Graph of the Day: Change in Northern Hemisphere Cryospheric Climate Forcing, 1979-2008

Caption by Holli Riebeek24 February 2011 How could melting ice thousands of miles away possibly affect you? A recent study published in Nature Geoscience provides one answer to that question. Mark Flanner at the University of Michigan and his collaborators used satellite data to measure how much changes in snow and ice in the Northern […]

Video: Greenland’s glaciers double in speed

February 21, 2011 (PhysOrg) – The contribution of Greenland to global sea level change and the mapping of previously unknown basins and mountains beneath the Antarctic Ice Sheet are highlighted in a new film released by Cambridge University this morning. The work of glaciologist Professor Julian Dowdeswell, Director of Cambridge University’s Scott Polar Research Institute, […]

Graph of the Day: Carbon Emission from Arctic Permafrost Thaw, Projected to 2200

Contact: Katherine Leitzell, NSIDC Communication, leitzell@nsidc.org16 February 2011 One- to two-thirds of Earth’s permafrost will disappear by 2200, unleashing vast quantities of carbon into the atmosphere, says a study by researchers at the Cooperative Institute for Research in Environmental Sciences (CIRES) National Snow and Ice Data Center (NSIDC). “The amount of carbon released is equivalent […]

Climate change keenly felt in Alaska’s national parks – ‘We used to build with a sense of permanence’

By Yereth Rosen; editing by Steve Gorman and Greg McCuneSat Feb 12, 2011 12:43pm EST ANCHORAGE, Alaska (Reuters) – Thawing permafrost is triggering mudslides onto a key road traveled by busloads of sightseers. Tall bushes newly sprouted on the tundra are blocking panoramic views. And glaciers are receding from convenient viewing areas, while their rapid […]

Researchers warn Arctic fishing under-reported

By Allan Dowd; editing by Rob WilsonVANCOUVER | Fri Feb 4, 2011 6:03pm EST (Reuters) – The amount of fish caught in the Arctic has been dramatically under-reported for decades, making the northern ocean environment appear far more pristine than it really is, according to a new study. An estimated 950,000 tonnes of fish were […]

Graph of the Day: Temperature Reconstructions of Eastern Fram Strait Seawater Over the Past ~2100 Years

Planktic foraminiferal data and temperature reconstructions of upper Atlantic Water in the eastern Fram Strait over the past ~2100 years from sediment core MSM5/5-712-1. Thin lines are raw data, bold lines are three-point running means. Black triangles on the age scale mark calibrated accelerator mass spectrometry 14C ages. (A) Fluxes of polar and subpolar planktic […]

Alaska seeing impact of climate change in its infrastructure, villages – ‘Many years ago this would have been unheard of’

By Molly Rettig, Fairbanks Daily News MinerJan 30, 2011 FAIRBANKS — Climate change has already begun to make life difficult for state transportation managers. And they expect it to become a bigger and more expensive challenge if warming trends continue as predicted. “With over 6,600 miles of coastline and 80 percent of the state underlaid […]

Graph of the Day: North America Temperature Anomalies, 9-16 January 2011

Caption by Michon ScottJanuary 26, 2011 Snow fell in the U.S. Deep South, severe storms battered the East Coast, and International Falls, Minnesota, set a new temperature record: -46 degrees Fahrenheit (-43 degrees Celsius) on January 21. But in areas north of the United States and southern Canada, temperatures were above normal. In fact, unusual […]

Arctic current warmer than for 2,000 years: study

By Alister Doyle, Environment Correspondent; editing by Ralph BoultonFri Jan 28, 2011 5:33am EST OSLO (Reuters) – A North Atlantic current flowing into the Arctic Ocean is warmer than for at least 2,000 years in a sign that global warming is likely to bring ice-free seas around the North Pole in summers, a study showed. […]

Graph of the Day: Anomaly Map of Greenland Melting Days for 2010

Anomaly map of Greenland melting days for 2010 derived from passive microwave data. Hatched regions indicate where MAR-simulated meltwater production exceeds the mean by at least two standard deviations. Abstract: Analyses of remote sensing data, surface observations and output from a regional atmosphere model point to new records in 2010 for surface melt and albedo, […]
