We welcomed Dr. Judith Curry to the show to discuss climate science as Dr. Curry is a noted climate scientist from Georgia Institute of Technology. Follow Dr. Curry on her exceptional blog, Climate Etc. @ http://judithcurry.com. Her faculty page website at Georgia Tech is http://curry.eas.gatech.edu .

In the first few minutes of our 55 minute discussion with Dr. Curry, I asked her for a brief history & time line of when the issue of climate science got the attention of the public and started to be highly politicized. Dr. Curry traced it back to the late 90s and then the 2001 UN Assessment. I asked her about the partisanship, the public being confused, and more and she said these were normal states to be in regarding climate science which she said several times during the show was a “wicked mess.” Dr. Curry then gave us a brief history of warming trends going back hundreds of years, their possible causes and then she talked about the complexity of climate data and how hard it was to correlate, make assumptions with, and to draw useful conclusions for sound policy making. We talked about multiple sources of data collection from space resources to climate models. Regarding climate models, she said they run hot, everyone knows it, but it is very hard to fix the problem and then she explained why. Listeners asked about bias in the data, news reports, even with other scientists. Bias and the use of proxies to spread this or that perspective on climate science was all too common and is a problem. Another of Dr. Curry’s points was that given the problems with climate data, there are “deep uncertainties” regarding the state of climate science but that does not mean the risks should be ignored. The balancing act is to understand the data as objectively as possible to manage the risks in the best way possible. When asked by listeners about regulations, she said that a better way to mitigate possible climate problems was through the use of technology and innovation. Don’t miss her comments about this, especially as she applied them to the energy business. She also brought up the risk of serious unintended consequences to whatever we do, whatever policies we put in place, again because there is so much uncertainty with the data and the subject is very complex and not lending itself to simple solutions. Dr. Doug called the show to ask about solar cycles. Doug kept asking the question though our guest did respond. Specifically, I believe Doug was asking her how solar cycle length correlates with global surface temperatures. Listen to the exchange and see what you think about this mini-discussion. Later Doug sent me a graphical image related to his series of questions but our discussion had moved on plus I had no way of getting the graph to Dr. Curry for discussion. Listeners asked Dr. Curry about emissions, CO2, regulatory mandates and policy. Another question for Dr. Curry focused on scientific consensus regarding climate change issues. Don’t miss this discussion. BJohn asked about planetary science & solar system climate studies. Later, she was asked about testifying before Congress. Dr. Curry said there was a difference between testifying in the House as compared to the Senate. I asked if she had ever given a presentation to the UN or elsewhere. In response, she talked about her recent experience speaking before Parliament in the UK to the House of Commons. Compare what she said about the UK experience to her congressional experience. Near the end of our discussion, Dr. Curry spoke about her climate change and science blog, Climate Etc. per the above URL. If you are interested in these subjects, following her blog would be highly beneficial. Before the program ended, I asked if her graduate students came to the classes with a bias or if they were open minded in their climate science studies. I then asked if climate science in the U.S. was dependent on who the president was and what party was in power. Dr. Curry had very interesting comments on this plus she gave us the recent history of what happened to the field over the past several administrations, both Democratic and Republican. Finally, I asked how important it might be for the general public to have a good, bias free understanding of climate issues. Her response might surprise you so make sure you hear what she had to say about this and science education in general. A last minute question was asked about the famous hockey stick graph, then our guest provided us with good, solid closing comments.
