While the science of how CO2 and other greenhouse gases causes warming is fairly well understood, this core process only results in limited, nuisance levels of global warming. Catastrophic warming forecasts depend on added elements, particularly the assumption that the climate is dominated by strong positive feedbacks, where the science is MUCH weaker. This video explores these issues and explains why most catastrophic warming forecasts are probably greatly exaggerated.
This is a companion video to the longer and more comprehensive climate skeptic video "What is Normal -- a Critique of Catastrophic Man-Made Global Warming Theory."
