The Catastrophic Anthropogenic Global Warming (“CAGW”, aka “Global Warming”, “Climate Change”, “Climate Crisis”, “Climate Emergency”) scare is a failed hypothesis and the greatest scientific fraud in history. Global warming alarmism has been promoted by political extremists and believed in by their gullible acolytes for decades, even though there is no credible evidence that catastrophic global warming exists in reality, and ample evidence that the CAGW hypothesis has been falsified.
The failed CAGW hypothesis assumes that increasing atmospheric CO2 from fossil fuel combustion drives dangerous runaway global warming. The alleged evidence for this fraud is climate computer models that greatly over-predict current observed warming, typically by 300 to 500%. These climate models deliberately employ excessively high assumed values of climate sensitivity to CO2, and are designed to create false alarm.
Global warming has slowed since the mid-1990’s, so the climate alarmists alleged that increased atmospheric CO2 from combustion of fossil fuels will cause wilder, more chaotic weather. There is ample evidence that this allegation is also false. Weather has actually become less chaotic.
Atmospheric CO2 concentrations have been much higher in geologic time, and runaway global warming has never occurred in the billions of years of Earth history. Global temperatures have been much warmer and also much colder over geologic time. Earth is now in a glacial period, when mile-thick ice sheets cover much of the planet for about 100,000 years, interrupted by interglacials that last about 10,000 years. Earth is now in a warm interglacial, but the last glaciation ended only about 10,000 years ago, so Earth is due for another glaciation.
Temperatures were much higher during the Medieval Warm Period circa 900-1300 AD, and then humanity experienced the Little Ice Age circa 1300-1850 which caused enormous suffering and the deaths of millions.
The USA has some of the best surface temperature data in the world. The hottest USA surface temperature records occurred in the 1930’s, before fossil fuel combustion accelerated circa 1940.
It is highly probable, based on the evidence, that solar activity, not atmospheric CO2, is the primary driver of Earth’s temperature. In astrophysicist Willie Soon’s recent video, he shows the Sun-Climate relationship and provides his conclusions. There is strong correlation between the Daily High Temperatures and the Solar Total Irradiance (54:51 of the video):
