Few consequences of global warming pose as severe a threat to human society as sea-level rise. But scientists have yet to figure out how to predict it.

A faster-than-expected thaw of the Arctic is likely to open legendary short-cut routes between the Pacific and the Atlantic but experts say icebergs and high costs will prevent any trans-polar shipping boom.

Researchers plant a tracking beacon on a two-billion-tonne block of ice floating off the Canadian Arctic coast.

Ice cores drilled from under the floor of the Arctic Ocean show it was once warm enough for swimming.

Beneath the snow, ice and bitter cold of Antarctica, scientists have discovered a network of lakes that fill and empty with rapidly flowing water.

An ambitious two-year effort aims to understand the vital, shifting dynamics of ice, oceans and life at the ends of the earth.

For an imaginary point in the midst of an ice-capped sea, the North Pole is a surprisingly hot piece of real estate.

Description: New evidence is reported that rising global temperatures could have rapid effects on the Antarctic ice pack and on ocean levels.

Scientists say changes in the earth's climate from human influences are occurring particularly intensely in the Arctic region, evidenced by widespread melting of glaciers, thinning sea ice and rising permafrost temperatures.

Nifty Icebergs, released by global warming from the icy embrace of Antarctica, have surprised scientists by playing host to many forms of life.â¦

It may be freezing cold and covered in ice now but 70 million years ago the Arctic Ocean was as tepid as the Mediterranean.

A large network of waterways helps carry ice from the center of Antarctica to the ocean, scientists say, in a finding that may help clarify how global warming will affect the world's sea levels.

Scientists have found that the ice in Greenland and the Arctic is melting so rapidly that most of it could be gone by the end of the century. Low-lying lands could be flooded and polar bears could go extinct, among other possibilities.

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.
