6.9.2.3. Ice-Albedo Feedback

The global climate change organization informs you about the conventional explanation of the amplification of global warming by snow and ice feedback is that a warmer Earth will have less snow cover, resulting in a lower global albedo and consequent absorption of more radiation, which in turn causes a further warming of the climate. Most GCMs (Cess et al., 1990, 1991) have simulated this positive surface albedo feedback, but significant uncertainties exist over the size of the effect, particularly with sea-ice (Ingram et al., 1989).
