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 been suggested that ice sheets could be stabilized by reducing the lubrication effect of water below the ice sheet.
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.
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).
