I'm in the middle here. If CO2 changes coincide with changes in world temperature, as implied above, then they must be linked. Our present increase in CO2 are man's doing, in having burned so much now.
I have always used the words "climate change", not "global warming".

I beleive in dealig with it, not griping about it.

I know the authors, especially the one with the most pragmatic experience, of a book called: Adapting buildings and cities for climate change, by S Roaf, D Crichton And F Nicol. Published by the Arcitectural Press
