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).
It has recently been suggested that hollow glass microspheres (HGM, see also see sea ice albedo increase) could be used to increase the albedo of mountain glaciers and thereby slow their melt.
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.
Engineer Paul Klinkman has suggested increasing the water content around glaciers and ice sheets to increase precipitation over them (see Klinkman Solar Design, U2).
