If «a constraint is satisfied by one or more low sensitivity models and one or more high sensitivity models,» with model weighting, at least this would be reflected in the posterior ECS — in that it may not be much different from the prior. (climate-dynamics.org)
«the only valid argument against low sensitivity is that we have failed (thus far) to build low sensitivity models that can simulate some features of the 20th century climate.» (julesandjames.blogspot.ru)
A recent study used NASA satellite observations to test the skill of climate models in simulating this cloud - type transition, and found that high sensitivity models simulate it more accurately, while low sensitivity models tend to overemphasize its climate cooling effect. (giss.nasa.gov)
