If global warming continues unabated, melting ice could trigger a positive feedback loop that would cause sea ice to decline steadily for decades and then abruptly disappear.

Global warming is melting the Arctic ice faster than expected, and the world's oceans could rise by about a meter (3 feet) by 2100, swamping homes from Bangladesh to Florida, the head of a study said on Tuesday.

Are we really heading for an ice-free Arctic? More than 50,000 researchers hope to find an answer during a massive study of how global warming and other phenomena are changing the coldest parts of the Earth &#151; and what that means for the rest of it.

WASHINGTON - Scientists say changes in the earth&#39;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.

Early in 2002, this website published an  excellent article  which documented the activity among the various ice shelves on the perimeter of the Antarctic.  At that time, there had recently been several significant calving events, rendering vast, floating islands of ice.  Also discussed was the complete collapse, in 1999, of an ice shelf known as   Larsen B,  which was formerly the largest ice shelf on the Antarctic peninsula - the northernmost and warmest part of the continent.  The disintegration of the Larsen B shelf was called a "profound event", because it was thought to be stable.  Fortunately, when massive icebergs are calved from ice-shelves, and even when they collapse and disintegrate completely, there is no resulting rise in sea level.   It turns out though, that these same ice shelves serve a surprisingly important role in "holding back" the glaciers and land-locked ice on Antarctica which, if released into the ocean, would raise the world's sea level an estimated 20 feet (7m).      Now it's    much clearer just how important that role is.
