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).
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).
Engineer Paul Klinkman has suggested increasing the water content around glaciers and ice sheets to increase precipitation over them (see Klinkman Solar Design, U2).
One method to increase the albedo of individual glaciers already in use is to wrap them in reflective materials.
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.
