Climate Tutorial Submitted for Federal Judge William Alsup

March 19, 2018

Our understanding of climate and climate change is fraught with uncertainties but the best available evidence does not indicate catastrophe is in the offing.

William Happer, Ph.D., President of the CO2 Coalition, Richard Lindzen, Ph.D., a Coalition Director, and Steven Koonin, Ph.D. responded to a request from U.S. District Judge William Alsup to answer questions concerning climate change and climate science for the lawsuit he is hearing in which the cities of Oakland, San Francisco, et al. are sing various large large oil companies for emitting carbon dioxide and supposedly misleading about the dangers of climate change.

This brief is in response provides a tutorial on climate change and climate science and shows there are numerous uncertainties concerning the causes and consequences of present climate change, but the best evidence right now indicates a climate catastrophe is not in the offing.
