WebAn increase in surface albedo can result in a negative radiative forcing, while detrimental effects such as an increase in atmospheric CO 2 concentrations raises radiative forcing. [1] Intuitively, negative radiative forcing decreases net absorbed energy from the sun, and results in lower surface temperatures at equilibrium. ... Albedo is not directly dependent on illumination because changing the amount of incoming light proportionally changes the amount of reflected light, except in circumstances where a change in illumination induces a change in the Earth's surface at that location (e.g. through melting of reflective ice). That said, albedo and illumination both vary by latitude. Albedo is highest near the poles and low… WebDec 18, 2014 · The summer sea ice is almost half what is used to be, exposing more ocean surface. The consequence is a change in the albedo due to a decrease in the Earth’s ability to reflect energy and an increase in its ability to absorb it. Modeling and estimates of albedo change have previously been used to access the impact of decreased sea ice on albedo. openmbee github
