In general, a glacier is formed and maintained by a cycle of snow falling at high altitudes, melt occurring at lower altitudes and or discharge into the sea.

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.
The loss of ice in Greenland and the shrinking of glaciers in other parts of the Arctic currently contribute up to 40% of the average 3 mm global sea level rise per year. A number of studies suggest that Greenland could be a major contributor to a potential rise in sea levels of 0,5 to 1 meter by the end of the century.

There is a suggestion to use localized surface technologies to create artificial snow cover on mountain glaciers Oerlemans et al. (2017).
Krossfjorden lies within the Spitsbergen National Park in the Svalbard archipelago. The mountain formations in this area represent different geological periods and the site is recognized as an important monitoring station for climate variations. Lucky visitors to the area might witness the calving of ice into the sea from one of the five surrounding fjords.

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.
Mass loss from the Greenland ice sheet quadrupled over the past two decades, contributing a quarter of the observed global sea-level rise.

One method to increase the albedo of individual glaciers already in use is to wrap them in reflective materials.

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).

It covers about 98% of the Antarctic continent and is the largest single mass of ice on Earth.

It has been suggested that ice sheets could be stabilized by building physical structures that could artificially support and buttress them.

It has been suggested that ice sheets could be stabilized by reducing the lubrication effect of water below the ice sheet.
About 61% of all fresh water on Earth is held in the Antarctic ice sheet, an equivalent to 70 m of water in the world's oceans.

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).
Glaciers cover around 59% of Svalbard, which is made up of four islands, Spitsbergen, Nordaustlandet, Edgerøya and Barentsrøya. Many of the glaciers in this area are known to surge, meaning that for 100 years they can remain still and silent, only to suddenly and violently move, advancing from the upper area of the glacier towards the mouth.

Engineer Paul Klinkman has suggested increasing the water content around glaciers and ice sheets to increase precipitation over them (see Klinkman Solar Design, U2).
An ice shelf is a thick platform of ice that forms at the grounding line of a glacier, where the glacier meets the coastline.

With rising Arctic temperatures, there have been major changes in iceberg production rates from marine terminating glaciers. These icebergs drift into warmer sea waters where they will slowly melt.
The ice in glaciers has been under enormous pressure for eons. The compression eliminates air and reflective surfaces within the ice.

In 2019, an Indonesian design team came up with the idea of a submersible device that could take in sea water, desalinate it, and then have it freeze into a solid block they called a “new ice baby” (Griffiths, 2019).
