Who knew? Well, I did, for one, a couple of years ago:
Am I really supposed to believe that financial instruments can actually counteract the combined power of the Sun, the oceans, and the 99.97% of our atmosphere that isn’t CO2? No thanks, but you go right ahead.
I’m glad that financial markets exist, and they are very useful for many things. However, changing the climate is not one of them, in large part because CO2 is only .035% of the freaking atmosphere.
