Climate models indicate that the reduction of surface albedo caused by black-carbon contamination of snow contributes to global warming and near-worldwide melting of ice1,2. In this study, we generated and characterized pure and black-carbonladen snow in the laboratory and verified that black-carbon contamination appreciably reduces snow albedo at levels that have been found in natural settings1,3,4. Increasing the size of snow grains in our experiments decreased snow albedo and amplified the… CONTINUE READING
