My take on James Hansen
I may have a different view of James Hansen than most. I have looked at a number of his statements / projections over time. Two things impress me.
While others call him an alarmist and worse, his projections have generally been about the most accurate description of what is happening and when they miss the mark, they are always too low. Climate Change is happening faster and with more effects than anyone anticipated. Obviously there are more positive feedback loops than known that are accelerating the process. So, when he says we need to get emissions back down to 350, I believe the number.
Secondly, I read Hansen as being very, very scared. His use of the term "Venus Syndrome" indicates the level of his apprehension and his view that we lack the political will to do what is necessary. Given that level of concern, I do not blame him for saying that we have to keep all options open, including CCS and nuclear. But, we had better do all of the other things to make sure that we don't really need those two.
