Understanding climate change — key message 4
-
Observed global mean sea level rise has accelerated over the past 15 years. From 2002 to 2009 the contributions of the Greenland and West Antarctic ice sheets to sea level rise increased. In 2007 the IPCC projected a sea level rise of 0.18 to 0.59 m above the 1990 level by 2100 excluding the effects of dynamic ice sheet processes. Recent projections show a maximum increase of about 1.0 m by 2100, while higher values up to 2.0 m cannot be excluded.

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.

Recent research suggests that several key components of the climate system could undergo irreversible change at significantly lower levels of global temperature increase than previously assessed. The most important of these “tipping elements” for Europe are the Greenland ice sheet, Alpine glaciers, and Arctic sea ice.

The EU emitted close to 5 billion tonnes (Gt) of CO2-equivalents in 2008. It contributes today around 12 % of annual global anthropogenic direct greenhouse gas emissions.

Modelled remains of the glacier cover in the European Alps for an increase in average summer air temperature of 1 to 5 oC
-
Modelled remains of the Alpine glacierisation (climatic accumulation area) according to an increase in summer air temperature of +1 to +5 °C. The total of 100% refers to the ice cover of the reference period (1971–90). The 100%-marks of the other lines refer to the fraction of glacierisation of the corresponding Alpine country. Reading example: A rise in summer air temperature of 3 °C would reduce the Alpine ice cover (red curve) to about 20% of the glacier cover of the reference period (1971–90). The corresponding glacier remains of Switzerland (blue, dashed line) amounts to about 30%, whereas in Austria (black, dashed line) only about 7% of the glacier cover of the reference period is left.
