Quick, somebody buy Michael Tobis a new set of worry beads:
The evidence is piling up that our circumstances are beyond our cognitive or managerial abilities. I'm more scared of that than of hundred degree oceans right now. I think at the present rate we will not manage to maintain what we are pleased to call civilization long enough to get to 5xCO2. I suppose you could say that may be more good news than bad news; at least a few vertebrates will straggle through.
At his "present rate" of doomsday/media kvetching, I have to wonder how long Tobis can tolerate hearing himself say the same things, ad nauseum.
