ICE Sculptures like Icebergs glide in a troubled agitated sea, ironically revealing hope or senseless fate ? Some jutting
tongues of floating ice, where riverlike glaciers protrude into the sea, are rapidly thinning. Measurements this year by Steffen
and others on the Petermann Glacier in northern Greenland show that more than 150 feet of thickness melted away under that
tongue in the last year. Such melting can speed the seaward movement of ice in the same way that removing a doorstop lets
a door swing freely. Some oceanographers say global warming may already be pushing the North Atlantic toward instability.
In less than 50 years, waters deep in the North Atlantic and Arctic have become significantly fresher, matched by growing
saltiness in the tropical Atlantic. Worldwide, seas have absorbed enormous amounts of heat from the warming atmosphere. A
big outflow of water from Greenland could take the system to a tipping point, some say.
“The models are not nearly as sensitive as the real world,” Dr. Richard B. Alley, an expert at Penn State on Greenland’s
climate history, said. “That’s the kind of thing that makes you nervous.” “It’s as if we’re
running a gigantic uncontrolled experiment on the climate system and we know we have the capability of making large impacts,”
said Robert Hawley, a glaciologist from the University of Washington stationed at the Summit Camp, a permanent dome-topped
installation at the highest point of the ice sheet. “Should we continue just to experiment or should we try to figure
this out first?”
On Greenland efforts are under way to resolve the big uncertainties. Dr. Joseph R. McConnell, a snow hydrologist from the
Desert Research Institute in Reno, Nevada, is examining whether forces other than global warming could be responsible for
changes here. Under a Nasa grant, he recently completed a three-week 250-mile snowmobile crossing of the ice sheet, extracting
four shaftlike ice cores en route.
He marveled at how much ancient water was stored in front of him.
“If Greenland melted,” he said, “it’d raise sea levels by 20 feet. There goes Florida. There goes
most of the Mississippi embayment. There go the islands in the South Pacific. Bangladesh is obliterated. Manhattan would have
to put up dikes.”

Although much work is needed to solve the puzzle, he added, the hints of big changes are building. “There’s definitely
a lot of melting going on,” McConnell said, flinching as a crack echoed from the warming white cliff and a giant ice
slab shifted ever so slightly.
These ice figures lost in sea represent humanity as they transmit harmony and peace as they face the end, blending the tragic
with the beautiful, what a platonic way to say goodby ! as we continue to suicide and destroy the earth everyday, Some predict
that in the future millions of people in low-lying countries like Bangladesh will be forced to migrate. But a movement of
people on that scale will create its own international tensions.
The world will have to learn to cope with refugees from climate change.
is that what you want? is the question the artist is posing..US President George W Bush had a 10-year programme to reduce
the carbon intensity of the US economy by 18% by 2012.
The government was totally committed to carrying out the programme and wanted to wait to see the results, he said .The US
has told a UN conference on global warming that it has no intention of re-joining international efforts to cut greenhouse
gas emission . Mr Watson admitted that even if the US achieved its target, it would still be producing 15-16% more greenhouse
gases while the rest of the industrialised world was committed to an absolute reduction. He was scathing about the way the
rest of the world was approaching climate change, arguing that the Kyoto agreement was a political document and not based
on sound science.So listen you scientists, with your degrees and PhD's we the Bush adninistration, don't need or care for
your advice, we'll just say on the news that despite the bad weather we are enjoying our selves, we will rebuild our houses
over and over because we are rich we can afford it we are American as you can see on T.V. everything is fine these scientists
are a joke !!...and who is crazy them or you ? WAKE UP
