A massive cavity so large you could fit New York City inside of it has opened up under Thwaites glacier in Antarctica. Scientists say if it collapses, as it's likely to do within the next 50 to 100 years, it could cause a catastrophic rise in sea levels capable of flood coastal cities around the world.
The researchers behind the discovery describe what it means in a paper published Jan. 30 in the journal Science Advances. They expected to find that much ice had been lost, but were shocked by the size of the growing void.
From Denise Chow at NBC News:
Scientists have discovered an enormous void under an Antarctic glacier, sparking concern that the ice sheet is melting faster than anyone had realized — and spotlighting the dire threat posed by rising seas to coastal cities around the world, including New York City and Miami.
The cavity under Thwaites Glacier in West Antarctica is about six miles long and 1,000 feet deep — representing the loss of 14 billion tons of ice.
It was discovered after an analysis of data collected by Italian and German satellites, as well as NASA’s Operation IceBridge, a program in which aircraft equipped with ice-penetrating radar fly over polar regions to study the terrain.

TIL: Sharks are attracted to the sound of death metal. Apparently, the “dense tones” of it mimics the “low frequencies of struggling fish.” (Damn.) In 2015, a Discovery Channel crew — hoping to attract a large great white named “Joan of Shark” — dropped a speaker underwater and played some. Independent: Desperate to feature the […]
The mystery of the glorious fireball emitted by microwaved grapes (featured in my novel Little Brother) has been resolved, thanks to a paper in the Proceedings of the National Academy of Sciences in which Trent University researchers Hamza Khattak and Aaron Slepkov explain how they destroyed a dozen microwaves before figuring out that the grapes […]
The rise in a belief that the Earth is flat is bizarre and somewhat frightening, a repudiation of one of the most basic elements of scientific consensus. Texas Tech University psych researcher Asheley R. Landrum attended a 2017 flat earth convention and interviewed 30 attendees to trace the origins of their belief in a flat […]
What do Facebook, Twitter, YouTube and Google all have in common? Somewhere in their framework, they all use MySQL, that most versatile (and free!) of database management systems. And they’re not alone. If your company or the one you’d like to work for wrangles data (and who doesn’t?), they’re going to need someone with a […]
There’s a reason you’re hearing about the gig economy in every other business story these days. More than ever, people are finding income from more than one source. And if you find the right one, a side hustle can do more than just pad your pockets – it can allow you to finally get paid […]
High-def cameras are available to anyone and for much less than they were just a decade ago. Even the phones in our pockets can be used to shoot and edit short films. It’s never been easier to be a filmmaker, providing you have the technique. Enter the Film & Cinematography Mastery Bundle, an online boot […]
