Define the snow-albedo positive feedback mechanism
The snow-albedo feedback is the mechanism when an increase in global surface air temperature causes snow and ice to melt in polar latitudes. This melting reduces the albedo (reflectivity) of the surface, allowing more solar energy to reach the surface, which further raises the temperature.
