The glaciers around Puncak Jaya lost nearly 80 percent of their area between 1936 and 2006 two - thirds of that loss has come since 1970.

Rising global temperatures have also made glaciers — ice masses that currently occupy nearly 10 percent of the world's total land area — increasingly unstable.

In 1950s only the most northerly glaciers appeared to be retreating, but a transition from advance to retreat appeared to move down the Antarctic Peninsula over a period of about 10 to 20 years, broadly in line with what we would expect if this was a consequence of the warming that has been measured in this area.

Global warming will also mean more forest fires; hurricanes hitting cities that are at present too far north of the equator to be affected by them; tropical diseases spreading beyond their present zones; the extinction of species unable to adapt to warmer temperatures; retreating glaciers and melting polar icecaps; and rising seas inundating coastal areas.

Evans said they expect to see seasonal changes in carbon dioxide, related to temperature; changes related to freshwater sources, such as glacier melt and stream outfalls; and changes connected to areas of large development.

Either the glaciers would have to flow into the ocean at unrealistic rates, or rapid melting would have to be triggered over a much larger area of the ice sheet than current evidence suggests.

The highlighted area shows a dense concentration of crevasses along one edge of the glacier.

While there is ample evidence of increasing fresh water contribution from melting glaciers and of an AMOC slow down since the 1930s the cold spot intensification last winter and this winter could also be caused by the extraordinarily intense low pressure areas that have slammed this region since last February and the intensification and northeastwards displacement of the subtropical Bermuda / Azores high.

Combined with melting from mountain glaciers and the Greenland Ice Sheet, this could result in flooding of low - lying areas of Earth over the next century.

A few large glaciers made up the majority of the glacierised area.

Ice - shelf structure seems to be important, with sutures between tributary glaciers resulting in weaker areas of thinner ice, which are susceptible to rifting [11].

We now see a world in which Siberia is considered to be the coldest area during NH winters, yet, Siberia appears to have been free of glaciers during the LGM from what little I've seen.

Further inland, the glaciers widen into a two - mile - thick reserve of ice covering an area the size of Texas.

As a general matter, yes, but AIUI the increasing height (depth) of the ice face is the key factor for accelerating retreat of these glaciers since it creates more surface area for the warm water to work on.

The pressures exerted from the interior of the glacier will force movement into those areas with the least resistance.

This means that all the energy going into the melting of sea ice, ice sheets and glaciers plus the warming of land and atmosphere is the tiny gap between the blue area and the red line.

Causes of erosion include wind, water (including rainfall and floods), the scouring action of glaciers, and the repeated cycles of freezing and thawing that often occur in some areas of the world.

The rapid shrinkage of glaciers around the Antarctic Peninsula, coupled with the potential for ice - shelf collapse and grounding line retreat, raises concerns for the future of the West Antarctic Ice Sheet, and this is an area of urgent current research [3].
