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…

Newly Discovered Methane Source in the Arctic: Ocean Surface Waters
24.04.2012
According to a multi-institutional study published in Nature Geoscience, areas in the Arctic Ocean appear to be emitting the potent greenhouse gas methane (CH4). As a greenhouse gas, methane is 20 times more powerful than carbon dioxide (CO2).

Scientists Advocate Moratorium on Fishing in Arctic
24.04.2012
In an open letter released by the Pew Environment Group, more that 2,000 scientists from 67 countries are encouraging calling for a moratorium on commercial fishing in the Arctic until more research can be done on the regions that were once covered by sea ice throughout the year.

Study Shows Increase in Atmospheric CO2 Helped End Last Ice Age
10.04.2012
Scientists have been able to reconstruct past temperatures using proxy methods such as reading ice cores, tree rings and sediment cores from the bottom of lakes and oceans. They have also been able to reconstruct past levels of the greenhouse gas carbon dioxide (CO2) in the atmosphere from air bubbles…

NRC Releases Synthesis of Reports on the State of the Polar Regions
04.04.2012
The US National Research Council (NRC) has just released a synthesis of reports from thousands of scientists from 60 countries who participated in research projects during the International Polar Year (IPY) 2007- 2008.

Arctic Sea Ice Reaches 2012 Winter Maximum
31.03.2012
Sea ice in the Arctic reached its maximum extent for the winter of 2011-2012 on 18 March, according to the National Snow and Ice Data Center (NSIDC). Total extent reached 15.24 million km2, the ninth lowest maximum sea ice extent on record.

Marine Mammals Face Increased Risk from Arctic Shipping, Say WCS and Alaska Native Groups
23.03.2012
According to conclusions from a workshop involving Alaska Native groups and the Wildlife Conservation Society, a rapid increase in shipping in the Arctic significantly increases risk posed to marine mammals and the local communities that rely on them. The workshop, held in Anchorage, Alaska 12-14 March, looked at potential impacts…
