Latest Climate of the Arctic Stories
WASHINGTON, Jan. 12, 2011 /PRNewswire-USNewswire/ -- Global surface temperatures in 2010 tied 2005 as the warmest on record, according to an analysis released Wednesday by researchers at NASA's Goddard Institute for Space Studies (GISS) in New York. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) The two years differed by less than 0.018 degrees Fahrenheit. The difference is smaller than the uncertainty in comparing the temperatures of recent years, putting them into a...
Record-breaking temperatures, extreme drought, stronger hurricanes and record rainfall are among the latest signs of climate change, scientists are warning. Weather patterns could become worse in the future if the world continues on its fossil-fuel consuming course, the scientists told AFP during a conference call Wednesday to discuss the year in global warming. Michael Mann, one of the leading scientists on the conference call, said he had just returned from a trip to Churchill, Manitoba, 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...
GREENBELT, Md., Sept. 1 /PRNewswire-USNewswire/ -- Operation IceBridge - a NASA airborne mission to observe changes in Earth's rapidly changing polar land ice and sea ice - is soon to embark on its fourth field season in October. The mission is now paralleled by a campaign to bring data to researchers as quickly as possible and to accelerate the analysis of those changes and how they may affect people and climate systems.

A new study of the High Arctic climate roughly 50 million years ago led by the University of Colorado at Boulder helps to explain how ancient alligators and giant tortoises were able to thrive on Ellesmere Island well above the Arctic Circle, even as they endured six months of darkness each year.The new study, which looked at temperatures during the early Eocene period 52 to 53 million years ago, also has implications for the impacts of future climate change as Arctic temperatures continue to...
NASA's first dedicated oceanographic field campaign goes to sea next week to take an up-close look at how changing conditions in the Arctic are affecting the ocean's chemistry and ecosystems that play a critical role in global climate change.The ICESCAPE mission, which stands for "Impacts of Climate on Ecosystems and Chemistry of the Arctic Pacific Environment," will investigate the impacts of climate change on the ecology and biogeochemistry of the Chukchi and Beaufort seas along...

NASA will hold a media teleconference at 1 p.m. EDT on Tuesday, June 8 to preview the agency's first dedicated oceanographic research voyage. During the mission, scientists will study changing Arctic climate and ice conditions affecting ocean ecosystems.The "Impacts of Climate on Ecosystems and Chemistry of the Arctic Pacific Environment" mission, or ICESCAPE, will investigate how climate change in the Arctic may be altering the ocean's ability to absorb carbon from the atmosphere....
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...
