Cooling Trends in Climate Model Credibility

By Eric Dennis -- November 12, 2013

“Given the current state of climate science, I don’t see evidence that these and other complex interacting factors stand a reasonable chance of being predicted, beyond what is possible through a basic understanding of historical variability.”

The UN’s Intergovernmental Panel on Climate Change recently released its first major global warming manifesto since 2007. Once again, the IPCC makes dramatic predictions of future warming and catastrophic consequences due to manmade carbon dioxide emissions. Typically, these predictions are reported as proven “findings” that have the same status as the readings of a thermometer.

But predictions are fundamentally different from measurements, and the more complex the system, the more difficult the prediction. The climate is a complicated combination of atmospheric, land, and ocean systems whose dynamics must be pieced together on scales from the size of a single cloud to wind streams spanning continents.
