- 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 84 % compared to the current situation by 2100 under a moderate greenhouse gas forcing scenario and between 38 and 89% under a high forcing scenario.
- Glacier retreat has contributed to global sea-level rise with about 0.8 mm per year in 2005-2009. It also affects freshwater supply and run off regimes, river navigation, irrigation and power generation. Furthermore it may cause natural hazards and damage to infrastructure.
