Ice, Baby, Ice!

If humans manage to stick to the Paris agreement (very unlikely) of limiting global heating to 1.5 degrees Centigrade above Pre-Industrial levels, a half of the planet's glaciers will be lost. If the current track is continued to a 2.7 degree rise, 68% of glaciers will disappear (https://www.theguardian.com/environment/2023/jan/05/half-planets-glaciers-gone-2100-even-under-paris-15c-accord-data-finds). The planet has a lot of water but much of it is in the oceans. Fresh water is a surprisingly scarce commodity. Many Earthlings don't have a regular supply of drinking water. The loss of glaciers will exacerbate this problem. Glaciers are 'rivers of ice' that have traditionally released their fresh water, in a relatively controlled manner, over the seasons. Without them, agriculture is likely to fail in many regions of the planet.
