Study finds high melt rates on Antarctica's most stable ice shelf

Thu, 01/14/2016 - 15:30
A new study measured a melt rate that is 25 times higher than expected on one part of the Ross Ice Shelf. The study suggests that high, localized melt rates such as this one on Antarctica's largest and most stable ice shelf are normal and keep Antarctica's ice sheets in balance.

Soil frost affects greenhouse gas emissions in the Arctic

Thu, 01/14/2016 - 10:08
Soil frost is a nearly universal process in the Arctic. In a recent dissertation, it is shown that the frequency and extent of soil frost is important for the release of the greenhouse gas carbon dioxide from arctic soil.

Maximizing sea life's ability to reduce atmospheric carbon may help combat climate change

Wed, 01/13/2016 - 15:24
New research on West Antarctic seabed life reveals that the remote region of the South Orkney Islands is a carbon sink hotspot. The findings suggest that this recently designated (and world's first) entirely high seas marine protected area may be a powerful natural ally in combating rising carbon dioxide as sea ice melts.

Human-made climate change suppresses the next ice age

Wed, 01/13/2016 - 15:07
Humanity has become a geological force that is able to suppress the beginning of the next ice age, a study shows. Cracking the code of glacial inception, scientists have found the relation of insolation and carbon dioxide concentration in the atmosphere to be the key criterion to explain the last eight glacial cycles in Earth history.

Ice sheets may be hiding vast reservoirs of powerful greenhouse gas

Wed, 01/13/2016 - 12:28
Ice sheets may be containing vast reservoirs of methane, adding a new concern regarding rapid ice sheet retreat, report scientists. This is the first comprehensive study that shows that there is a third process that can create, contain and maintain large amounts of gas hydrates: ice sheets.

Mountains west of Boulder continue to lose ice as climate warms

Tue, 01/12/2016 - 11:55
New research indicates an ongoing loss of ice on Niwot Ridge and the adjacent Green Lakes Valley in the high mountains west of Boulder is likely to progress as the climate continues to warm.

Greenland ice sheet melts more when it's cloudy

Tue, 01/12/2016 - 11:48
Clouds play a bigger role in the melting of the Greenland ice sheet than was previously assumed. Compared to clear skies, clouds enhance the meltwater runoff by a third, an international team of researchers has discovered.

Optimized arctic observations for improving weather forecast in the northern sea route

Fri, 01/08/2016 - 07:34
The Northern Sea Route could be an attractive shipping route during Arctic ice-free periods; however, the decline in sea-ice extent could also cause severe weather phenomena, which could disturb ship navigation in turn. The sparse observational network over the Arctic Ocean makes weather and sea-ice forecasts less accurate and increases uncertainties. However, a new article suggests that the quality of weather and sea-ice forecasts can be improved by optimizing the Arctic-observing network.

In Arctic winter, marine creatures migrate by the light of the moon

Thu, 01/07/2016 - 13:04
A few months ago, researchers reported the surprising discovery that marine creatures living in one Arctic fjord keep busy through the permanently dark and frigid winter months. Now, a report extends this activity to the whole of the Arctic. They also find that, in the absence of any sunlight, it's the moon that drives the vertical migrations of tiny marine animals.
