Co-Benefits for Air Quality and Climate: a little more to the story

Geoff over at China Green Buildings made an excellent point regarding CGS's recent "Air Quality in Beijing: Progress and Prospects" post. Geoff, in a great post on the Asian Brown Cloud, noted that according to the UN Environment Program, Asian Brown Cloud phenomena likely offset a rise in global temperatures as a result of greenhouse gas emissions by 20-80%. Working too hard to reduce air pollution might actually have substantial implications for the rate of global temperature increase. The message, I suppose, is that a co-benefits approach can't be pursued in isolation: the end goal still must be concrete, measurable, and verifiable reductions in the global GHG emissions budget.
