Science Torpedoes Reveal How Greenland Is Melting From Below
If the climate keeps warming the way it has, Greenland may finally live up to its name (which was probably bestowed on it by some colorblind viking). The island’s glacier-crusted surface is melting, and a lot of this is from balmier atmospheric temperatures. But as the saying goes, that’s just the tip of the iceberg. The oceans are becoming more tepid as well, and that warmer water is causing the glaciers to thaw from below...

Making lemonade out of climate change - Science unveils the sheer beauty of Planet Earth
You might expect that being a science writer primarily focused on climate change and climate science could put me in a bad mood. You can see this if you read the comments on many of my blogs, on our NASA Climate Change Facebook page and on my TEDx video. Many commenters think I should express more alarm about our changing climate...

Greenland on the edge - Where ice meets water at the bottom of the sea
A person can look at a thing over and over again before finally seeing it for the first time. That’s how I felt standing in front of an Arctic map at the University of Washington in Seattle. I gazed at the northwest coastline of Greenland, north of Baffin Bay, up where the Canadian Queen Elizabeth Islands come close to Greenland...

OMG: How fast are oceans melting Greenland?
We know more about the moon and other planets than we do some places on our home planet. Remote parts of the world ocean remain uncharted, especially in the polar regions, especially under areas that are seasonally covered with ice and especially near jagged coastlines that are difficult to access by boat. Yet, as global warming forces glaciers in places like Greenland to melt into the ocean, causing increased sea level rise, understanding these remote places has become more and more important...

OMG: Is the Ocean Melting the Ice?
At 1.7 million square kilometers (660,000 square miles), the Greenland ice sheet is three times the size of Texas. On average, the ice is about 1.6 kilometers (1 mile) deep and contains enough water to raise global sea levels about 6 meters (20 feet) if it were all to melt...

Glaciers by Sight, Glaciers by Radar
The Oceans Melting Greenland (OMG) team is flying NASA’s G-III at about 40,000 feet. On a clear day, this altitude also provides a stunning perspective of one of the world’s two great ice sheets (the other is Antarctica). The flight Saturday, March 26, over the northeast coastline was one of those clear days...

In Greenland, Another Major Glacier Comes Undone
It's big. It's cold. And it's melting into the world's ocean. It's Zachariae Isstrom, the latest in a string of Greenland glaciers to undergo rapid change in our warming world. A new NASA-funded study published today in the journal Science finds that Zachariae Isstrom broke loose from a glaciologically stable position in 2012 and entered a phase of accelerated retreat. The consequences will be felt for decades to come...

You’re gonna lose it when you hear about Oceans Melting Greenland
This morning when I told someone I’d interviewed NASA oceanographer Josh Willis for this blog, they replied, “Isn’t Josh Willis a climatologist?” “Aha!” I said. “That’s a problem. Not knowing that Earth’s ocean is responsible for controlling the climate is major. Oceanographers are climatologists.”...

Why NASA's so worried that Greenland’s melting could speed up
Antarctica contains vastly more ice than Greenland. However, Greenland is subjected to the rapidly warming temperatures of the Arctic. The result is that for now at least — and as you can see above — it is losing ice mass considerably faster than Antarctica is, to the tune of several hundred gigatons a year...

NASA: Sea Level Rise is Going to get Much Worse
Eleven of the fifteen largest cities in the world are located on the coast. The tenuous barrier between land and sea was a boon for humanity in the past, providing access to ports around the globe, building lifelines of trade between countries, and raising triumphs of steel and concrete high into the air. Now, sea levels are also on the rise, putting millions of people who live in those cities in harm's way...
