Some times I think this guy's reading my mind - or maybe just my column. I'm talking about Donald Trump. Last week the president-elect had a talk on the issue of climate change with the Princeton physics professor who is my go-to guy on climate questions, William Happer. The Washington Post reported that the 77-year-old Happer didn't respond to reporters' questions after leaving the interview. But he did respond to me when I sent him an email.
