Greenhouse gases increasing--but still no evidence of warming

One of the motivator for this blog was the battle over greenhouse gases. Well, it appears that the greenhouse worry warts finally have some convincing evidence on their side. ( slashdot on green house gases)

Still to be addressed are

• what the implications will be
• what the economics choices are
• is the benefit of doing something larger than the cost.

This last question is the line that I personally draw in the stand. If the benefit is 100 years away, we need almost a 100 times return before it is a positive value project. There are so many other things that sound more important, that I truly have trouble getting excited about this one.
