Ozone depletion may have triggered a mass die-off of ancient fish and plants by ultraviolet ray exposure 358 million years ago.

This clip looks at the physical features, climate and culture of Denmark.

This clip looks at the physical features, climate, history and culture of Greenland.

Greenland's ice sheet has lost 4,700 gigatons of ice since 2002, enough to submerge the entire U.S. under half a meter of water, according to a Polar Portal study.

Many outlet glaciers in Greenland feed ice from the land into fjords, where discharge of icebergs and melting of the glaciers by warmer ocean waters contribute to rising sea levels. David Holland of NYU studies what happens in the fjord...

A National Science Foundation-funded team of researchers from the Universities of Wyoming and Montana has discovered that the Greenland Ice Sheet is sliding more than anyone realized. Surprisingly, they found that the ice slides across...

A huge hole has been discovered in the Arctic’s oldest and thickest ice, previously thought to be the most stable ice in the region.

A ‘massive melting event’ has affected Greenland’s ice sheet during a heat wave that has brought temperatures more than twice as hot as seasonal averages.

NASA's Oceans Melting Greenland (OMG) mission uses ships and planes to measure how ocean temperatures affect Greenland's vast icy expanses. Jakobshavn Glacier, known in Greenlandic as Sermeq Kujalle, on Greenland's...

New research suggests that the melting of the ice sheets is shifting the location of the Earth's spin axis, meaning the North and South poles are moving. "If we lose mass from the Greenland ice sheet, we are essentially putting mass...

How can the finding of paleoclimatologists help validate climate models?

Scientists used cutting-edge technologies to uncover six amazing secrets hidden under the Greenland ice sheet.<br/>

Researchers from the University of Alaska at Fairbanks (UAF) have identified tens of thousands of methane seeps in areas along the coast of Alaska and Greenland. Some experts believe the escape of large quantities of previously frozen...

Join Operation IceBridge Project Manager Christy Hansen on location near Antarctica as she discusses her career at NASA. Hansen, who began in NASA's space flight program, recently joined the Operation IceBridge team. As Project...

New NASA research found that large crevasses provide aquifer water upstream of Greenland's Helheim Glacier with a clear escape to the ocean. This discovery helps confirm that the water, which is held in a layer of...

This video highlights the potential risks of rising sea levels in Singapore due to climate change. It emphasizes the impact on various areas of the city and the urgency for action. The narrator discusses the rate of sea level rise, the...

From June 2002 to early October 2011, the Advanced Microwave Scanning Radiometer for the Earth Observing System (AMSR-E) on the Aqua satellite provided a wealth of data about the Earth's water cycle. Among the many variables...

Scientists at the University of Alaska Fairbanks’ Geophysical Institute used data from NASA’s Operation IceBridge to develop a more accurate model of how the Greenland Ice Sheet might respond to climate change in the...

Earth’s rising seas are some of most visible signs of our warming planet. Over the last 20 years, NASA satellites, airborne missions and field campaigns show a steady rise in global sea levels as the world’s polar ice sheets melt. As...

The North Atlantic Current is a vast flow of warm seawater from the Gulf of Mexico that makes northwestern Europe’s mild climate possible.<br/>

After the death of his daughter and losing his job, Felix Phillips needs to rebuild his life. But he won’t get very far unless he respects the women who come to his aid. In Hag-Seed, Margaret Atwood portrays the complex and vital role...

What if you could measure a glacier in such detail that you could visualize its surface in 3D? And what if you could compare that view with data from one, two, even 20 years ago? NASA airborne campaigns like Operation...

In a remote area of northwest Greenland, an international team of scientists has made a stunning discovery, buried beneath a kilometer of ice. It’s a meteor impact crater, 300 meters deep and bigger than Paris or the...

Limnognathia maerski is one of the smallest known animals, yet has one of the most complicated jaw structures in the animal kingdom. It is currently the only species in phylum micrognathozoa that humans know about, however, there are...
