Antarctica Is Still There, And Growing
March 27, 2008
A comprehensive smackdown of the latest alarmism over an Antarctic
ice-sheet. Print and pin onto the desk of anyone hyperventilating.
Included is this news of increased icing:
The ice extent is already approaching the second highest level for
extent since the measurements began by satellite in 1979 and just a few
days into the Southern Hemisphere winter and 6 months ahead of the peak.

So much for that story:

An image of the Wilkins Ice Shelf disintegration taken from the British
Antarctic Survey's Twin Otter aircraft reconnaissance flight.
Satellite images reveal that a large chunk of the Wilkins ice shelf fell
into the ocean sometime around the end of February, suggesting that
climate change could be causing it to disintegrate faster than scientists
had predicted.
The 160-square-mile piece, about seven times the size of Manhattan, had
been attached to Antarctica for hundreds, or maybe even 1,500 years.
Scientists fear that the entire Wilkins shelf, more than 6,000 square
miles, could be next.
British Antarctic Survey researcher David Vaughan blamed global warming
for the smaller piece's disintegration.
Satellite images of the initial breakaway on Feb. 28 were noticed within
hours, and scientists diverted satellite cameras and even flew an
airplane over the ongoing collapse for rare pictures and video.
"It's an event we don't get to see very often," said Ted Scambos, lead
scientist at the National Snow and Ice Data Center in Boulder, Colo. "The
cracks fill with water and slice off and topple... That gets to be a
runaway situation."

Global Warming May Weaken Transport Infrastructure While icebergs
naturally break away from the mainland, collapses like this are unusual
but are happening more frequently in recent decades, Vaughan said. The
collapse is similar to what happens to hardened glass when it is smashed
with a hammer, he said.
The rest of the Wilkins ice shelf is holding on by a narrow beam of thin
ice. Scientists worry that it too may collapse.
Larger, more dramatic ice collapses occurred in 2002 and 1995.
Vaughan had predicted the Wilkins shelf would collapse about 15 years
from now. The part that recently gave way makes up about 4 percent of the
overall shelf, but it's an important part that can trigger further
collapse.
There's still a chance the rest of the ice shelf will survive until next
year because this is the end of the Antarctic summer and colder weather
is setting in, Vaughan said.
Scientists said they are not concerned about a rise in sea level from the
latest event, but say it's a sign of worsening global warming.
Such occurrences are "more indicative of a tipping point or trigger in
the climate system," said Sarah Das, a scientist at the Woods Hole
Oceanographic Institute.
"These are things that are not re-forming," Das said. "So once they're
gone, they're gone."
Climate in Antarctica is complicated and more isolated from the rest of
the world.
Much of the continent is not warming and some parts are even cooling,
Vaughan said.
However, the western peninsula, which includes the Wilkins ice shelf,
juts out into the ocean and is warming. This is the part of the continent
where scientists are most concern about ice-melt triggering sea level
rise.

So its the end of summer in Antarctica, and its now 33 deg F down
there and the ice is melting. Doesnt ice melt every spring every year
everywhere in the world?

No. If the air temperature remains below zero it does not melt.
For instance the research station at Vostok on the Eastern
Arctic plateau has never had a registered temperature warmer
than -19°C.
Antarctic is generally below freezing even in the summer
but the along the sea edge it can get water. Most of the
sea ice is gone in the warm period. The ice shelves are
different, they are created by movement of land ice
towards the sea. The shelf ice is over water in
in recent years has become thinner, which makes it more
fragile to breaking up. The mechanism of the thinning
of the shelf ice is another issue, some researchers
attribute it to "glabal warming".
The reasons which the break up is considered serious is
that the removal of the shelf ice will cause more of the
land ice to slide towards the sea and increase the rate
of ice loss on, particularly West Antarctica. Both
Greenland and Western Antarctica considered vulnerable.
Most researchers consider this a long time danger, hundreds
to thousands of years. There are those who think the
process is non-linear and can speed up to the point
that a large amount of ice mass loss can occur in 100
years.

weasel words:
"images reveal"
"suggesting:
"faster than scietists ***had*** predicted"
Gotta love that last one. Comparing what might be "suggested" by
images against what was "predicted".

