A few things are unequivocal, perhaps (doubling
from the present concentration of CO2 will take 140 years [give or take]; the idea that the changes in climate since 1880 have been in the aggregate beneficial; it takes more energy to vaporize a kg of water than to raise its temperature by 1K; ignoring the energy cost of water and latent heat transport [in the
hydrologic cycle] leads to equilibrium calculations overestimating the climate sensitivity), but most are propositions that I think need more research, but can't be refuted on present evidence.
