I was doing a bit of research on ice cores when I tripped over a video 0f Ivar Giaever speaking before the 2012 Lindau Mediatheque, the 62nd meeting of Nobel Prize winning physicists. Dr. Giaever made news at a 2008 meeting of this society when he was on a panel discussing global warming.
Dr. Giaever gave a speech critical of global warming science. The lecture is both entertaining and informative. It’s worth a look.
