Greenland ice cap melting faster than thought: study Washington (AFP) Nov 13, 2009 
Greenland's ice sheet has melted faster than previously thought, according to the results of a two-year study published by the US journal Science. Scientists reported that warmer than usual summers accelerated ice loss to 273 cubic kilometers (65 cubic miles) of a year between 2006 and 2008, amounting to a 0.75 millimeter (0.02 inch) rise in global sea levels per year. "It is clear from ... read moreWarming brings early demise to Bolivian glacier 
Chacaltaya, Bolivia (AFP) Nov 13, 2009Once home to the highest ski resort in the world and now reduced to a rocky mountainside, Bolivia's Chacaltaya range bears powerful witness to the precipitous melting of glaciers. The rusting remains of a ski lift now dominate what was once the highest ski-run in the world perched on the Chacaltaya glacier at some 5,300 meters (17,390 feet) high. Only a snowy ice cap of some 50 square ... more

Scientist: 'Big Freeze' began in Canada
Saskatoon, Saskatchewan (UPI) Nov 15, 2009 A University of Saskatchewan scientist said a severe bout of global cooling deemed the "Big Freeze" began in Canada nearly 12,800 years ago. Geologist Bill Patterson said the collapse of a large ice wall at Lake Agassiz in Central Canada nearly 12,800 years ago seriously disrupted the Atlantic Ocean's circulation patterns, prompting a major cooling period for much of Europe, the ... more Arctic scientists deflated by climate change sceptics 
Tromso, Norway (AFP) Nov 11, 2009As the world climate summit closes in, scientists monitoring the impact of global warming in the far north have grown frustrated by public apathy and disbelief about the extent of the problem. "Measuring ice thickness is extremely difficult," says Edmond Hansen, an arctic change researcher at the Norwegian Polar Institute meticulously charting the effects of climate change, ahead of the ... more Antarctica's ice loss helps offset global warming: study 
Paris (AFP) Nov 10, 2009Global warming has been blamed for the alarming loss of ice shelves in Antarctica, but a new study says newly-exposed areas of sea are now soaking up some of the carbon gas that causes the problem. Scientists led by Lloyd Peck of the British Antarctic Survey (BAS) said that atmospheric and ocean carbon is being gobbled up by microscopic marine plants called phytoplankton, which float near ... more Changing river course alters Uganda-DR Congo border 
Kampala (AFP) Nov 10, 2009The changing course of a river marking the natural border between Uganda and the Democratic Republic of Congo has caused boundary confusion in an oil rich area, a Ugandan official told AFP Tuesday. River Semliki has changed course several times since 1960 as rising water volumes sparked by melting mountain snow caps cause meandering and alteration of the boundary. "We never had an ... more |

Canada, US state give name to new sea
Vancouver, Canada (AFP) Oct 31, 2009The Salish Sea may never appear on official navigation maps, but residents of western regions in the United States and Canada hope a new name will protect their shared coastal waters. A Washington State agency approved the new name Friday for the body of water off North America's west coast that includes Puget Sound, the Strait of Juan de Fuca, and Georgia Strait. The name is partly in ... more Volcanoes Set The Stage For An Ice Age 
Columbus OH (SPX) Oct 29, 2009Researchers here have discovered the pivotal role that volcanoes played in a deadly ice age 450 million years ago. Perhaps ironically, these volcanoes first caused global warming - by releasing massive amounts of carbon dioxide into the atmosphere. When they stopped erupting, Earth's climate was thrown off balance, and the ice age began. The discovery underscores the importance of carbon ... more US to give threatened polar bears vast 'critical habitat' 
Washington (AFP) Oct 22, 2009The United States on Thursday announced plans to designate more than 200,000 square miles in Alaska as critical habitat for polar bears, a key step towards increasing protection for the threatened species. "Proposing critical habitat for this iconic species is one step in the right direction to help this species stave off extinction, recognizing that the greatest threat to the polar bear is ... more NASA Ice Campaign Takes Flight In Antarctica 
Washington DC (SPX) Oct 26, 2009Early in the 20th century, a succession of adventurers and scientists pioneered the exploration of Antarctica. A century later, they're still at it, albeit with a different set of tools. This fall, a team of modern explorers will fly over Earth's southern ice-covered regions to study changes to its sea ice, ice sheets, and glaciers as part of NASA's Operation Ice Bridge. Starting next ... more |
