Autonomous vehicle developed by the University of Washington is an element of Arctic Observing Network, an International Polar Year research priority An intelligent, ocean-going glider has spent six months on a record-breaking deployment to sample the icy waters off western Greenland. The samples will contribute to the longest continuous measurement of Arctic currents that help to drive ocean circulation and regulate global seawater temperatures. The 49-kilogram (110-pound) seaglider,...

WASHINGTON, April 6 /PRNewswire-USNewswire/ -- The latest Arctic sea ice data from NASA and the National Snow and Ice Data Center show that the decade-long trend of shrinking sea ice cover is continuing. New evidence from satellite observations also shows that the ice cap is thinning as well. (Logo: http://www.newscom.com/cgi-bin/prnh/20081007/38461LOGO) Arctic sea ice works like an air conditioner for the global climate system. Ice naturally cools air and water masses, plays a key role in...

According to new analysis, arctic sea ice is melting so fast that the majority of it could be gone within the next 30 years.  The forecast is based on analysis generated using computer models of weather and climate.If the white ice melts, it will be replaced with dark ocean surface that will absorb sunlight. This will then speed up the global warming process.The findings increase concern about global warming, a problem that has become a focus of the G20 discussions under way in...

Arctic reindeer herders are facing the challenges of adapting to climate change as a warmer Arctic climate makes it harder for herds to find food and navigate. To help them adapt, the ESA-backed Polar View initiative is providing the herders with satellite-based snow maps. "Snow is of paramount importance for reindeer herding because its quality determines whether reindeer are able to access the pastures that lie beneath it for much of the year," said Anders Oskal, the Director of the...

The Antarctic Peninsula juts into the Southern Ocean, reaching farther north than any other part of the continent. The southernmost reach of global warming was believed to be limited to this narrow strip of land, while the rest of the continent was presumed to be cooling or stable. Not so, according to a new analysis involving NASA data. In fact, the study has confirmed a trend suspected by some climate scientists. "Everyone knows it has been warming on the Antarctic Peninsula, where there...

Glacier and Ice-Sheet Melting, Sea-Ice Retreat and Coastal Erosion Expected as a ResultTemperature change in the Arctic is happening at a greater rate than other places in the Northern Hemisphere, and this is expected to continue in the future.As a result, glacier and ice-sheet melting, sea-ice retreat, coastal erosion and sea level rise can be expected to continue.A new comprehensive scientific synthesis of past Arctic climates demonstrates for the first time the pervasive nature of Arctic...

Computer analyses of global climate have consistently overstated warming in Antarctica, concludes new research by scientists at the National Center for Atmospheric Research (NCAR) and Ohio State University. The study can help scientists improve computer models and determine if Earth's southernmost continent will warm significantly this century, a major research question because of Antarctica's potential impact on global sea-level rise."We can now compare computer simulations with observations...

The shrinking expanse of Arctic sea ice is increasingly vulnerable to summer sunshine, new research concludes. The study, by scientists at the National Center for Atmospheric Research (NCAR) and Colorado State University (CSU), finds that unusually sunny weather contributed to last summer's record loss of Arctic ice, while similar weather conditions in past summers do not appear to have had comparable impacts.The study, which draws on observations from instruments on a new group of NASA...

Arctic ice has reformed rapidly this winter after a record summer low, but it still covers less of the Arctic Ocean than it did in previous decades, NASA scientists announced today in an update of the states of Arctic and Antarctic sea ice. March is the month where Arctic sea ice traditionally hits its highest extent after the Northern Hemisphere winter and Antarctic sea ice reaches its lowest extent. NASA satellites have monitored sea ice coverage over both poles for nearly 40...

WASHINGTON -- There's more to the recent dramatic and alarming thawing of the Arctic region than can be explained by man-made global warming alone, a new study found. Nature is pushing the Arctic to the edge, too. There's a natural cause that may account for much of the Arctic warming, which has melted sea ice, ice sheets and glaciers, according to a study published Thursday in the journal Nature. New research points a finger at a natural and cyclical increase in the amount of energy in the...


Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
