Sentences with phrase «glaciers retreat due»

In general, glaciers retreat due to a combination of rising temperatures and declining precipitation, but the temperature and precipitation records from the Alps indicated that glaciers should have continued advancing until around 1910.
As these glaciers retreat due to global warming (see Chapter 1), river flows are increased in the short term, but the contribution of glacier melt will gradually decrease over the next few decades.

He says: «However, as far as the mid-19th century is concerned, forcings due to GHG concentrations are insignificant so we are only left with natural forcings (or causes) as an explanation for glacier retreat
Since IPCC (2001) the cryosphere has undergone significant changes, such as the substantial retreat of arctic sea ice, especially in summer; the continued shrinking of mountain glaciers; the decrease in the extent of snow cover and seasonally frozen ground, particularly in spring; the earlier breakup of river and lake ice; and widespread thinning of antarctic ice shelves along the Amundsen Sea coast, indicating increased basal melting due to increased ocean heat fluxes in the cavities below the ice shelves.

Of course, other reasons could exist for glacier retreat (e.g. Kilimanjaro's glacier retreat is apparently due not to increased temperatures but rather to decreased participation — and perhaps human clearing of trees has a role in that!)
Two new studies conducted by researchers at NASA and the University of California, Irvine, have revealed that glaciers in West Antarctica are retreating at an unprecedented rate due to warm water circulating beneath the ice shelf.
27 January 2000: The Hektoria Glacier system is stable, but increased summer melting from climate warming in the 1980s and 1990s affected the glacier system in two ways: (1) a seasonal speedup from summer melt water percolating through the glacier ice to its base, and (2) initial retreat of the Larsen Ice Shelf due to the effects of melt ponds (downstream from this image).
During the 1984 - 1994 period glacier retreat rates have increased substantially due to negative annual balances (Pelto, 1993).
This can be affected by warming temperatures, but also by changes in snowfall, increases in solar radiation absorption due to a decrease in cloud cover, and increases in the water vapor content of air near the earth's surface.2, 14,15,16,17 In Cordillera Blanca, Peru, for example, one study of glacier retreat between 1930 and 1950 linked the retreat to a decline in cloud cover and precipitation.18
Changes occurring due to glacier retreat have been observed in the Lewis Glacier Basin.
The retreat of Greenland's glaciers has been largely due to intruding warm waters driven by changes in natural ocean oscillations.
Some possible effects of global warming are the inundation of low - lying islands due to rising sea levels, increased frequency of severe storms and the retreat of glaciers and icecaps.
Between 1913 and 1945 the rate of retreat for the Sperry glacier was 10 times faster [due to drought] than rate of retreat since 1979.

There are many other references dating from this period available from the Alps: records of advancing snow and ice burying silver and gold mines, alpine villages, farms and pastures being abandoned due to colder climate, even physical evidence recovered today under retreating glaciers.
The pro-glacial lake is due to massive retreat of the glacier in recent decades.
Retreating glaciers = global warming, advancing glaciers = more snow due to global warming.
