easy to get because lots of people are producing lies on the topic. So I have worked very hard to get down to the facts. Then the job becomes one which is very hard. If I just tell you the answers I got , it is a case of if you believe me or not. If I tell you the science data it is likely to get way in over your understanding and that is back to if you believe me or not. This is a job of explaining to you very carefully what the data is using things you can see and understand.

So taking this from the top there are 2 ways I can go.
One way is to go into the advocates of the topic that are so scaring you deeply
and the other is to go into the science.

The explanation of the science is pretty easy and such but explaining to you the motives of people and their actions and methods is much harder. But I am going to start with the people.

Why are they scaring you about the climate?

Climate policy has almost nothing to do anymore with environmental protection, says the German economist and IPCC official Ottmar Edenhofer.

This is what this is all about. There is no other motive. You may dispense with your worries here if you are worried for the world environment. But I will now switch to the facts and reality on the ground. Remember this alone should pretty much put an end to your worries. You are facing a very large deliberate well funded and most professionally constructed set of lies and propaganda designed to get you scared like you are. This is 5th generational warfare. It is not anything you are used to thinking about. That is why it is effective.

What are the climate facts on the ground?

The fact on the ground are that if the changes you are supposing to see are real they should be obvious. They should be something you can see, feel, hear and touch. That is where we are going right now!

If the world is warming up the paleo-climate data says that the polar regions warm first. That is what you are being told about arctic ice melting and sea level raise. If you go to the Denmark Polar Portal on the web you can get the data.

Greenland Ice Sheet is not Melting Away

Because these people have to comply with the IPCC they put in all kinds of disclaimers trying to keep you scared of melt down etc.. The reality is we are solidly into the melt season and the ice is not melting down more than usual.

Arctic Sea Ice Is Not Going Away

The polar ice is at normal levels. I can go on and on here but the reality is that there is no emergency.

Global Warming is Not Accumulating

The data from UAH which is technical showed from January 1995 to January 2023 the global temperature did not increase at all.  And from 2016 actually went down (-0.7C) . That isn’t some melting or Global Warming or some Climate Catastrophe. It just is not.

CO2 Is Rising But Far Below Its Optimum

Is CO2 rising it sure is and it isn’t even to the maximum level that occurred in the last maximum in the last interglacial period of earth. CO2 is not 1% it is 0.042%. The earth has thrived with maximum life at 1% CO2 there are no melt down periods.

Is the climate variable, You bet it is. We have seen in the last 2000 years it go up and down in temperature and we are actually near the bottom of that period. The reality is that we have been up to 10C warmer and guess what that time mankind did his very best. We don’t thrive on cold.

Warming Has Been Beneficial and More Would be a Good Thing

Now let’s look at the trends and in a way you never imagined. I have looked into this matter because Alabama where I live has a cute lovely vacation town called Orange Beach. I highly recommend Orange Beach for a vacation it is beautiful. Orange Beach was named in 1898 when the US Post Office (Now the USPS) opened a new post office there. The unincorporated town’s principal business was raising oranges commercially. Alabama used to raise oranges up to about Evergreen Alabama or almost to Montgomery Alabama the state capitol.

 Production of Oranges Limited by Freezing Temperatures in SE US

No commercial orange production exists in Alabama at this time. The reason is simple. The growing season in Orange Beach Alabama went from 365 days a year to 268 days a year. The orange trees froze out. Now they have new varieties that can grow in the colder weather but even they are severely limited in Alabama. The orange trees have frozen out almost to Orlando Florida now.

Orange beach would be right next to North Florida along the Gulf of Mexico. Literally Florida is just across the Perdido River from Orange Beach.

The Gulf Stream Makes Climate Change in the North Atlantic

The reality is the climate from 1898 to the present has gotten colder in the USA. This is significant to the whole earth for a very important reason.

You see the heat from the whole earth gets aimed directly at Alabama! We cool down so is the rest of the world. The whole circulation for the whole earth focuses on the Gulf of Mexico and Alabama.

This by the way is why Greenland has so much ice. You see it is the warm water from the Gulf Stream that generates the steam that freezes and comes down as snow. You have to make the steam to make the ice.

Sea Level Depends on Land Buoyancy, not CO2

Now on to sea level rise. First of all if you believe that the sea level is rising and such it is only reported to be rising in the order of the thickness of 2 US 5 Cent coins per year. So if you believe it is happening it is no emergency and no real problem. It isn’t worthy of losing sleep over. The stories of melting sea ice are silly. First of all even if they melt they will have absolutely no effect on the sea level because they are floating. But there is another thing these people don’t tell you about.

