Huge Piece of Ice Cap Splits Off, Worrying Scientists

42-square-mile chunk breaks away in northeastern Arctic

(Newser) - An enormous chunk of Greenland's ice cap has broken off in the far northeastern Arctic, a development that scientists say is evidence of rapid climate change. The glacier section that broke off is 42.3 square miles, the AP reports. It came off of the fjord called Nioghalvfjerdsfjorden, which...

Scientists Find Key Culprit in Antarctic Ice Melt

Underwater storms bringing warm water to polar ice: study

(Newser) - Storms aren't just a result of global warming, they may actually be causing the unstoppable Antarctic ice melt . Robots patrolling more than 3,250 feet below the Weddell Sea have discovered underwater storms are helping thaw Antarctic ice as they drive warm water toward polar ice shelves. Essentially, researchers...

'Frankly Nutty' Arctic Adventure Ends in Tragedy

Research offers window into changes

(Newser) - Over the next three summers in Greenland, a group of international scientists will unearth samples of the country’s ice core down to its very bedrock, in the hopes of painting a complete picture of Earth's changing climate. Each layer provides a dated mixture of water and air bubbles that...

Huge Chunk Snaps Off Largest Arctic Ice Shelf

Arctic's biggest ice shelf is falling apart and not regenerating

(Newser) - An 8-square-mile chunk of ice has broken off an ancient ice shelf in Canada's Arctic, the Globe & Mail reports. The Ward Hunt Shelf, the biggest in the Arctic, has shrunk over the last century from 3,500 square miles to less than 400 today. Huge cracks have appeared in...

Polar Meltdown Threatened This Summer

North Pole may be ice free for the first time in human history

(Newser) - The North Pole may become free of ice this summer for the first time in human history. Thick Arctic sea ice that normally covers the polar region has been replaced by ice that formed only in the last year and is susceptible to seasonal melting, reports the Independent. It's a...

Old Arctic Ice Melting Away

Formations older than 1 year see heavy declines

(Newser) - The Arctic's oldest, thickest ice is melting and may undermine the entire Arctic ice cap, NASA satellite photos show. Some 965,300 square miles of perennial ice, more than a year old, has melted over the past year—a 50% decrease. Losses of older, hardier frost are even greater: Three...

Island Paradise Battles Global Warming

Republic of Maldives sounds alarm about rising sea levels

(Newser) - The Republic of Maldives has a lot to fear from rising sea levels, but the chain of tiny islands in the Indian Ocean is doing something to protect itself. The nation has built a concrete wall around the capital, Male, and constructed an entirely new island 7 feet higher than...

Researchers put 40% of Arctic underwater by 2050

(Newser) - At least 40% of the polar icecap will be gone by 2050, Seattle scientists predicted today, putting the meltdown way ahead of earlier predictions that so much ice would take a century to vanish.
