The essential claim of the climate hysterics is that human use of fossil fuels is driving the CO2 content of the atmosphere higher which in turn is causing global warming which will have devastating consequences. Every part of which is essentially a fact-free lie. One underlying issue in assessing these hysterical pronouncements is the problematic nature of temperature measurement. Now we have satellites that do a commendable job, but that record only goes back a few decades at most. The land and sea-based use of thermometers of various types to measure temperatures also only extends for 100 to 200 years, and even then quite unevenly across the globe. The thermometers and measuring techniques have been shown to have multiple issues affecting accuracy and of course, we have “adjustment” efforts which tend to reflect the adjustors’ biases. Then there is urban warming impact, etc.
All of which makes a lot of the supposed temperature tracking less than trustworthy. But yeah, let’s go ahead and spend trillions of dollars to address a problem which has no solid factual or theoretical foundation. In any event, one adjacent claim by the hysterics is that we are seeing more extreme heat events, and at the same time and also caused by global warming, more extreme cold events. Turns out that just isn’t true. Researchers published a study in a Nature journal looking at the best temperature records they could find over the last 125 years and what they found was that both extreme heat and extreme cold had lessened. It is possible that human activities affect climate, particularly land use changes and extensive urbanization, but it would seem that if anything, those activities are ameliorating temperature extremes.
