Melting Arctic Uncovers Geologic Methane Seeps in Alaska and Greenland
23.05.2012
A study published in Nature Geoscience conducted by a team of researchers from the University of Alaska Fairbanks (UAF) and Florida State University has shown that melting permafrost and glaciers have the potential to release significant amounts of methane (CH4), a greenhouse gas 23 times more potent than carbon dioxide…

Research Provides New Insight into Carbon Cycle in Arctic Ocean
23.05.2012
A study conducted by scientists from the Woods Hole Oceanographic Institution (WHOI), the Institute of Ocean Sciences at Fisheries and Oceans Canada, the University of British Columbia and the Swiss Federal Institute of Technology has given greater insight into the processes by which carbon enters and is used in the…

Toxic Mercury Building up in Arctic Ocean
23.05.2012
According to a study published in Nature Geoscience, the discharge from circumpolar rivers is transporting more mercury into the Arctic Ocean marine environment than previously thought. Along with atmospheric fluctuations, river discharge from watersheds surrounding the Arctic Ocean, brings mercury into the region’s marine environment.

New Weak Point Found in Antarctic Ice Sheet
21.05.2012
Researchers from the Alfred Wengener Institute for Polar and Marine Science (AWI) and the UK’s Met Office Hadley Centre have found a weak point in the Antarctic Ice Sheet: the Filcher-Ronne Ice Shelf, which borders the Weddell Sea in East in Antarctica.

Analysis of Greenland Ice Sheet’s Dynamics Indicates Worst-Case Melt Scenario Unlikely
07.05.2012
A new study conducted by a team of researchers from the University of Washington and Ohio State University has been able to give a more comprehensive analysis of the ice dynamics of the Greenland Ice Sheet’s glaciers.

Sea Ice Loss Forcing Polar Bears to Swim Longer Distances, Says USGS Study
03.05.2012
With Arctic sea ice on the decline, polar bears must swim nonstop for hundreds of kilometres in order to find food, according to a USGS study published in the Canadian Journal of Zoology.

Arctic Sea Ice Loss Strongly Linked to Rise in Greenhouse Gasses
03.05.2012
A new study conducted by scientists from the Max Plank Institute for Meteorology in Germany shows a strong, physically plausible correlation between rising concentrations of greenhouse gases in the atmosphere and diminishing sea ice in the Arctic.

Ikaite Crystals Show Antarctica Was Affected by Recent Climate Fluctuations
03.05.2012
A new method of reconstructing past climates - which uses water locked inside ikaite crystals in ocean seabed sediment - indicates that the Medieval Warm Period (MWP) and the subsequent Little Ice Age (LIA) may have affected areas as far south as the Antarctic Peninsula.

Climate Change Altering Marine Habitats in Arctic Ocean
26.04.2012
Released at the IPY “From Knowledge to Action” conference in Montréal, a new study indicates that climate change is affecting biodiversity in the Arctic and posing “significant challenges” to the survival of marine life in the region.

Warm Ocean Water Melting Antarctic Ice Shelves from Below
26.04.2012
Results of a new multinational study published in Nature show that warming ocean water making itw way under ice shelves in Antarctica is a major cause of ice loss on the continent. Carried out by researchers from the British Antarctic Survey, Utrecht University, the University of California San Diego and…
