Sentences with phrase «albedo feedback under»
However, possible use of seasonal snow albedo feedback to evaluate snow albedo feedback under climate change conditions is of course dependent upon the realism of the correlation between the two feedbacks suggested by GCMs (Figure 8.16).

The three main criteria for a robust emergent constraint are satisfied: the physical mechanisms are well understood, the statistical relationship between the quantities of interest is strong, and uncertainties in the observed variations are weak, allowing Hall and Qu to constrain the snow - albedo feedback under global warming.
Zeng, N., and J.Yoon, 2009: Expansion of the world's deserts due to vegetation - albedo feedback under global warming, Geophys.
Model performance in reproducing the observed seasonal cycle of land snow cover may provide an indirect evaluation of the simulated snow - albedo feedback under climate change.

I am under the impression that it is driven by CO2 mediated ice - loss that generates albedo changes resulting in positive feedbacks that increase further melting.
Thus, the positive λSW of the CMIP5 ensemble average and the resulting energy accumulation by enhanced ASR under GHG forcing can be expected based only on the robust physics of the water vapor feedback and the surface albedo feedback in the absence of any changes in clouds... ``
Typical temperature reconstructions for the late Pliocene however [see one at the top of this story - 3.3 - 3.0 Ma] already show an Earth in which a warmer climatic state is indeed [through for instance ice albedo feedbacks] relatively strong around the poles, and (on average) weaker around the equator, exactly the pattern that is monitored under the current climate warming.
For example, the absence from AR5 of last January's Ramanathan paper indicating a large and very significant Albedo Loss feedback forcing can not be rectified until about 2019 under the current system of periodic IPCC reports advising the UNFCCC as to the climate predicament.
As for trading opinions, IMO you over-state the * global * efficacy of ice - albedo feedback and under - state the global efficacy of GHGs.
