The Greenland ice sheet is vast, majestic, pristine....and peppered with bacteria that seem equipped to survive in industrial waste, according to a new study. Which really makes you question the whole the pristine bit, now, doesn’t it?
Four people are missing and nearly a dozen homes were flooded after a rare tsunami struck the west coast of Greenland on Saturday. Initial reports attributed the giant wave to a magnitude four earthquake, but speculation is emerging that the highly-localized tsunami was actually produced by a massive landslide.
Rainy weather on the east coast hasn’t stopped people from hitting the streets to march for science today. But the conditions in Antarctica and the Arctic Circle are currently quite a bit more extreme and protests in the name of facts are still rocking those two far-flung locations.
Climate change threatens to affect everything from the food we eat, to straight-up making the planet inhabitable for humanity. But our self-wrought apocalypse isn’t all bad. As the ice caps keep crumbling, they’re creating lots of icebergs we can use for badass kitesurfing stunts.
The Greenland ice sheet contains enough water to raise global sea levels 24 feet should it all melt. And a massive melt-out is exactly what seems to have happened about a million years ago, according to a groundbreaking analysis of a unique geologic sample from Greenland’s rocky underbelly.
During the Cold War, the US Army studied the feasibility of launching ballistic missiles from within Greenland’s ice sheet. When the project was done, engineers buried biological, chemical, and radioactive waste in the ice thinking it would be preserved for eternity. Shame they didn’t know about global warming.
For the first time, researchers have peered thousands of meters beneath Greenland’s glistening surface to map the bottom of the ice sheet. They were surprised to learn that it’s thawing all over the place.
Between 2011 and 2014, while humans were discovering dubstep and the wonder of selfies, Greenland was melting fast. It lost a trillion tons of ice in just three years, and the world neither noticed nor gave a damn.
A stunning structure built 150 miles inside the Arctic Circle will serve as a crucial research center for glaciologists. But perhaps more importantly, it will be a place where humans can travel to see the real-time impact of climate change.
British geophysicists have discovered evidence of an ancient drainage network buried beneath Greenland’s ice sheet that once extended across nearly a fifth of its total surface. Some of the channels within this system were about a mile deep and over seven miles wide.
Today, NASA released the image above, which shows a bunch of ice breaking up in the Beaufort sea, several weeks earlier than it should be. Also today, the European Space Agency dropped a sick GIF of a 370-square mile chunk of Antarctica cracking and heaving into the ocean.
The rapidly-melting glaciers of Greenland are moving faster than anyone thought—and this slow-motion crisis has the potential to change the world’s coastlines forever.
The New York Times posted a story today about Greenland’s melting ice, which could add another 20 feet to global sea levels. To give us the real scope, they used video shot by a drone, capturing a huge lake of meltwater that’s one of many. It’s stunning, worrying, and strangely beautiful. (Mostly really worrying.)
Ever wonder how photographers capture epic, close up images of ultra-elusive tigers? It involves reading canned food labels. Meanwhile in California, our forests are going to die off. And theres first-ever shots of a new species of whale.
The retreat of Arctic sea ice has been so dramatic over the last few years that atlases are being changed. Now it turns out Greenland’s ice sheets are also melting faster than we thought—not on the visible surface, but due to currents deep below the ocean.
By analyzing satellite photos, geologists are able to measure the depth of the lakes that form on glaciers during the summer months. Fascinatingly, the process that produces these lakes is also responsible for their remarkable depth.
As a support scientist for NASA’s Operation IceBridge mission, Jeremy Harbeck spends most of his time processing data at NASA’s Goddard Space Flight Center in Maryland. But it was on a recent visit to Greenland that he snapped this striking composite image of an iceberg frozen into North Star Bay.
Under Greenland's frozen surface is a vast network of channels, crevasses, and basins—its "glacial plumbing system." A few years ago, the water suddenly disappeared from a subglacial lake, which then collapsed into a funny silhouette that NASA likens to a "mitten," but I think looks more like a waving Yeti.
NASA scientists have used ice-penetrating radar to create a remarkable visualization of the many frozen layers that constitute Greenland's expansive ice sheet.
After staring at a barren seafloor for nearly three hours, National Geographic's Alan Turchik couldn't believe his eyes when a rare deep-sea Greenland shark suddenly drifted across the screen. (Warning: an excessively long stream of bleeped-out expletives to follow)
