Clouds blamed for record ice melt in Greenland

The 2012 summer witnessed the largest ice loss ever in Greenland since scientists started recording melt rates there in 1979, and new research indicates that clouds might be the cause.

What caused the sudden massive ice melt in Greenland? (+video)

The rapid melting of 97 percent of the surface of Greenland's ice sheet in just four days has left scientists puzzled.

Sudden Greenland ice sheet melt baffles scientists (+video)

Satellite images have shown melting over 97 percent of the surface of Greenland's ice sheet in just four days, an event thought to occur every 150 years on average.

As predicted, humongous iceberg breaks away from Greenland glacier (+video)

Last autumn, scientists predicted that the Petermann Glacier, which is larger than the island of Manhattan, would soon break way from the Greenland ice sheet. They were right.

World's oldest meteor impact crater discovered in Greenland

Scientists say they found the oldest meteor impact crater yet discovered, caused by a rock that, if it hit Earth today, would wipe out all higher life. 

Greenland's glaciers melting faster, say scientists

Greenland's glaciers are melting 30 faster than they were a decade ago, satellite images reveal. 

Greenland's ice sheet: Climate change outlook gets a little more dire

If temperatures reach 1.6 degrees C above preindustrial levels, the iconic ice sheet will probably tip toward irreversible loss. With climate change, temperatures have already risen 0.8 degrees C.

Global warming: winners and losers in the Arctic's 'new normal'

The Arctic Report Card study suggests that changes at the top of the world have led to unusual weather patterns, a greener Greenland, and lots of plankton. At least the whales are pleased.

Huge chunk of ice breaks off of glacier in Greenland

A 2.7 square mile section of Greenland's Jakobshavn Isbrae glacier has fallen into the sea, reports NASA.

The comparative costs of climate change

How much will mitigating global warming or climate chage cost the world? Here are some comparisons.

Greenland's Helheim glacier: a melting mystery

Scientists say the Greenland ice sheet is losing about 7 billion cubic feet of ice a year. Now, they are just finally beginning to uncover some reasons why its been shrinking.

Could technology repair Earth’s climate?

EarthTalk: Scientists study ways to pull greenhouse gases out of our atmosphere, but the idea is controversial.
