Well, the thing with GHG-induced climate change (not counting wetbulb temperature that will be reached more than a hundred day a year in some highly populated areas) is that the troposphere become warmer while the stratosphere become colder.

I'd be interested if you can guess the fantasies i have knowing that.

Also, endogenic species are dieing faster than the forest replace them, forests are dryer, this summer we were 50km close to have the Russian weat fields burn more than they did in 2010 (with effects on the world hunger and politics in 2011 well know). This could be mitigated honestly, and i'm pretty sure that this, we can manage. Katrina every year, maybe not as much.
