There appears to be a shift in the public mood about climate alarmism. The constant hyperbole has worn thin, particularly as the supposedly horrifying consequences of a warming world don’t appear. And of course, who really knows how much longer-term warming there is and why. There have always been climate shifts, over relatively short and longer periods. The default hypothesis is and should be that any warming is natural, just part of the intense variations that have always been experienced. If you think something done by humans contributes, you have to prove that to a high degree of certainty, particularly when you proposing that trillions of dollars be spent and everyone’s quality of life gets disrupted by your solutions to what likely is a non-problem.
Here is another study finding that the warming that has been experienced, and let’s be clear, there is a reasonable debate about how much warming there actually has been, is largely driven by natural variation and factors. The author notes the dissonance between the widely cited climate models and real-world measurements on the effect of rising CO2 concentrations. Using data on solar energy reaching and permeating our atmosphere and ocean heat data, he suggests that two-thirds of any warming is due to natural processes and variation, and perhaps a third to higher CO2 levels.
