Greenland

Previously, only a handful of lakes locked beneath the ice had been identified.

The arch that connects Greenland and Ellesmere Island normally breaks up in June or July.

Researchers ran hundreds of simulations for different climate scenarios to see how the ice will respond in the coming centuries.

As the Earth's climate warms, melting ice sheets are expected to lead to an increase in global sea levels.

Should a similar event take place today, it would have a devastating effect on society, scientists say.

Last November, researchers announced that the discovery of another large impact crater below Greenland's ice, just over 100 miles away.

There is some good news, however—sea level rise won't be quite as bad as expected.

"The only thing we can do is adapt and mitigate further global warming—it's too late for there to be no effect," the study's author warned.

"It is not impossible to imagine that China could pressure the Greenlandic government to ask the Americans to leave," an expert said.

"There are 180 inhabitants, and we are very concerned and afraid," one resident said.

Satellite data over 25 years confirms what climate models had predicted.

This heat source is found all over the planet and is extremely difficult to measure.

That Greenland shark found to be 512 years old is not the only impressively long-lived animal.

The melting of Greenland's ice sheet is the biggest contributor to sea level rise.

The acceleration is driven by expansion of water and melting ice sheets.

The unusual crack in the center of the ice shelf could break off and form a giant iceberg.

Scottish government will table plans this week.

Nicola Sturgeon may have to take Scottish independence off the table to get a deal with the EU.

One of the most important ocean current systems could be slowing down, according to a new study.

It'll take more than just the U.S. toeing the line.
