Long-term Data Reveal Deep Greenland Sea Warming Faster Than The Global Ocean
2013-09-25 12:53:48

Alfred Wegener Institute Recent warming of the Greenland Sea Deep Water is about ten times higher than warming rates estimated for the global ocean. Scientists from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research recently published these findings in the journal Geophysical Research Letters. For their study, they analyzed  temperature data from 1950 to 2010 in the abyssal Greenland Sea, which is an ocean area located just to the south of the Arctic Ocean....

Understanding A Century Of Human Impact On Arctic Climate
2013-09-12 13:02:22

Desert Research Institute The Arctic is the most rapidly warming region of the globe, but warming has not been uniform and the drivers behind this warming not fully understood even during the 20th century. A new study authored by Canadian and American investigators and published in Scientific Reports, a primary research publication from the publishers of Nature, suggests that both anthropogenic and natural factors – specifically sulphate aerosols from industrial activity and volcanic...

April Flowers for redOrbit.com - Your Universe Online An international team of scientists, led by Julie Brigham-Grette of the University of Amherst, has analyzed the longest continental sediment core ever collected in the Arctic to provide “absolutely new knowledge” of Arctic climate from 2.2 million to 3.6 million years ago. "While existing geologic records from the Arctic contain important hints about this time period, what we are presenting is the most continuous archive...

Researchers Predict Sea Ice-Free Arctic Summers By 2050
2013-04-13 08:18:46

April Flowers for redOrbit.com — Your Universe Online The question of ice-free summers in the Arctic, for most scientists, is not "if," but "when." A new study by two National Oceanic and Atmospheric Administration (NOAA) scientists says that "when" is coming sooner than many thought. Already, the Arctic has experienced a loss of thick, multi-year ice, with last September´s extent being less than half the average of 1979-2000. The scientists, James Overland...

Greenland's 2012 Record Ice Melt Due To Thin Cloud Cover
2013-04-04 11:15:46

April Flowers for redOrbit.com - Your Universe Online Global sea levels would rise by 24 feet if the sheet of ice covering Greenland were to melt in its entirety tomorrow. But it is very unlikely that nearly two million cubic miles of ice will wash into the ocean overnight. Researchers have been tracking increasing melt rates since 1979. Last summer the melt was so extensive that ice core records show similar events only about once every 150 years over the last four millennia. "In...

Urine Of The Rock Hyrax Can Give Past Climate Clues
2013-02-18 08:40:23

Brett Smith for redOrbit.com - Your Universe Online Not cleaning a kitty´s litter box could be a disgusting thought for cat owners, but for Brian Chase of Montpellier University in France – layers of dried urine can reveal exciting new details about an environment as they stack up year after year and generation after generation. Instead of learning about the historical habitat of the common housecat, Chase and his colleagues from the European Research Council analyzed layers...

Snow Cover Worldwide Is At Record Lows
2012-12-04 07:25:37

April Flowers for redOrbit.com - Your Universe Online A new European Space Agency (ESA) study of snow cover observed by satellites reveals record lows in Eurasia for June each year since 2008. Three of the past five years have seen record low cover in North America, as well. Since satellite observations began some 45 years ago, this is the lowest June snow extent on record. Snow cover in June is falling faster than climate models have predicted. It is even disappearing faster than...

Arctic Climate Project Looking For Citizen Scientists
2012-10-25 04:06:11

Lee Rannals for redOrbit.com - Your Universe Online The National Oceanic and Atmospheric Administration (NOAA) is asking citizen scientists to come together to help reconstruct the historical climate of the Arctic. NOAA is teaming up with National Archives and Records Administration and Zooniverse, a citizen science web portal, to find volunteers to transcribe a newly digitized set of ship logs dating back to 1850. The ship logs are from the U.S. Navy, Coast Guard and Revenue Cutter...

The extent of the sea ice covering the Arctic Ocean has shrunk. According to scientists from NASA and the NASA-supported National Snow and Ice Data Center (NSIDC) in Boulder, Colo., the amount is the smallest size ever observed in the three decades since consistent satellite observations of the polar cap began. NASA and NSIDC scientists will host a media teleconference at 3 p.m. EDT, today, to discuss this new record low for summertime Arctic sea ice cover. The extent of Arctic sea ice...
