Antarctica's Wilkins Ice Shelf eroding at an unforeseen pace

Via csmonitor.com

A crumbling ice shelf along the West Antarctic Peninsula has become the latest polar poster child for global warming.

This week, researchers in the United States, Britain, and Taiwan released images of long stretches of ice shearing away from the shelf. What started with the loss of a relatively thin, 26-mile-long iceberg at the end of February cascaded into the loss of 160 square miles of ice by the end of last week.

The world's rubbish dump: a garbage tip that stretches from Hawaii to Japan

Independent.co.uk: "A 'plastic soup' of waste floating in the Pacific Ocean is growing at an alarming rate and now covers an area twice the size of the continental United States, scientists have said.

The vast expanse of debris – in effect the world's largest rubbish dump – is held in place by swirling underwater currents. This drifting 'soup' stretches from about 500 nautical miles off the Californian coast, across the northern Pacific, past Hawaii and almost as far as Japan.

Charles Moore, an American oceanographer who discovered the 'Great Pacific Garbage Patch' or 'trash vortex', believes that about 100 million tons of flotsam are circulating in the region."

Escalating ice loss in Antarctica

msnbc.com: "WASHINGTON - Climatic changes appear to be destabilizing vast ice sheets of western Antarctica that had previously seemed relatively protected from global warming, researchers reported yesterday, raising the prospect of faster sea-level rise than current estimates.

While the overall loss is a tiny fraction of the miles-deep ice that covers much of Antarctica, scientists said the new finding is important because the continent holds about 90 percent of Earth's ice, and until now, large-scale ice loss there had been limited to the peninsula that juts out toward the tip of South America. In addition, researchers found that the rate of ice loss in the affected areas has accelerated over the past 10 years -- as it has on most glaciers and ice sheets around the world."

Plastic trash vortex menaces Pacific sealife-study

Reuters.co.uk: "WASHINGTON, Nov 5 (Reuters) - Old toothbrushes, beach toys and used condoms are part of a vast vortex of plastic trash in the middle of the Pacific Ocean, threatening sea creatures that get tangled in it, eat it or ride on it, a new report says.

Because plastic doesn't break down the way organic material does, ocean currents and tides have carried it thousands of miles (kms) to an area between Hawaii and the U.S. West Coast, according to the study by the international environmental group Greenpeace.

This swirling vortex, which can grow to be about the size of Texas, is not far from the Northwestern Hawaiian Islands, designated as a protected U.S. national monument in June by President George W. Bush.

The Greenpeace report, "Plastic Debris in the World's Oceans" said at least 267 species -- including seabirds, turtles, seals, sea lions, whales and fish -- are known to have suffered from entanglement or ingestion of marine debris."

No warming since 1998? Get real, deniers!

Climate Progress: "Let’s look at the data, from NASA, presented last month:

Through the first 11 months, 2007 is the second warmest year in the period of instrumental data, behind the record warmth of 2005, in the Goddard Institute for Space Studies (GISS) analysis. The unusual warmth in 2007 is noteworthy because it occurs at a time when solar irradiance is at a minimum and the equatorial Pacific Ocean has entered the cool phase of its natural El Ni�o — La Ni�a cycle.
