From Dr. Koonin’s email:

Tuesday, June 11, at 1000 US East Coast time, I’ll be in a live online conversation with Andy Revkin and Roger Pielke Jr. The goal is to test some of the ideas in my book Unsettled, whose updated and expanded edition will be released that day. 

Here is a description of the event and links to listen in/participate. 

It’s rare to get a serious conversation between informed people who have significantly different points of view. So this session might be quite informative.
