Is a Popular Carbon-Offset Method Just a Lot of Hot Air?-Scientific American

http://www.scientificamerican.com/article.cfm?id=a-mechanism-of-hot-air#comments

Although this article, which talks about the drawbacks and shortcomings of carbon trading, does make several good points, I'd like to point out the comment made by rwilliston. To summarize it briefly, it says that although carbon trading may not be the best possible solution for climate change, merely complaining about the inadequacies of the system is not productive. In addition, the poster points out that the system in place is necessary because only once there is such a system established can we try to improve on it.

Kudos to rwilliston.
