Dear Phil,

Sorry to bother you with this, but maybe you know something I'm missing.
I'm looking for the largest answers going with respect to what to do about
climate change, namely targets or general strategies. I'm certainly not
asking for your opinion, just help with research.

So far as I can tell, there's not much in the way of answers concerning what
to do. Probably we don't know, beyond the fact that our emissions are
increasing, and that's not good. But at least there's:

UN Framework Convention on Climate Change: 'stabilize GHG concentrations in
the atmosphere at a level that would prevent dangerous anthropogenic
interference with the climate system'. Working out what that level is is
the Big Question. I'm starting to think that there's no such level.

European Union seem to be hoping to limit temp increases to 2 C. (Too late.)

Contraction and Convergence: everybody aims for 450 ppmv by 2100.

Lots of other proposals and promises, which smell ad hoc, aiming to reduce
emissions by x% by some date or other.

Um, is that it? A sentence or two pointing me in other directions, if they
exist, would be very welcome.

Many thanks,
