An excellent, excellent link provided by my Illustration professor via Facebook: Everything You Need to Know About Global Warming in 5 Minutes. His postscript:

[Jeremy] Grantham is an institutional investor who other institutional investors read. He invests based on data and is one of the few who does not politicize facts.

People who find themselves on the other side of the argument with Grantham reexamine their conclusions because it’s been a bad idea to bet against him in the past.
