Re 9 wili — I know of a paper suggesting, as I recall, that enhanced «backradiation» (downward radiation reaching the surface emitted by the air / clouds) contributed more to Arctic amplification specifically in the cold part of the year (just to be clear, backradiation should generally increase with any warming (aside from greenhouse feedbacks) and more so with a warming due to an increase in the greenhouse effect (including feedbacks like water vapor and, if positive, clouds, though regional changes in water vapor and clouds can go against the global trend); otherwise it was always my understanding that the albedo feedback was key (while sea ice decreases so far have been more a summer phenomenon (when it would be warmer to begin with), the heat capacity of the sea prevents much temperature response, but there is a greater build up of heat from the albedo feedback, and this is released in the cold part of the year when ice forms later or would have formed or would have been thicker; the seasonal effect of reduced winter snow cover decreasing at those latitudes which still recieve sunlight in the winter would not be so delayed).

Overall, the panel's reports have never focused much on research examining how humans respond (or fail to respond) to certain kinds of risk, particularly «super wicked» problems such global warming, which is imbued with persistent uncertainty on key points (the pace of sea - level rise, the extent of warming from a certain buildup of greenhouse gases), dispersed and delayed risks, and a variegated menu of possible responses.

Like I say, you see a richness of behaviour in the models including in some occasions behaviour that at first sight looks not dissimilar to that highlighted in the observations by the Thompson paper and this on top of the «external control» as we called it in our 2000 paper in Science of the external forcings in a particular model which drives much of the multi-decadal hemispheric response in these models and which, in terms of the overall global warming response, is dominated by greenhouse gases.
