(For instance, do the models predict cooling after big volcanic eruptions?

I think there is an important context here that is easy to lose in all of the emphasis on the thing that the trees don't appear to be doing well w / (i.e. the response to the high - frequency cooling events associated primarily with explosive volcanic eruptions): that's, the thing that the trees appear to be doing remarkably well with, i.e. capturing the long - term trends and low - frequency variability that is predicted by the climate model simulations.
