James Hansen on Climate Change

Dr. Hansen is well-qualified to speak on the subject of global warming and in this lecture describes the underlying principles and evidence for the changes we now observe. He also makes predictions for the future against the accuracy of prediction he has made over the past several decades, all of which are now fact or on the predicted track. Dr. Hansen is the target of attacks about his views of a proposed economic method to reduce carbon emissions and about his claim that NASA tried to muzzle his alarm about climate change.

Here is his talk March 10, 2012.
