APS Workshop on Climate Change

     In January, 2014 the American Physical Society (APS) held a one day workshop on climate change and invited six climatologists to participate.  A full transcript of the workshop can be found here. The six speakers are all very eminent climate scientists.  The discussion was limited to the physical basis of climate change and atmospheric physics was the predominant topic.  Three of the speakers lean to the alarmist view. That is they think we are headed toward a climate catastrophe due to man-made Carbon Dioxide. These are Dr. Held, Dr. Collins, and Dr. Santer.  The other three lean to the skeptical view and do not think we are headed to a climate catastrophe caused by man-made carbon dioxide. These are Dr. Curry, Dr. Lindzen and Dr. Christy. (click here for a brief bio of each)
     Climate science and the debate about it are much more complex than the media, the politicians and public know. This workshop drilled down to the root of the disagreements and reading it reveals the considerable uncertainty in estimates of both climate sensitivity to CO2 and the effect of natural long term climate cycles.
      This transcript (click here) is as good at explaining the issues. Professor Judith Curry said, “ This is a remarkable document… it provides in my opinion what is the most accurate portrayal of the scientific debates surrounding climate change.”