The sea level is not the product of the amount of water in the ocean. It is in fact the product of a large sum of buoyancy issues and the gravity of the earth. The continents are where they are because they have less gravity than the other areas. The seafloor is a zone of higher gravity. Because the continents are floating that means that their level above the sea is determined by the laws of buoyancy. If Greenland were to melt off, the resulting reality would cause the area to buoy up because it would weigh less. At the same time the water added to the oceans would simply sink the sea floor deeper.

Continents Can Sink to Form New Seas

But to illustrate this you must learn about the Great Rift Valley of Africa. That valley is a place where the base continental rocks have spread apart. The land is sinking there and has already sunk to form the Red Sea! A new ocean is forming in Africa. This is what has sunk the continental shelves of the continents. The edge of the continents tinned out and lost the thick granite below that floats on the magma and they sunk. So sea level is not in any way related to ice melting. Sea level is related to this continental buoyancy issue. So nothing in their story not melting ice nor rising seas is happening. But I will show you this in pictures because we have these now.

Many Coastlines Show Water Receding Rather than Rising

Tell me if you see any sea level rise in the past 246 years now. (None!)

[Since we are looking in New England:]

This is just about due south of London–Pevensey Castle.

It was started construction in about 203 AD. It was built right on the sea on a coastal island. Such a fort only has value as far as an archer can shoot an arrow. It guarded the entrance to Pevensey Bay. The bay doesn’t exist it is nearly 30 meters above sea level now. Lots of people just refuse to see them. The fort itself is 110 feet above sea level and 5/8 mile from the sea.

If it isn’t clear yet that you have been hoaxed into a panic I don’t know what I can do. I have shown you that it got colder not warmer. That the ice is not melting. That the seas are not rising. Shall I go on?

CO2 Is Plant Food not a Pollutant

How about the real truth of CO2 and what it is doing on our earth. Look at these pictures carefully they tell the truth beyond any possible doubt.

C3 photosynthesis plants are growing 800% better than they were. Our C4 plants are doing 650% better.

The whole earth is growing better and the forests are growing because of CO2. Sorry this isn’t a “doom and gloom” story here.

Wild fires are down too!

The fact is that in 1960 the world was running out of food because our plants and farms were at their limits. Today we are run over with food and 45% of our crop land has been turned back to the forests. We are not at the limits. This has led to an explosion of wildlife too!

Life is Thriving Not Facing Extinction

There literally is no mass extinction going on. We are in the largest bloom of life on earth that has been seen in the past 10,000 years.

The human race is on the edge of unlimited energy, unlimited food, unlimited technology and we are sitting here in terror of some imaginary doom and gloom hating the very system that is feeding mankind and building him up.

Everything is quite literally the opposite of what you are told!

In Sum;

The only catastrophe would be ill-advised climate policies willfully destroying
our energy platform and economic supply processes out of irrational CO2 hysteria.

 

Hottest Year Coming Everywhere Elsewhere

In the past few years, the earth cooled after warming from the 2015-2016 El Nino, and with higher North Atlantic summer anomalies repeating in 2020.  The cooling was significant as shown in the chart below (from the UAH satellite temperature dataset.)

The Global anomaly dropped from +0.7C January 2016 to <0.0C January 2023.  And of course the media ignored that cooling since they are addicted to the global warming narrative: temperatures can only go up, since CO2 keeps rising.  On the contrary, the chart shows CO2 did rise steadily, while temps fluctuated up and down, ending this period of 27 years flat.

The calendar turning to June and the official start to summer triggers the usual alarms that this year will surely be the hottest ever.  Headlines recently:

♦  Is 2023 going to be the hottest year on record?  World Economic Forum

♦  Why 2023 is shaping up to be the hottest year on record New Scientist

♦  Global temperatures in 2023 set to be among hottest on record  The Guardian

♦  2023 will be ‘one of the hottest on record’ says Met Office BBC

And of course you can count on NYT to totally jump the shark:

♦  The Last 8 Years Were the Hottest on Record – The New York Times

Curiously, a lot of us have so far seen unseasonably cool temperatures this year, and wonder where this hottest year could be?  I mean, 60 cm of snow yesterday in Jasper Park Alberta?   Suspecting that we have again a weather/climate perception that exists everywhere elsewhere, I turned to NOAA’s Climate at a Glance website to see what their data shows.

Climate reporting is confusing because the scope of temperature averaging gives very different impressions, and at the mega scale rarely corresponds to anyone’s particular experience.  So generalizations are claimed extrapolating from statistics, contradicted by many persons’ direct experience.

