I just don’t see any easy way to mitigate the consequences of the collapse of the Greenland Ice Sheet. Move inland?
Oy, thats almost like saying “I just don’t see any easy way to mitigate the consequences of the impact of an asteroid. Move to another planet”? You are asking us to assume the worst and pay for its planning.
The collapse of the Greenland Ice Sheet is inevitable under BAU scenarios. Once it starts, it couldn't be stopped. Since we don't know what's going to happen with energy, emissions, and the climate response, the question is when it's going to start. Not if -- when.
The other simple fact is that no matter what nonsensical things Todd Stern commits us to doing, it will make zero difference in climate (compared to natural variations).
