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...

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 Alaska's...

PASADENA, Calif., May 26 /PRNewswire-USNewswire/ -- Data from NASA's Mars Reconnaissance Orbiter (MRO) have helped scientists solve a pair of mysteries dating back four decades and provided new information about climate change on the Red Planet. (Logo: http://www.newscom.com/cgi-bin/prnh/20081007/38461LOGO) The Shallow Radar, or SHARAD, instrument aboard MRO revealed subsurface geology allowing scientists to reconstruct the formation of a large chasm and a series of spiral troughs on...

Scientists have reconstructed the formation of two curious features in the northern ice cap of Mars"”a chasm larger than the Grand Canyon and a series of spiral troughs"”solving a pair of mysteries dating back four decades while finding new evidence of climate change on Mars. In a pair of papers to be published in the journal Nature on May 27, Jack Holt and Isaac Smith of The University of Texas at Austin's Institute for Geophysics and their colleagues describe how they used radar...

As ESA's Mission Scientist for CryoSat, Mark Drinkwater's role in supporting the preparation of the mission has been to ensure that the satellite and data processing systems are compatible with achieving the mission's objectives of deriving accurate measurements of ice-thickness change. Mark Drinkwater, a British national, trained as a geophysicist and performed early pioneering research in the use of altimeter measurements over polar ice. He currently heads the Mission Science Division at...

The launch of ESA's CryoSat-2 satellite from the Baikonur Cosmodrome in Kazakhstan, scheduled for February 25, has been delayed due to a concern related to the second stage steering engine of the Dnepr launcher. Although the fuel supply of the second stage engine should be sufficient to get CryoSat into orbit, the fuel reserve is not as large as they would like it to be, according to the Ukrainian company Yuzhnoye, who developed and is responsible for the launcher. The situation is being...

A U.S. government agency predicted the melting of the polar ice cap in the year 2030. However, climate guru Al Gore said at the U.N. climate conference on Monday that new computer modeling indicates this could happen as soon as 2014. One U.S. government scientist on Monday said the new prediction was too severe, but other researchers have previously projected a quicker end than 2030 to the Arctic summer ice cap. Former U.S. Vice President Gore said, "It is hard to capture the astonishment...

A NASA plane, outfitted with lasers and ground-penetrating radar, made it first flight over Antarctica in hopes of better understanding how melting ice could swamp the planet. On a mission to fly as low as 1,000 feet (300 meters) over the icy continent, the DC-8 left for an 11 hour trip out of Punta Arenas, Chile on Friday. Their goal: to understand just how warm ocean currents may be pulling the ice sheets seaward, melting their undersides. According to a study published in the journal...

A team of researchers report that the Arctic ice cap could be non-existent during the summer months 20 to 30 years from now. Pen Hadow led the Catlin Arctic Survey team that explored the Arctic ice cap for 73 days. The team took more than 6,000 measurements during March and May in order to reach their conclusions on the condition of the Arctic ice cap. They traveled 290 miles, beginning in northern Canada, documenting ice thickness, density and depth. Based on their observations, the team...

NASA will hold a media teleconference at 11:30 a.m. EDT on Thursday, Oct. 8, to preview the agency's largest airborne research effort ever to study Antarctic ice sheets, ice shelves and sea ice. The flights are part of NASA's Operation Ice Bridge, a six-year airborne campaign to each of Earth's polar regions that will extend and expand NASA's multi-year record of space-based observations of ice conditions. Advancing scientific understanding of the behavior of polar ice is needed to improve...