NOAA State of the Climate is another site advocating for the IPCC agenda and illustrates how this works.  First the Global Climate Report:

So there is the #1 warmest Ocean, but we now can see the Land was 8th and combined Global is 3rd, not 1st.  Now let’s look at the year to date (YTD):

Oh oh, that’s not as scary; the first 5/12ths of 2023 are not #1, but the ocean is #3, Land #6, and the Global start to the year is #4.  And the table shows that 2016 was the hottest, consistent with the UAH graph above.

And to understand why most people will be put off by hottest year claims, we go to the Regional Analysis in order to see what the year has been like in various continents (land by definition).

It becomes obvious that no matter where I live, don’t tell me this is the hottest year ever. OK some Africans and Europeans may agree, but those in Oceania (mostly Australians) will boo you out of the room.

Footnote: Everyone has an agenda and packages data in support of their POV.  Those who joined the anti-hydrocarbon crusade are bound to find and amplify any bit of global warming they can find.  My agenda is for people to consider the full amount of relevant data and facts, and to reason accordingly rather than go along with the crowd or their feelings.  My approach is best expressed in this essay:

I Want You Not to Panic

Surplus Arctic Ice Mid June 2023

The graph for the last four weeks shows that 2023 Arctic ice continues to exceed the 17 year average from mid April to mid May. SII (Sea Ice Index) tracked MASIE with higher extents most of this period, while ending nearly the same.  Meanwhile, other years, especially 2010 and 2020 were losing ice much more rapidly than average.  

Why is this important?  All the claims of global climate emergency depend on dangerously higher temperatures, lower sea ice, and rising sea levels.  The lack of additional warming is documented in a post Satellite Temps Hit Bottom: February 2023.

The lack of acceleration in sea levels along coastlines has been discussed also.  See USCS Warnings of Coastal Floodings

Also, a longer term perspective is informative:

Overall, the extent is above average by 160k km2, or 1.5%.  The main deficits are in Barents, Kara, Hudson Bay and Okhotsk, more than offset by surpluses especially in Baffin Bay, Greenland and Chukchi seas. Note that Arctic extent will now go below 11 Wadhams heading toward its August minimum.  2010 was nearly 1/2 Wadham below average on day 166.

 

 

 

Climate Refugees Imagined Statistics

Any talk about climate (change, crisis, emergency, whatever) will include large numbers, scary enough to raise concern and support for the carbon crusade,  Of course, the implements of mass delusion are math models running on computers.  This is true of the ever-increasing range of climate sensitivity (how much warming from doubling atmospheric CO2), as well as the arbitrary choice of 1.5C warming as the tipping point into damnation.  And as this post explains, there are plenty of bogus numbers regarding climate “refugees.”

Disha Shetty challenges one common claim in her Undark article: Do Women Really Make Up 80 Percent of All Climate Migrants? Excerpts in italics with my bolds and added images.

The figure is frequently cited by activists, policymakers, and the media,
but it is a dubious statistic of murky origin.

Although climate change affects all people, women often bear the brunt in places where the impacts of climate change are already being felt. Christiana Figueres CNN

It is an alarming and evocative statistic: An estimated 80 percent of climate migrants are women. The figure has been used by the United Nations in its official communication. It has been repeated in the media and by human rights groups. But it stands on shaky scientific ground — and most likely is wildly off the mark. 

To begin with, the 80 percent figure fails the basic smell test. As someone who has reported on climate change and migration across India, it is clear to me that men are typically the first to move in the face of environmental pressures, often in search of seasonal income or jobs in cities. Women and children tend to be the last to go, if they leave at all.

Perhaps more importantly, there are currently no comprehensive datasets that can tell us how climate migrant populations break down along gender lines. In fact, experts say there isn’t even a consensus on the definition of who counts as a climate migrant.  When people migrate, it is often due to a combination of factors.  Environment, when it comes into play, is just one of them.

Where, then, does the 80 percent figure come from?

Lawrence Huang, an analyst at Washington, D.C.-based Migration Policy Institute, has fielded questions from the media on this number, and he says the earliest reference he can find to it is in a 2010 report by a nonprofit called Women’s Environmental Network. The report — which has been cited by the World Trade Organization, the Organization for Economic Co-operation and Development, and numerous other groups — states that “it has been estimated that women constitute up to 80% of global refugee and displaced populations.” It then infers, based in part on that figure, “that of the current 26 million climate refugees, up to 20 million are female.”

