Glaciers (CLIM 007) - Assessment published Nov 2012
-
The vast majority of glaciers in the European glacial regions are in retreat. Glaciers in the European Alps have lost approximately two thirds of their volume since 1850, with clear acceleration since the 1980s.
Glacier retreat is expected to continue in the future. The volume of European glaciers has been estimated to decline between 22 and 66 % compared to the current situation by 2100 under a business-as-usual emission scenario.
Glacier retreat contributes to sea-level rise and it affects freshwater supply and run off regimes, river navigation, irrigation and power generation. It may also cause natural hazards and damage to infrastructure.

Glaciers (CLIM 007) - Assessment published Sep 2008
-
The vast majority of glaciers in the European glacial regions are in retreat. Since 1850, glaciers in the European Alps have lost approximately two thirds of their volume, with clear acceleration since the 1980s. Glacier retreat is projected to continue. A 3 o C increase in average summer air temperature could reduce the existing glacier cover of the European Alps by some 80 %. With continuing climate change nearly all the smaller glaciers and one third of the overall glacier area in Norway are projected to disappear by 2100. Glacier retreat has serious consequences for river flow. It affects freshwater supply, river navigation, irrigation and power generation. It could cause natural hazards and damage to infrastructure.

Living with Climate change
-
Global warming is happening. Temperatures have already risen by 0.76 degrees since the industrial revolution and are projected to rise further by 1.8 - 4 degrees by the end of the century. The last time climate change happened at this pace was 125,000 years ago and led to a 4-6 metre sea level rise.
Global warming at the upper end of the scale predicted by the Intergovernmental Panel on Climate Change would have catastrophic consequences for Europe. Up to 30% of plant, animal and bird species would be wiped out and the threat of natural disasters such as landslides, floods and mudslides would increase significantly.

Projected changes in the volume of all mountain glaciers and ice caps in the European glaciated regions
-
This figure shows the projected volume (in cubic km) for 2001–2100 of all mountain glaciers and ice caps in the European glaciated regions derived using a mass balance model driven with temperature and precipitation scenarios from 10 GCMs. European Alps (top left), Scandinavia (top right), Iceland (bottom left), Svalbard (bottom right).

Rising snowline in the Alps
-
(This video has no audio.)
It is estimated that, as global warming proceeds, regions currently receiving snowfall will increasingly receive precipitation in the form of rain. For every 1ºC increase in temperature, the snowline rises by about 150 metres. As a result, less snow will accumulate at low elevations. As a consequence, nearly half of all ski resorts in Switzerland, and even more in Germany, Austria and the Pyrenees, will face difficulties in attracting tourists and winter sport enthusiasts in the future.

Understanding climate change — key message 5
-
The vast majority of glaciers in Europe are in retreat. Glaciers in the Alps lost about two-thirds of their volume between 1850 and 2009. The glacierised area in the Alps is projected to decrease to about one-third of the present area for a further rise in Alpine summer temperature of 2 °C.

Understanding climate change — SOER 2010 thematic assessment
-
Average global air and ocean temperatures are rising, leading to the melting of snow and ice
and rising global mean sea level. Ocean acidification results from higher CO2 concentrations.
With unabated greenhouse gas emissions, climate change could lead to an increasing risk of
irreversible shifts in the climate system with potentially serious consequences. Temperature
rises of more than 1.5–2 °C above pre-industrial levels are likely to cause major societal and
environmental disruptions in many regions. The atmospheric CO2 concentration needs to be
stabilised at 350–400 parts per million (ppm) in order to have a 50 % chance of limiting global
mean temperature increase to 2 °C above pre-industrial levels (according to the IPCC in 2007,
and confirmed by later scientific insights).
