Arctic coasts on the retreat - International studies describe current state of the Arctic coasts

[18. April 2011] 

The coastline in Arctic regions reacts to climate change with increased erosion and retreats by half a metre per year on average. This means substantial changes for Arctic ecosystems near the coast and the population living there.

Record depletion of Arctic ozone layer caused increased UV radiation in Scandinavia - Brief episodes of increased UV radiation may also occur over Central Europe

[05. April 2011] 

Over the past few days ozone-depleted air masses extended from the north pole to southern Scandinavia leading to higher than normal levels of ultraviolet (UV) radiation during sunny days in southern Finland. These air masses will move east over the next few days, covering parts of Russia and perhaps extend as far south as the Chinese/Russian border.

Large-scale assessment of the Arctic Ocean: significant increase in freshwater content since 1990s

[24. March 2011] 

The freshwater content of the upper Arctic Ocean has increased by about 20 percent since the 1990s. This corresponds to a rise of approx. 8,400 cubic kilometres and has the same magnitude as the volume of freshwater annually exported on average from this marine region in liquid or frozen form.

Arctic on the verge of record ozone loss - Arctic-wide measurements verify rapid depletion in recent days

[14. March 2011] 

Unusually low temperatures in the Arctic ozone layer have recently initiated massive ozone depletion. The Arctic appears to be heading for a record loss of this trace gas that protects the Earth’s surface against ultraviolet radiation from the sun.

New Interpretation of Antarctic Ice-Cores

[02. March 2011] 

Climate researchers at the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association (AWI) expand a prevalent theory regarding the development of ice ages. In the current issue of the journal “Nature” three physicists from AWI’s working group “Dynamics of the Palaeoclimate” present new calculations on the connection between natural insolation and long-term changes in global climate activity.
