Model shows polar ice caps can recover from warmer climate-induced melting
A growing body of recent research indicates that, in Earth's warming climate, there is no "tipping point," or threshold warm temperature, beyond which polar sea ice cannot recover if temperatures come back down. New University ...
Ethane levels yield information about changes in greenhouse gas emissions
Recent data from NSF-funded research in both Greenland and Antarctica demonstrate that fossil-fuel related emissions of both methane and ethane, two of the most abundant hydrocarbons in the atmosphere, declined ...
Polar climate change may lead to ecological change
(PhysOrg.com) -- Ice and frozen ground at the North and South Poles are affected by climate change induced warming, but the consequences of thawing at each pole differ due to the geography and geology, according to a Penn ...
Tohoku tsunami created icebergs in Antarctica
A NASA scientist and her colleagues were able to observe for the first time the power of an earthquake and tsunami to break off large icebergs a hemisphere away.
Mars' northern polar regions in transition
A newly released image from ESA's Mars Express shows the north pole of Mars during the red planet's summer solstice. All the carbon dioxide ice has gone, leaving just a bright cap of water ice.
Arctic ice cap near 2007 record minimum: Russia
The polar ice cap in the Arctic has melted to near its 2007 record minimum level and in some areas is 50 percent smaller than average, Russia's environmental monitoring agency said Thursday.
Long-distance swims may cause polar bear problems
Polar bears forced to swim longer distances because of diminished sea ice off Alaska's coast may be paying a price in lost cubs or precious calories, according to a study by the U.S. Geological Survey.