Which is it? Hundreds or 1500 years? And what is the relevance
exactly? Weaselly fearmongering words.

Scientists fear? Poor guys are all aflutter. They should take some
prozac.
Quite the prediction. The entire 6,000 sq mile shelf could go. I'll
put that prediction in my list of things to watch for. Crappock, wanna
make a bet that the shelf is gonna go? A hundred bucks that it doesn't
happen in the next year.

Well of course, it has to be global warming. It could not be seasonal
cycles.

Must be real, they actually diverted satellite cameras AND flew an
airplane. Cricky, science is wonderful.

Ice shelves are created by ice migration from the land, glacier fed.
It is a steady state event, normally, if the ice shelf does not
increase in size, the feed in rate is equal to the calving rate
of ice breaking off from the shelf at the front. So you can not
get the age of a ice shelf taking samples of the ice like
in the case of coring. The ice itself could be 10ths of thousands
of years old. So, indeed the lifetime could be hundreds or a
few thousand years.
Breaking up is another even, that is acceptional.

No, not seasonal, break ups don't occur seasonally.

On your part.

You don't get to see the earth and sun line up with the center of the
galaxy very often either, so will the planet be destroyed on Dec 21 2012?

You mean like pretending one-year ice replaces a slab hundreds of feet

NASA finds evidence of widespread Antarctic melting
Last Updated: Wednesday, May 16, 2007 | 10:04 AM ET
Rising temperatures two years ago led to widespread melting of snow cover in
west Antarctica, according to scientists examining the impact of global
warming on the icy continent.
The melting of snow cover in regions in January 2005 was the most
significant Antarctic melting seen since satellites began observing the
continent three decades ago, NASA said Tuesday.
NASA's QuikScat satellite detected extensive areas of snowmelt, shown in
yellow and red, in west Antarctica in January 2005.
(NASA/JPL) It was also the first major melting detected using NASA's
QuikScat satellite, which can measure both accumulated snowfall and
temperatures in various regions.
The team of scientists found evidence of melting in regions not normally
affected: up to 900 kilometres inland from the open ocean, farther than 85
degrees south (within 500 kilometres of the South Pole) and higher than
2,000 metres above sea level.
QuikScat found maximum air temperatures at the time of melting were
unusually high, reaching more than 5 C in one of the areas. These maximum
temperatures remained above the melting point for approximately a week.
The researchers were led by Son Nghiem of NASA's Jet Propulsion Laboratory
and Konrad Steffen, the director of the Co-operative Institute for Research
in Environmental Sciences at the University of Colorado. They published
their results in a book, Dynamic Planet.
"Antarctica has shown little to no warming in the recent past, with the
exception of the Antarctic Peninsula, but now large regions are showing the
first signs of the impacts of warming as interpreted by this satellite
analysis," said Steffen in a statement.
"Increases in snowmelt, such as this in 2005, definitely could have an
impact on larger-scale melting of Antarctica's ice sheets if they were
severe or sustained over time."
The 2005 melt was extensive enough to create a layer of ice when the water
refroze, but was not long enough for the water to flow to the sea. Steffen
said if enough water from melted snow is created, it could slip through the
cracks of the continent's ice sheets and potentially affect their movement.
The Antarctic ice mass is the Earth's largest freshwater reserve, and
changes in its condition can have an impact on sea levels, ocean salinity
and water currents.
"We need to know what's coming in and going out of the ice sheets," said
Ngheim.
"QuikScat data, combined with data from NASA's IceSat and Gravity Recovery
and Climate Experiment satellites, along with aircraft and ground
measurements, all contribute to more accurate estimates of how the polar ice
sheets are changing."
