rCLWhile glaciers worldwide are said to be shrinking due to global
warming, there are a number of exceptions. Some are growing suddenly at extreme speeds, extending up to 100 times faster than usual.rCY
rCLThe reported sudden advances are said to be triggered by unstable mechanical conditions inside or at the base of the glacier. For example, meltwater can act as a lubricant, causing the ice to slide. The rapid movement can cause massive amounts of ice to become unstable and break off.rCY
rCLMoreover, the advancing ice masses can block valleys, causing lakes to form behind them. If these natural dams burst later, devastating flood
waves hit lower-lying regions.rCY
This is not entirely incorrect. How odd.
But a more important mechanism is this: when a glacier extends into a
high and very cold region, that region supplies very little new ice, as precipitation is low. A small amount of warming may increase the precipitation in this area far more than it increases the melting in the
rest of the glacier, resulting in net growth and accelerated flow of the glacier.
Many examples of this have been observed in real life.
In fact, in some warmish periods of the current ice age, parts of the
east Antarctic ice sheet actually thickened for this very reason. Local temperatures went from being so far below zero that snow was rare, to
only a few degrees below, with a substantial amount more snow.
But alas, the vast majority of glaciers are shrinking.
We are all going to die.
Over the millennia we have naturally crafted our civilization to profit
from the climate as it was. Any change will thus have a tendency to be
for the worse, though exceptions abound.
Thus one place that relied on glacial meltwater in summer finds it has
to make do with far less, while another place has too much. Even if the
net change in water over the two sites is zero, the net effect is negative.
