What amount of ice is melting from the glaciers everyday?

Answer 1

Glaciers are not simple things to measure, and you really can't make generalizations about all glaciers in the world.

We tend to speak of "mass balance" when it comes to glaciers, because almost all glaciers both add mass through snowfall during much of the year, and they lose mass during the melt season in summer as the ice melts into water and drains off. It isn't always easy to determine whether a glacier is in net gain or net mass loss, but we have many methods of measuring, including many field methods as well as several clever types of remote sensing from the air and from satellites in space.

This is compounded by the complicated dynamics of glacier movement. Some glaciers have been found to be "surging" glaciers, meaning they may advance at incredibly fast rates (kilometers per year) before almost stopping entirely, and this works in cycles. You can see how it would then be difficult to get an average rate of melt. Also, there are both marine-terminating glaciers as well as those only on land, and their behavior depends on different factors.

In some places, mostly Scandinavia, glaciers are adding mass due to weather patterns that have shifted, for whatever reason (temporarily or permanently - probably the former), in the last decade or two. In most other places, they are losing mass. A new study found about 70% of Himalayan glaciers are losing mass, so even in one region some are gaining and some are losing. It depends on a lot of different factors, certainly not just temperature.

I suppose the question still hasn't been answered. There are numbers out there as far as volume loss and sea level rise per year, per decade, etc., but there is still considerable uncertainty...I don't think there's a point in repeating them. There is not uncertainty, however, in that we know that the majority, likely the great majority, are melting more than they're gaining. That is where I will leave it.

Answer 2

first of all that's a very stupid question and you know the answer, but when the temperature rises above 34 Fahrenheit at the location of the glacier than the glacier will melt, but slowly (unless the temp. keeps rising)

Answer 3

about 3 kgs each day
