Russian scientists encircled by 10 adult
polar bears for two weeks
at Troynoy Island in the Kara Sea

Russian scientists have driven away polar bears that besieged their weather station on an island in the Arctic Ocean for two weeks.A nearby ship was able to reach the island and supply the scientists with dogs and flares to scare off the bears.Five scientists based at the weather station on Troynoy island, in the Kara Sea north of Siberia, were encircled by 10 adult bears and some cubs read more

University of Delaware scientists report
data from under Greenland's
Saint Pettermann Glacier

Based on data from the first University of Delaware (UD) ocean sensors deployed under Greenland's Petermann Glacier, UD researchers report that the floating ice shelf is strongly coupled, or tied, to the ocean below and to the adjacent Nares Strait. Warming temperatures recorded at the deepest ocean sensors match data from Nares Strait, which connects the Arctic and Atlantic oceans.

Melting sea ice may be speeding
nature's clock in the Arctic

Spring is coming sooner to some plant species in the low Arctic of Greenland, while other species are delaying their emergence amid warming winters. The changes are associated with diminishing sea ice cover, according to a study published in the journal Biology Letters and led by the University of California, more

Unrelenting global warming sends sea ice
to record low, as scientists feel heat, too

Compared to the average from 1981 to 2010, the area of ice missing in the Arctic was about the size of Texas and Arizona combined; in the Antarctic, it was bigger than Alaska, according to the NSIDC.Temperatures in the Arctic were about 9 degrees Fahrenheit above average throughout November and December, with peak readings soaring to 50 degrees above the long-term average around Christmas, when the North Pole warmed above freezing, a mark rarely seen outside of summer. read more
