One of the potentially most catastrophic effects of contemporary global warming would be the dramatic increase in sea levels as a result of the melting Greenland and Antarctic ice sheets. Even if all current emissions were immediately stopped, sea level rise could still occur because of locked-in warming (ICCI 2022).
One method to increase the albedo of individual glaciers already in use is to wrap them in reflective materials.
Increasing precipitation on a glacier would add to the glacier's mass, thereby directly countering the melting. Also, the snow that falls would increase glacial albedo, and thereby reduce the amount of absorbed energy.
It has been suggested that ice sheets could be stabilized by building physical structures that could artificially support and buttress them.
Several high mountain communities around the world have a long history of building barriers and other constructions that trap or hold meltwater by refreezing it (Nüsser et al. 2019b).
