Interesting full-length magazine article from der Spiegel that reviews where things now stand in the climate change movement. A set of reasons are given for why mankind has failed to effectively address a problem that is now so well-recognized. “Capitalism” gets a large share of the blame, but it is equally true that a new breed of capitalism has created and is deploying the technologies that could enable us to be rescued. The old breed still has plenty of money, and knows how to buy off politicians, so the fight goes on. The story includes some new information, and is very much worth reading for its deep perspective.

Why drill for oil off the East coast? I like this article from Yale environment 360 because it emphasizes the enormous damage inevitably caused by oil exploration and production, long before the stuff is ever burned. Wind and solar energy are not like that. Anyway, doesn’t the world already have tons of proven reserves that must remain forever in the ground? Obama needs to learn how to make these arguments.
