Scientists at the National Snow and Ice Data Center (NSIDC) in Colorado estimate that if global warming continues even at a moderate pace, a third of the earth's permafrost will be gone by 2200. A study released Wednesday, based on UN Intergovernmental Panel on Climate Change (IPCC) scenarios, warns that global warming could cause up to 60 percent of the world's permafrost to thaw by 2200 releasing huge amounts of carbon into the atmosphere increasing the rate of climate change, AFP is...

A NASA analysis of satellite data has quantified, for the first time, the amount of older and thicker "multiyear" sea ice lost from the Arctic Ocean due to melting. Since the start of the satellite record in 1979, scientists have observed the continued disappearance of older "multiyear" sea ice that survives more than one summer melt season. Some scientists suspected that this loss was due entirely to wind pushing the ice out of the Arctic Basin -- a process that scientists refer to as...

Climate scientists at the U.S. National Oceanic and Atmospheric Administration (NOAA) reported Thursday that Arctic temperatures are on the rise again. The sea ice extent has also fallen to one of the lowest levels on record, according to NOAA's annual Arctic report card, which was prepared this year by 69 researchers in eight countries. "A return to previous Arctic conditions is unlikely," wrote the scientists in the report. "Record temperatures across Canadian Arctic and Greenland, a...

The likelihood of summer Arctic ice cover disappearing within the next few years is unlikely, according to researchers from the University of Colorado at Boulder, though the minimum of ice found in the ocean has dipped to its third lowest levels since 1979. According to a press release, scientists at the university's National Snow and Ice Data Center (NSIDC) found that the Arctic ice extent dropped to 1.84 million square miles at its lowest point, on September 10. That is 630,000 square miles...

North America, Europe and eastern Asia could see more cold, moist and snowy winters much like the one that just passed, according to one top scientist. James Overland of the US National Oceanic and Atmospheric Administration (NOAA) told the AFP news agency, "Cold and snowy winters will be the rule rather than the exception." It may seem counter-intuitive, but warmer Arctic climates caused by climate change influence air pressure at the North Pole, which shifts wind patterns in such a...

Melting sea ice has been shown to be a major cause of warming in the Arctic, according to a University of Melbourne, Australia study. Findings published in Nature today reveal the rapid melting of sea ice has dramatically increased the levels of warming in the region in the last two decades. Lead author Dr James Screen of the School of Earth Sciences at the University of Melbourne says the increased Arctic warming was due to a positive feedback between sea ice melting and atmospheric...

The U.S. National Snow and Ice Data Center reports that the extent of sea ice over the Arctic Ocean grew until the last day of March, which is the latest the annual melting season has begun in 31 years of satellite records. The center said in a statement on Wednesday that cold weather and winds from the north over the Bering Sea and Barents Sea meant the area of ocean covered by ice expanded through last month.  That is two days later than in 1999, the previous latest start to a melting...

Bears changing habitat in response to sea ice conditions A long-term study showing the changes in habitat associations of polar bears in response to sea ice conditions in the southern Beaufort Sea has implications for polar bear management in Alaska. Karyn Rode, a polar bear biologist with the U.S. Fish and Wildlife Service in Anchorage, Alaska and one of the study's authors, says data collected between 1979 and 2005 show that polar bears in the region are occurring more frequently on land...

In an annual update on the condition of the planet's Arctic zones, Richard Spinrad, chief of research at the National Oceanic and Atmospheric Administration, warned that the affects of global warming may be wreaking havoc on the planet's built-in thermostat. According to report from Spinrad's team, average temperatures in and around the North Pole continue to climb while sea ice and glaciers are melting rapidly, disrupting both marine and terrestrial ecosystems. In a press briefing on the...

New study shows that Arctic has potential to alter Earth's climate In a new study in the journal Ecological Monographs, ecologists estimate that Arctic lands and oceans are responsible for up to 25 percent of the global net sink of atmospheric carbon dioxide. Under current predictions of global warming, this Arctic sink could be diminished or reversed, potentially accelerating predicted rates of climate change. In their review paper, David McGuire of the U.S. Geological Survey and the...
