Drifting icebergs are "eco-hotspots" enabling surrounding waters to absorb more CO2, a study finds.

A decade of satellite surveys of the oceans has revealed that warmer years cause a decline in phytoplankton, the vast clouds of tiny drifting plants that are a fundamental component of marine life.

Four large lakes found at the start of a rapidly moving ice stream offer the first direct link between the under-ice bodies of water and the rate at which ice flows into the ocean.

BOSTON -- The Gakkel Ridge, encased under the frozen Arctic Ocean, is steep and rocky, and scientists suspect its remote location hosts an array of undiscovered life.

Science & environment: Fishing, climate change and pollution have left an indelible mark on virtually all of the world's oceans

The tiny marine plants that make up the foundation of the food chain are directly affected by warming oceans, a recent study found.

A key food source for Antarctic seals, whales and penguins has declined about 80 percent since the 1970s in ocean waters near the Antarctic Peninsula, researchers report.

â¢ Glaciers in the Antarctic and Greenland are melting much faster than expected, and the world&#39;s fastest-receding glacier, the Grand Pacific in Glacier Bay, Alaska, has doubled its rate.

ANCHORAGE, Alaska Â Frustrated by a lack of regulations limiting global warming, a conservation group wants ribbon seals listed as threatened or endangered because their habitat Â sea ice Â is disappearing amid climate change.

Global warming (news - web sites) is heating the Arctic almost twice as fast as the rest of the planet in a thaw that threatens the livelihoods

Glaciers once held up by a floating ice shelf off Antarctica are now sliding off into the sea -- and they are going fast, scientists said on Tuesday.

Rising temperatures in the Arctic will likely increase the region&#39;s biodiversity as new species are drawn to the extreme north, but in a dramatic paradox many animals unique to the region, such as polar bears, risk extinction.

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.

Some of Antarctica&#39;s glaciers are melting faster than snow can replace them, enough to raise sea levels measurably, scientists have reported.

Icebergs that break off Antarctica and drift away turn out to be hotspots of life in the cold southern ocean, researchers report. Climate warming has led to an increase in the number of icebergs breaking away from the Antarctic in recent years, and a team of researchers set out to study the impact the giant ice chunks were having on the environment.

Description: A study released Monday that says that global warming is particularly intense in the Arctic. The melting of glaciers, thinning sea ice and changes in permafrost have acute impacts on Arctic residents
