I confess that I just wanted to suppose that 3 K in 100 years is within the "normal" range for the sake of argument, and that I did not check numerical values of rate of past climate changes from reliable estimates. What I had in mind was the rate of increase of temperature at the end of stronger cold phases of Dansgaard-Oeschger oscillation. Some say that coherent variation is found in many parts of the world, and I tentatively followed that interpretation. If incoherent, global mean signal should be smaller. Ko-1 M.
