Chamber of Commerce - leave it or fix it?

A major California utility, PG&E, has left the US Chamber of Commerce due to frustration with the Chamber's denialism. I've argued for "Greening the Chamber" by getting green businesses to change its policies, but there's something of a contradiction between quitting it and fixing it.

I'd still go for fixing it. The link describes a conversation with Microsoft about its continued role in the Chamber, despite Microsoft's opposition to the Chamber's policy. Corporations like Microsoft might be willing to work for change, but I don't think they'd be willing to quit. Also, green businesses could change local and state level Chambers even before they affect the national level, so it's not an all-or-nothing quest.

Other interesting news: Warming Law discusses the nuisance case against greenhouse gas polluters that has just passed an important hurdle of being accepted at the appellate level. It's possible that the Supreme Court will kill it, but I wouldn't count on it. Good news, and one more bargaining chip to help push the polluters in the right direction.
