For Hudson Bay Polar Bears, The End is Already in Sight

The polar bear has long been a symbol of the damage wrought by global warming, but now biologist Andrew Derocher and his colleagues have calculated how long one southerly population can hold out. Their answer? No more than a few decades, as the bears’ decline closely tracks that of the Arctic’s disappearing sea ice.

High Above the Earth, Satellites Track Melting Ice

The surest sign of a warming Earth is the steady melting of its ice zones, from disappearing sea ice in the Arctic to shrinking glaciers worldwide. Now, scientists are using increasingly sophisticated satellite technology to measure the extent, thickness, and height of ice, assembling an essential picture of a planet in transition

Antarctic Sea Ice Paradoxically Growing

While Arctic sea ice continues to shrink as the world warms, the ice around Antarctica is actually growing, thanks to the influence of the ozone hole over the southernmost continent, scientists have reported.

First Hole in North Pole Ice Drilled by Explorers

A group of Arctic explorers has made the grueling journey to the North Pole and drilled a hole in the ice to take the first ever sample of ocean water at the pole in an effort to better understand the impacts of climate change. The explorers, part of a group called the Catlin Arctic Survey, completed the sampling expedition after failing to last year, reported the Guardian. The team reached the geographic North Pole on May 12 after a 60-day trek across the frigid Arctic ice.

Warmer Arctic needs new rules to limit environmental damage

A new, warmer Arctic cannot continue to operate under rules that assume it is ice-covered and essentially closed to fishing, resource exploration and development and shipping, WWF said as it launched a group of reports on protecting a newly accessible, highly vulnerable environment with profound significance for global climate, the global economy and global security. The International Governance and Regulation of the Marine Arctic reports were launched as Russian president Medvedev visits Norwegian capital Oslo for talks which include arctic issues and just before the Arctic Council meets in Greenland.

World Wide Green House Gas Air Quality

Once upon a time a trip around the world made major headlines. Nowadays it is common place and a convenient way to measure air quality around the world by plane. A plane outfitted to measure greenhouse gases has taken off from Colorado on the first leg of a 24 day mission that will take it back and forth across the Pacific Ocean from the Arctic to the Antarctic

High Arctic species plummeting across the board, others Arctic residents on the rise

Between 1970 and 2004 species populations in the high Arctic have declined by 26 percent, according to the first report by the Arctic Species Trend Index (ASTI). While this may be a natural cycle, scientists are concerned that environmental impacts such as climate change are worsening natural population fluctuations in the high Arctic

CO2 at new highs despite economic slowdown

Levels of the main greenhouse gas in the atmosphere have risen to new highs in 2010 despite an economic slowdown in many nations that braked industrial output, data showed on Monday. Carbon dioxide, measured at Norway’s Zeppelin station on the Arctic Svalbard archipelago, rose to a median 393.71 parts per million of the atmosphere in the first two weeks of March from 393.17 in the same period of 2009, extending years of gains
