For a short, sharp take on the outcome of Paris, I think James at his Empty Blog is probably as good as any - as long as you read the comments too.
As I try to be a "glass half full" type of person, generally speaking, I find myself somewhat encouraged to read about the shocking pollution in China last week (and, perhaps, the incredible smoke problem stemming from Indonesia that blights neighbouring countries too) as giving reason for at least those countries to get serious about not burning carbon for reasons other than mere temperature rises and climate change. But then again, maybe I am being too optimistic (see The Economist's short take on the Chinese air pollution problem.)
I see that Lomborg has been The Australian's go-to boy for commentary on how the Paris meeting was all for nought. I see that Senator for Guns, Soccer Fans (but not Bicycle Helmets) Leyonhjelm tweet-cites him, which is a bit odd, given that Lomborg actually advocates a $100 billion to be spent on clean energy research. I thought small government types didn't trust governments to back winners.
By the way, Lomborg's website seems to contain even more selfies than Tim Wilson's twitter account, if that's possible. Wilson: "Oh look, here I am, in one of the crucial historical and cultural centres of the world, so let's take up half of this shot with my beaming face!":
And what the heck is he doing there at a meeting with the Palestinians and Bronwyn Bishop and Christopher Pyne?? See his twitter account, if his visage doesn't give you hives.
Update: John Quiggin's cautious optimism seems about right, too.
