Giant Antarctic iceberg snaps into the ocean after forming ominous crack

Crack. After a nearly 20-mile rift formed across Antarctica’s retreating Pine Island glacier in early September, about 115 square miles of ice — an area more than five times the size of Manhattan — has now broken off into the sea. The single largest chunk of ice is four times the size of Manhattan. This...CONTINUE READING

That strange, rectangular iceberg looks a lot less rectangular from space

Floating off the Antarctic coast, there’s a profoundly angular iceberg that has unwittingly become the object of internet intrigue.  Though scientists in Antarctica regularly spot these steep-walled “tabular” icebergs — many nearly square or rectangular — they certainly look like bizarre, unnatural forms in such a wild Earth environment. Seen from space, this particular iceberg...CONTINUE READING

That rectangular iceberg NASA found is weird as hell, and it’s not the only one

Flying 1,500 feet above the Antarctic coast, NASA scientists recently passed over a bizarrely straight-edged rectangular iceberg and snapped a picture of the floating slab.  While an intriguing image for the many of us who don’t take aerial surveys of the changing, cracking, and melting Antarctic coast, these “tabular” icebergs are a common sight for...CONTINUE READING

Vibrating slab of Antarctic ice sounds like a horror movie

In the faraway realms at the bottom of the Earth, Antarctic scientists have unexpectedly recorded bizarre drone-like sounds. After burying 34 seismic monitors in the snow atop the Ross Ice Shelf in 2014 — which is a massive Texas-sized slab of ice that floats over the Southern Ocean — the instruments picked up near-constant “buzzing”...CONTINUE READING

A 19-mile-long crack has opened up on the vulnerable Antarctic coast. What’s next?

Over a matter of days in late September, Stef Lhermitte watched via satellite as a new, massive crack formed along the edge of Antarctica’s Pine Island Glacier.  Just last year that glacier shed a Manhattan-sized slab of ice. But that particular iceberg was relatively small. Lhermitte, a geoscientist specializing in remote sensing at the Netherlands’...CONTINUE READING

If Earth’s great ice sheets start collapsing, massive undersea walls could hold them back

It would be best for humanity if the colossal ice sheets that blanket Antarctica stayed put. But, there’s growing evidence that as the planet heats up, these sprawling glaciers could begin flowing into the ocean at an accelerated pace, boosting sea levels not in feet — but yards. To halt the melting ice, some scientists...CONTINUE READING

What can hundreds of dead penguins teach us about climate change?

A warmer world might be a penguin-less world.  New research has connected hundreds of mummified penguin carcasses to two disastrous weather events thought to be influenced by climate change. The study, which was published in the Journal of Geophysical Research – Biogeosciences, warns that these events might foreshadow what’s to come if the Earth continues...CONTINUE READING

The collapse of Antarctica’s most vulnerable ice shelves would just be the start of our problems

There’s a reasonable chance that Antarctica’s two most vulnerable ice shelves — the ends of massive glaciers that float over the ocean — will succumb to Earth’s warming climate and eventually collapse into the sea.  These particular shelves, known as Larsen C and George VI, are perched on the Antarctic Peninsula — the finger that...CONTINUE READING

Antarctica is losing billions of tons of ice each year, sharply boosting sea levels

Earth-orbiting satellites are watching Antarctica thaw.  Eighty scientists from over 40 earth sciences agencies, including NASA and the European Space Agency, used satellite data from between 1992 to 2017 to find that Antarctica has lost three trillion tons of ice to the oceans over this 25-year period. Their research, published Wednesday in the journal Nature,...CONTINUE READING

Scientists are spying on frisky penguins with these kinda obvious cameras

Antarctic researchers are being a bit creepy in the name of science. They’ve been using remote timelapse cameras to keep track of the mating habits of Adélie penguins, which helps to map out their breeding cycles. SEE ALSO: How Antarctic climates mess with your camera Cameras take up to 12 pictures a day of the...CONTINUE READING