But the estimate seems to contain two big mistakes. First, it assumes that the gender breakdown of climate migrants mirrors that of populations displaced for other reasons, such as political unrest, economic collapse, and other disasters. In actuality, the demographics of a migrant group can depend on what’s driving their displacement. Studies suggest, for example, that refugees fleeing from armed conflict are especially likely to be women and children, with men often staying behind as combatants. By contrast, women made up the vast majority of people who remained in New Orleans in the wake of Hurricane Katrina, mainly because they didn’t have the means to flee.

That brings us to the report’s second big mistake. Its claim that women constitute up to 80 percent of refugee and displaced populations is attributed to a 2004 fact sheet on climate change and disaster mitigation, produced by the International Union for Conservation of Nature. That fact sheet doesn’t clearly specify a source, but its phrasing of the statistic bears resemblance to an often-repeated assertion, published in a 1999 report by the U.N.’s Inter-Agency Standing Committee, that “up to eighty percent of the internally displaced persons and refugees around the world are women and children.”

When people migrate, it is often due to a combination of factors.
Environment, when it comes into play, is just one of them.

Crucially, the 2004 fact sheet omitted “and children” from its phrasing of the statistic — as did the Women’s Environmental Network report that first applied the number in the context of climate change. It’s unclear whether the omission was intentional. (I was unable to reach the fact sheet’s author, Lorena Aguilar, despite multiple email attempts.) But what is clear, according to Huang, at least, is that the 80 percent figure “does not have a scientific basis” — especially not in the context of climate change.

“People just ran with the number,” Huang told me, noting that the statistic is used by some but not all U.N. organizations. On its website, UNHCR, the U.N. refugee agency, says that “[w]omen and girls make up around 50 per cent of any refugee, internally displaced or stateless population,” a classification that includes people migrating for reasons other than climate. Likewise, data from the U.S. Census Bureau indicate that women represent around 51 percent of people displaced by natural disasters. And yet the 80 percent figure has gained traction in the media and among policymakers and activists.

The potential consequences of this misinformation are many. First, by steering attention and resources toward women climate migrants, it could distract from the needs of women who haven’t been displaced but are impacted by climate change nonetheless. These women are affected in small and big ways. They often must take over agricultural and head-of-household duties from men who have moved in search of work, which places increased demand on their time and labor. Understanding the needs of these women is critical to crafting an effective response to climate change, but their narratives are often missing from media coverage.

Global warming could create 150 million ‘climate refugees’ by 2050. The Guardian (2009)

 Comment: 

The author is not skeptical enough to dig into the underlying claim that as of 2010 there are 26 million “cimate refugees.”

From NewScientist

When diplomats and military strategists gathered for a meeting of the council in July 2011 they asked a simple question: how many refugees can we expect as regions and countries become uninhabitable due to climate change? A clear-cut answer could spur politicians to do something about this problem. If only one could be found.

The first stab at an answer came in 1995 when British academic Norman Myers calculated there were 25 million environmental refugees, mostly in drought-hit parts of Africa. He predicted that numbers would swell to 50 million by 2010 and 200 million by mid-century. However, he did warn that his figures were “a first-cut assessment… to ‘get a handle’, however preliminary and exploratory, on an emergent problem of exceptional significance”. That was either foolhardy or heroic, according to your point of view.

The scandal is that those old figures still turn up in IPCC reports, the UK’s Stern review of the economics of climate change, and statements from the UN High Commissioner for Refugees (UNHCR). They do so because, as far as New Scientist can establish, nobody has attempted to improve on Myers’s “first cut” calculations. 

Important Finding, Nature Communications (2021) Climatic conditions are weak predictors of asylum migration

Recent research suggests that climate variability and change significantly affect forced migration, within and across borders. Yet, migration is also informed by a range of non-climatic factors, and current assessments are impeded by a poor understanding of the relative importance of these determinants.

Here, we evaluate the eligibility of climatic conditions relative to economic, political, and contextual factors for predicting bilateral asylum migration to the European Union—a form of forced migration that has been causally linked to climate variability.

Results from a machine-learning prediction framework reveal that drought and temperature anomalies are weak predictors of asylum migration, challenging simplistic notions of climate-driven refugee flows. Instead, core contextual characteristics shape latent migration potential whereas political violence and repression are the most powerful predictors of time-varying migration flows.

Future asylum migration flows are likely to respond much more
to political changes in vulnerable societies than to climate change.

Note: This is consistent with previous studies claiming climate causing displacement in Africa.  See
