Study reports more global warming evidence

BOULDER, Colo., March 26 (UPI) -- U.S. researchers have used satellite imagery to determine a large part of the Antarctic ice shelf is disintegrating as result of climate change.

Scientists at the University of Colorado-Boulder's National Snow and Ice Data Center said satellite pictures show a 160-square-mile portion of Antarctica's massive Wilkins Ice Shelf has begun to collapse because of rapid climate change in a fast-warming region of the continent.

While the area of collapse involves 160 square miles, a large part of the 5,000-square-mile ice shelf is now supported only by a narrow strip of ice between two islands, said Ted Scambos, lead scientist at the NSIDC. "If there is a little bit more retreat, this last 'ice buttress' could collapse and we'd likely lose about half the total ice shelf area in the next few years."

During the past 50 years, the western Antarctic Peninsula has experienced the biggest temperature increase on Earth, rising by 0.9 degrees Fahrenheit per decade, the researchers said.

The satellite images indicate the Wilkins Ice Shelf began its collapse Feb. 28.

You live a pathetic lie re. GW.

New evidence from ice buried deep in Antarctica shows that today’s greenhouse gas levels are higher than anything the Earth has seen in 650,000 years. A team of scientists collected ice cores from a depth of two miles in a remote area of Antarctica, allowing them a glimpse far back in time.

They found that levels of carbon dioxide, methane, and nitrous oxide – three gases that trap heat in our atmosphere – have been rising, since the industrial age began, to levels unmatched anywhere in the ice record that now goes back 650,000 years.

James White, a geologist and climate change expert at the University of Colorado, told the New York Times that the findings, published in the journal Science, mean we are likely in for significant global warming. “CO2 and climate are like two people handcuffed to each other,” he said. “Where one goes, the other must follow … Our current CO2 levels appear to be far out of balance with climate when viewed through these results, reinforcing the idea that we have significant modern warming to go.”
