You will not often catch me linking to the NY Times, but this Tierney article linked over at Instapundit has some interesting features. The writer believes that Global Warming is anthropogenic and that we should act on that, but he doesn't think catastrophic scenarios are at all likely. He also recommends we encourage private solutions.
I think that's about right. I would add in my long-term fondness for the low-environmental impact solutions of ANWR and offshore drilling, plus nuclear power. Oil shale/tar sands are excellent long-term solutions, but still need some development, both economically and environmentally.
