"not possible" is hard to defend IMO.
I have a handful of model simulations which give a reasonable climate
under present day conditions but show runaway global warming under 2xCO2
and even 1.4xCO2 in one or two cases (about where we are now!). These
models are in the same class as the CPDN ensemble, ie a fully-fledged
atmospheric GCM coupled to a slab ocean, so designed for looking at
equilibrium climates, based on our detailed understanding of the myriad
interacting physical processes.
I suppose I should submit it to Nature :-) But when a Japanese model
gives a crazy result, everyone says "that's a crap model". When HadCM3
gives a crazy result, everyone say "ooh that's scary, we're all going to
die".
