Sea ice reflects most of the sun's energy, he explained,
whereas the open ocean absorbs more energy, and thus the disappearance of sea ice triggers even more warming, in a positive -
feedback loop called
albedo.
In LGM simulations land
albedo changes are prescribed (at least in regards to ice sheets and altered topography due to sea level; there are
feedback land
albedo changes) so are a forcing,
whereas sea ice is determined interactively by the model climate, so is a
feedback in this framework.
The identified atmospheric
feedbacks including changes in planetary
albedo, in water vapour distribution and in meridional latent heat transport are all poorly represented in zonal energy balance model as the one used in [7]
whereas they appear to be of primary importance when focusing on ancient greenhouse climates.
