Climate Change NOT as Advertised

Just before the Trudeau government imposed its Carbon Tax, it did a PR release advertising all the bad things we are doing to the planet, changing the temperature and weather by burning fossil fuels. Several skeptics pushed back (see links at end). This post is a synopsis of a complete rebuttal from Friends of Science. The whole document is interestingly written and presented, with only a few of many telling points highlighted here.

Climate Change Your Mind. Responding to the Canadian government’s “Canada’s Changing Climate Report” CCCR2019  Excerpts in italics with my bolds and headers

Federal Government says: Both past and future warming in Canada is, on average, about double the magnitude of global warming.

Friends of Science say: CCCR2019 used a reference frame that began in a cooler solar minimum and ended in a higher temperature El Nino period.

The CCCR2019 report uses 1948 as a reference point, a time when temperatures dropped significantly. Referring to this low period as a starting point gives a skewed comparison. In addition the referenced period from 1986 to 2005 ends with an El Nino year, where naturally-caused high temperatures were recorded. This gives a false impression that Canada is ‘warming faster than the rest of the world.’

Moreover, in the above graph all five major datasets show that since 2002, temperatures have Flatlined. This is despite a significant rise in carbon dioxide (CO2), shown by the upper squiggly line in the graph. The squiggles represent the seasonal rise in carbon dioxide during winter, when the great plains and forests are covered by snow, and the uptake of carbon dioxide by plants through spring and summer.

Federal Government says: Canada’s climate has warmed and will warm further in the future, driven by human influence.

Friends of Science say: CO2 Influence is not Seen in Canadian Temperature Records.

Canada has a seasonal range from cold to warm temperatures of 50°Celsius in the near land surface air temperature record. Using the recorded daily temperature minimums (TMIN) and maximums (TMAX) from 1900 to 2013 results in the red and blue colored graph above. A black line in the middle range shows the global temperature anomaly, indicating a tiny rise. At the bottom of the scale in the blue, it is clear there is a reduction in minimum temperatures (meaning overall it is less cold during coldest periods) of about 5°Celsius, but this is at the coldest end of the scale. There is no corresponding rise in the temperature maximum (which would mean hotter during the hottest times), which one is led to believe from the CCCR2019 report.

If carbon dioxide (CO2) was causing warming, it should have been visible in an increasing daytime maximum high, but there is no evidence of it.

Federal Government says: The effects of widespread warming are evident in many parts of Canada and are projected to intensify in the future.

Friends of Science say: Climate Models do not Reflect Observations.

If we are to rely on climate models for setting policy, we should expect that the models closely match observations. As you can see above, based on 102 model runs for the IPCC, the models project significant warming; the reality is that both satellite data and thousands of weather balloon records show that global warming has flatlined despite a significant rise in carbon dioxide emissions from human industry. The models did not predict this ‘hiatus. The theory of Anthropogenic Global Warming says carbon dioxide from human emissions drives warming – that is the impetus for the efforts to implement carbon taxes or invent ways to restrict or mitigate carbon dioxide emissions. The theory is flawed, as you can see above.

Federal Government says: Because of climate change, Canadians must face a ‘new reality’ that events such as spring flooding will be happening more and more frequently.

Friends of Science say: No evidence supports claiming seasonal or urban flooding is unusual.

As Dr. Madhav Khandekar, former WMO regional expert, past Environment Canada research scientist of 40 years, past IPCC expert reviewer, peer-reviewer and author of more than 150 peer-reviewed papers says that seasonal flooding in Canada is typically a combination of early warm temperatures over heavy snowpack and ice jams on rivers. If there are warm temperatures while the snowpack is still firm, the water rapidly pools and there is no open land to absorb the run-off. The flood waters often back-up, exacerbated by ice jams on rivers. This is a common occurrence throughout history, and little seems to be done by residents or municipalities to prepare for this reality. Since so many homes are on potential flood plains in Canada, shouldn’t building standards reflect this fact and municipalities require that new homes be elevated to mitigate potential damage?

CCCR2019 highlights the catastrophic southern Alberta/City of Calgary flood of 2013 as ‘probably’ caused by Anthropogenic Global Warming. This claim ignores the evidence that Calgary had eight of its worst floods prior to 1933. Had the CCCR2019 panel looked at the Calgary Public Library website or visited the Glenbow Museum, they could have seen the evidence for themselves.

Federal Government says: Coastal flooding is expected to increase in many areas of Canada due to local sea level rise.

Friends of Science say: Canadian coastlines are challenged by subsidence or erosion, not related to human-caused global warming.

Natural Resources Canada map shows regional uplift or subsidence.

However much of Canada is quite stable. In fact, due to the melting of the ice age glaciers, much of Canada’s land is in the process of isostatic rebound – a subtle, slow rise as the earth rebounds from the tremendous pressure of the kilometers of ice that once overlay our country.

CCCR2019 presumes that sea level rise from melting Greenland or Antarctic ice sheets will cause sea level rise issues to certain coastal areas in Canada, but this is not a foregone conclusion. Even if large masses of Greenland were to melt, the interior of Greenland is shaped as a bowl that would retain much of the meltwater.

As CCCR2019 notes, many northern regions of Canada are facing challenges due to permafrost melt and some communities face eroding coastlines. This may be seen as sea level rise, but it is due to subsidence or erosion, neither of which are related to human-caused global warming. In previous generations, northern residents were nomads, their ancestors simply moved camp to the most advantageous place for fishing, hunting or seasonal camping. Rather than proposing greenhouse gas emission targets, perhaps a more practical thing would be to design housing for northern communities that can be relocated. As more and more permafrost melts, more carbon dioxide and more methane will be released, however, a carbon tax will not stop that from happening. These are natural cycles. We must adapt.

    I love the graph showing temperature ranges and the predicted anomalies. Even if you include the max and min predictions it would make the same point.

      Thanks roger. It seems Bob Tisdale conceived that graph (H/T Willie Soon).

    Not to be a wet blanket, but in the southern hemisphere where 1/9 of humanity calls home, the seasons are the opposite, the moon is upside down, and no global warming is apparent from thermometer readings before or after 2002.
