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. These are Dr. Curry, Dr. Lindzen and Dr. Christy. Short biographies of each of the speakers can be seen here. Someone new to the climate change debate would have a hard time telling the alarmists from the skeptics from this transcript. They were all very professional and they stuck to the science as their host, Dr. Koonin, requested. Climate science and the debate about it are much more complex than the media, the politicians and public know. This workshop drills 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.
