This report is about how climate change is affecting the cryosphere—those snow-capped mountain ranges, brilliant glaciers, and vast permafrost regions on which all of us depend. It lays out 14 specific measures we could take by 2030 to reduce short-lived climate pollutants and slow the melting of ice and snow that must stay frozen to keep oceans and global temperatures from rising even faster. Action to stabilize the cryosphere will also save lives now. By mitigating short-lived climate pollutants such as black carbon and methane, we will improve health in thousands of communities, many of them in the developing world.
