Unquiet Ice Speaks Volumes on Global Warming
Nothing, that is, until early in the Antarctic summer of 2001–2002. In
November 2001 Scambos got a message he remembers vividly from Pedro Skvarca, a
glaciologist based at the Argentine Antarctic Institute in Buenos Aires who was
trying to conduct fieldwork on Larsen B. Water was everywhere. Deep cracks were
forming. Skvarca was finding it impossible to work, impossible to move. Then, in
late February 2002, the ponds began disappearing, draining—the water was indeed
chiseling its way through the ice shelf. By mid-March remarkable satellite
images showed that some 1,300 square miles of Larsen B, a slab bigger than the
state of Rhode Island, had fragmented. Nothing remained of it except an armada
of ice chunks, ranging from the size of Manhattan to the size of a microwave
oven. Our emergency landing site, stable for thousands of years, was gone. On
March 20 Scambos’s striking satellite images of the collapsing ice shelf
appeared above the fold on the front page of the New York Times.

Ice cores show faster global warming
Climatologists from Bern University said their study also showed that
concentrations of greenhouse gases are increasing at a faster rate,
Swissinfo.com reported. For example, the concentration of carbon dioxide
increased by 31 parts per million during one 1,600-year interval in the
pre-industrial period -- its fastest growth before the industrial age -- and
went up by the same amount in the past 20 years

Ocean CO2 levels can influence climate
To discover how the situation has changed since the last ice age, researchers
studied 20,000-year-old mud samples from the sub-Arctic Pacific Ocean lying
approximately three feet below the present sea bed. They found the water in the
ocean's depths exchanged less CO2 with the atmosphere than it does at present,
while capturing more atmospheric CO2 than the water does today, suggesting as
oceans become warmer as a result of climate change they release more carbon
dioxide into the atmosphere.

Antarctic Ice Loss Speeds Up, Nearly Matches Greenland Loss

Antarctic volcanoes identified as a possible culprit in glacier melting
Volcanic heat could still be melting ice to water and contributing to
thinning and speeding up of the Pine Island glacier, which passes nearby, but
Vaughan said he doubted that it could be affecting other glaciers in western
Antarctica, which have also thinned in recent years. Most glaciologists,
including Vaughan, say that warmer ocean water is the primary cause of thinning.

North Atlantic Warming Tied To Natural Variability
A Duke University-led analysis of available records shows that while the

Trouble in Them Thar Hills
Warmer temperatures are only part of the problem, explained geographer Thomas
Painter of the University of Utah, Salt Lake City, who presented his own
research on snowpack in the West at the meeting. Also contributing is carbon
black, known more commonly as soot, which continually rains down on the glaciers
but tends to concentrate on the surface of the ice. By the calculations of his
research team, Painter said, soot increases heat absorption from the sun's rays
by 43%. That provides "yet another reason" to limit carbon black from industrial
emissions, says climatologist Claire Parkinson of NASA's Goddard Space Flight
Center in Greenbelt, Maryland.

After the Thaw
The National Snow and Ice Data Center reports that Arctic ice shrank by
131,000 square miles between August 17 and 21, leaving ice coverage that is well
below the 2005 record low of 2.05 million square miles. This has made the
Northwest Passage easier to access than was thought possible even five years
ago. “We used to say that maybe by the middle of the century the Arctic would be
seasonably navigable,” says Sheldon Drobot, an Arctic researcher with the
Colorado Center for Astrodynamics Research. “Climate change is moving faster
than we thought in the Arctic. At the current rate, we could see a seasonal
shipping route in the next decade or two.”
