A comprehensive new study has tracked long-term ice loss in Greenland, and found that the Ice Sheet has lost 3.8 trillion tonnes of ice since 1992 – and the annual rate is rising faster than previously expected.

Declassified spy satellite photos have revealed that compared to the last quarter of the 20th century, Himalayan glaciers have been melting twice as fast this century. In a rare piece of good news, a separate study has shown that a Greenland glacier has gained ice for the third year in a row.

A new series of photographs from award-winning aerial photographer Tom Hegen explores the abstract beauty in icebergs. Shot off the west coast of Greenland, Hegen’s work captures the majesty of these giant white castles.

Scientists have found an ancient meteor crater under the Greenland ice cap that's larger than Paris. Discovered using ground-penetrating radar, the possibly three-million-year-old impact crater is 19 miles in diameter, about 1,000 ft deep, and is buried under 3,200 ft of glacial ice.

ScienceA few years ago, researchers studying stromatolites in Greenland dated them to 3.7 billion years old, making them the oldest evidence of life on Earth. However, a new study has now taken another look at the rocks and found that they probably weren’t biological in origin.

The Earth’s spin naturally drifts on its axis over time, and that’s generally chalked up to the way mass is distributed and redistributed across the planet’s surface. Now, NASA scientists studying data gathered across the entire 20th century have identified three broad processes that play a part.

The International Chronostratigraphic Chart has officially been revised. That means our current point in Earth’s geological timeline has been updated so that we’re now living in the Meghalayan age, which began 4,200 years ago with a two-century drought that destroyed several civilizations.

Many consequences of climate change can be imperceptible, but others can catch our eye in the most dramatic of ways. One such example is a monumental chunk of ice breaking off a glacier and washing into sea, something dramatically captured on video by scientists in eastern Greenland last week.
