Increasing Arctic Sea Ice Albedo Using Localized Reversible Geoengineering
Abstract The rising costs of climate change merit serious evaluation of potential climate restoration solutions. The highest rate of change in climate is observed in the Arctic where the summer ice is diminishing at an accelerated rate. The loss of Arctic sea ice increases radiative forcing and cont...
