Another cause of
reflectivity reduction is the exposure of bare ice once the snow melts.
The results showed no significant change in the quantity of black carbon deposited for the past 60 years or the quantity and mineralogical makeup of dust compared to the last 12,000 years, meaning that deposition of these light absorbing impurities is not a primary cause of
reflectivity reduction or surface melting in the dry snow zone.

Also, the clearinghouse reports that «heat gain
reductions... are significant only for sun - bathed surfaces» and that the «
reflectivity of the painted surface generally declines considerably with time.»
Anyone who accepts that sunlight falling on ice free waters which has less
reflectivity than sunlight falling on a large ice mass covering those waters and also accepts that this
reduction in albedo has a positive feedback effect, leading to further warming, can't help but opt for A or B, it seems to me.
• The
reduction of sea ice causes the surface
reflectivity to strongly decrease in the Arctic, which leads to decreases in shortwave radiation in the atmosphere and, thus, lower photo - dissociation rates of tropospheric gases.
