Introduction – Catastrophic Anthropogenic Global Warming – A Failed Hypothesis
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.
