Dr. Steven Koonin is the real deal. MIT PhD in physics. CalTech professor. Worked with Richard Feynman. Undersecretary for Science in the US Dept of Energy. In his new book, "Unsettled: What Climate Science Tells Us, What it Doesn't, and Why it Matters", Dr. Koonin explains in plain English why and how almost everything you're hearing about "climate change" is wrong and, from a public policy perspective, leads to regulations and laws that are more likely to be harmful than helpful." Really, this is a book that everyone should read and share.
