An ice bridge linking a shelf of ice the size of Jamaica to two islands in Antarctica has snapped.
Scientists say the collapse could mean the Wilkins Ice Shelf is on the brink of breaking away, and provides further evidence of rapid change in the region.
Sited on the western side of the Antarctic Peninsula, the Wilkins shelf has been retreating since the 1990s.
Researchers regarded the ice bridge as an important barrier, holding the remnant shelf structure in place.
since the 1990s! you conservatives can BLAME CLINTON!....all-aboard!
Global climate change dissers, please just keep watching the local weather and american idol.

I just read an article in the Globe about how many nations are agreeing to limit tourism to Antarctica. Believe it or not tourism to that desolate place is way up over the past 20 years or so. Ostensibly the limitations are to protect the pristine ecosystem. I have a feeling its more about the fact that nobody expects it to be there much longer.
Do you know anyone who doesn't think the climate changes? I think anyone who is not brain dead is aware that the climate is always changing.
Oh...I know plenty of people. I get e-mails from them and calls when it snows in Maine the calls tend to starts with "Al Gore was wrong.....etc"
I, for one, believe in human assisted acceleration in this specific warming period. I am also fully aware that the Earth's precession cycle is a large factor in climate change. The Polar caps were not always the poles in the long history of ouor planet, but at this specific time, they serve as our 2nd greatest deflector of the sun's energy (The magnetic field being #1). When the ice turns to water....its bad.
Of course the climate is changing, it always does. The myth is global warming(conveniently changed to "climate change" in the last few years) caused by man:
Analytical Chemist Michael J. Myers, who specializes in spectroscopy and
atmospheric sensing, declared his skepticism in 2008. “I am troubled by the lack of
common sense regarding carbon dioxide emissions. Our greatest greenhouse gas is water.
Atmospheric spectroscopy reveals why water has a 95 percent and CO2 a 3.6 percent
contribution to the ‘greenhouse effect.’ Carbon dioxide emissions worldwide each year
total 3.2 billion tons. That equals about 0.0168 percent of the atmosphere's CO2
concentration of about 19 trillion tons. This results in a 0.00064 percent increase in the
absorption of the sun's radiation. This is an insignificantly small number. The yearly
increase is many orders of magnitude smaller than the standard deviation errors for CO2
concentration measurement,” Myers wrote in a September 25, 2008, essay titled “Numbers
Don’t Add Up for Global Warming.” “‘Scientific’ computer simulations predict global
warming based on increased greenhouse gas emissions over time. However, without
water's contribution taken into account they omit the largest greenhouse gas from their
equations. How can such egregious calculation errors be so blatantly ignored? This is why
man-made global warming is ‘junk’ science,” Myers added.
Climatologist Dr. Richard Keen, who is a lecturer in the Department of Atmospheric
and Oceanic Sciences at the University of Colorado, a member of the American
Meteorological Society, and has worked with the National Center for Atmospheric
Research, dissented in 2008. Keen specializes in volcanic aerosols and climate change
studies and wrote the book Skywatch: The Western Weather Guide. Keen’s 2008 global
warming PowerPoint asking “Inconvenient Questions” was featured on October 14, 2008,
on former Colorado State climatologist Dr. Roger Pielke’s Sr. website. According
to Keen, global warming ranges between a “minor inconvenience that’s overblown” or
“nothing – it doesn’t exist” or “a good thing.” “Earth has cooled since 1998,” Keen noted,
“in defiance of the predictions by the UN-IPCC.” According to Keen, “The global
temperature for 2007 was the coldest in a decade and the coldest of the millennium.” After
noting the recent cooling temps, Keen wrote “which is why ‘global warming’ is now called
‘climate change.’” Keen also pointed out that the most Antarctic sea ice on record was
recorded in 2007 and then he rhetorically asked: “Did you see [that fact] reported in the
news?” “U.S. carbon emission growth rate has slowed to 0.2 % per year since 2000,” Keen
wrote. Keen concludes his PowerPoint by stating: “Enjoy the warm climate while it lasts,
and please make enough CO2 to feed a tree.”
