Most past modeling experiments that investigated the atmospheric response to Arctic change only considered the loss of sea ice, which of course misses much of the effect of Arctic amplification.

Polar amplication is of global concern due to the potential effects of future warming on ice sheet stability and, therefore, global sea level (see Sections 5.6.1, 5.8.1 and Chapter 13) and carbon cycle feedbacks such as those linked with permafrost melting (see Chapter 6)... The magnitude of polar amplification depends on the relative strength and duration of different climate feedbacks, which determine the transient and equilibrium response to external forcings.

I was thinking instead perhaps more easily controlled polar - orbit satellites might be used, which would rotate with some fixed ratio to their orbital period, casting greater shadows at higher latitudes... or some other arrangment... for a targetted offset polar amplification of AGW especially and in particular perhaps avoiding the reduction in precipitation that can be caused by SW - radiation - based «GE» (although aerosols that actually absorb some SW in the troposphere while shielding the surface would have the worst effect in that way, I'd think)... strategic distribution of solar shading has been suggested with precipitation effects in mind, such as here... sorry, I don't have the link (I'm sure I saved it, just as Steve Fish would suggest — but where?).

Scientists have known for some time that there is this amplification effect, but almost all of the climate models we examined underestimated the impact — and they contained a pretty broad range of scenarios.

Global climate models have successfully predicted the rise in temperature as greenhouse gases increased, the cooling of the stratosphere as the troposphere warmed, polar amplification due the ice - albedo effect and other effects, greater increase in nighttime than in daytime temperatures, and the magnitude and duration of the cooling from the eruption of Mount Pinatubo.

During the Pleistocene - Holocene transition, one possible explanation to the amplification of the ghg - effect could have been the release of South Siberian European and North American (then) permafrost land - based carbon.

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).

If you just look at amplification of CO2's greenhouse effect by water vapor, the rise in temperature due to CO2 will result in a certain amount of additional water vapor.

(Amplification due to the albedo effect from sea ice will have its share of the pie, too.)

This mechanism allows him to not question any other mechanisms: not the posited amplifications of CO2's effect, not external mechanisms (solar changes), not long - term cloud / moisture effects or any other changes in a complex system, but rather to posit a mechanism that only recently kicked in and which can only affect the future in bad ways.

Should the water amplification mechanism of CO2's GHG effect be true, one would also expect to see an increase in the humidity, at altitude, at the same light flux.

As the ocean warms, more H2O (and CO2) will outgas, which will raise the specific humidity of the air thus leading to amplification of the GHG effect, and then spreading to land areas.

I then refer to the effect of superimposing feedbacks that are subject to observational confirmation, and which indicate fairly substantial amplification of the direct CO2 response.
