The West Antarctic Ice Sheet covers some 760,000 square miles and is up to 1.2 miles thick. If it were to ever melt away entirely, it would add 10 feet to global sea levels. Even considering how quickly humans are heating the planet, such a change would likely unfold over centuries—that’s how much ice we’re talking about here. But scientists are finding more and more evidence that Antarctica’s ice is in far more peril than previously believed, with many abrupt changes, like the loss of sea ice, reinforcing one another.
We can now add underwater “storms” to the troubles unfolding around the frozen continent. A new paper suggests that vortices are drawing relatively warm waters across the underside of the extension of the West Antarctic Ice Sheet, known as the ice shelf, floating on the Southern Ocean, potentially accelerating its destruction.
The seemingly serene waters around the shelf are in fact rather chaotic. For one, strong winds scour the sea surface, pushing it along. But what’s driving these storms is the gain and loss of ice: when it freezes, it ejects salt, and when it melts, it injects that fresh H2O into the sea. This changes the density of ocean water, creating vortices that draw warmth from the depths. “They look exactly like a storm,” said lead author Mattia Poinelli, a glaciologist at University of California, Irvine and an affiliate at NASA Jet Propulsion Laboratory, describing the work in the journal Nature Geoscience. “They’re strongly energetic, so there is a very vertical and turbulent motion that happens near the surface.”
This is bad news for the shelf because it displaces the insulating layer of frigid water where the ice meets the sea, which should prevent melting. Other scientists have found that instead of the underbelly being flat—which would help that insulating layer accumulate—it can undulate, creating currents that similarly expose the ice to warm waters. (Researchers are only recently learning these things because it’s exceedingly difficult to see what’s going on down there—advanced robots are now getting the job done.) “We’re really trying to understand, where is warm water getting in, how’s it getting in, and what are these processes by which the ice is melting from below?” said Clare Eayrs, a climate scientist at the Korea Polar Research Institute, who wasn’t involved in the new paper.
The troubles under the shelf are bad news for the rest of the West Antarctic Ice Sheet. Think of the floating bit like a cork holding back the glacier resting on land. If melting along the shelf’s underbelly makes it break up, the sheet will march more quickly into the ocean, raising sea levels around the world.
Not helping matters is the dramatic decline of sea ice surrounding the continent. All those chunks normally act as a buffer, absorbing the wave energy that would otherwise crash into the shelf and break it apart. Sea ice also helps keep marine temperatures cool: because it’s white, it reflects the sun’s energy back into space, but with darker waters exposed, the sea instead absorbs that heat.
As sea ice disappears and the shelf degrades, more fresh water is added to the ocean, meaning more of the storms that drive more melting—and on and on. “In the future, where there is going to be more warm water, more melting, we’re going to probably see more of these effects in different areas of Antarctica,” Poinelli said.
These storms may also help explain the retreat of Antarctica’s “grounding lines,” where the ice lifts off the land and begins floating on the ocean. Researchers have previously found that as fresh water flows beneath the ice sheet and into the ocean, it creates turbulence that draws up warm water, further hastening melting. Earlier this month, a separate team of researchers used a quarter-century’s worth of data to find grounding line retreat of up to 2,300 feet a year. When that happens, warm ocean water can access more parts of the glacier, eating away at the ice and making the entire sheet system less stable.
And now storms could be adding to this attack on the grounding line. “This study provides a compelling mechanism of tiny but powerful storms that punch beneath the ice and accelerate melt,” said Pietro Milillo, a physicist at the University of Houston who co-authored the retreat paper but wasn’t involved in the storm research. “The kind of retreats that we see in our dataset can be partially explained with these underwater storms.”
Just how much more melting we might see because of these storms remains an open question. Also, the finding came out of a model, though Poinelli said scientists have observed the dynamic in another area of Antarctica. Scientists desperately need more data to get a better idea of how fast this ice will disappear and, as a consequence, how quickly sea levels will rise. “We sometimes think the ice sheet responds slowly to changes, but this work, and our work, remind us that Antarctica can change on timescales of days or weeks,” Milillo said. “We need to monitor the underside of the ice shelf with the same urgency we monitor atmospheric storms.”

![Sam Altman’s project World looks to scale its human verification empire. First stop: Tinder. | TechCrunch
At a trendy venue near the San Francisco pier, Sam Altman’s verification project World celebrated its next evolution and rapid expansion of its ambitions. And it’s starting with Tinder.
Tools for Humanity (TFH), the company behind the World project, announced Friday plans to integrate its verification tech into dating apps, event and concert ticketing systems, business organizations, email, and other arenas of public life.
“The world is getting close to very powerful AI, and this is doing a lot of wonderful things,” said Altman, speaking before a packed crowd at The Midway. “We are also heading to a world now where there’s going to be more stuff generated by AI than by humans,” he added. “I’m sure many of you [have had moments] where you’re like, ‘Am I interacting with an AI or a person, or how much of each, and how do I know?”
World (formerly Worldcoin) distinguishes itself from many of its ID verification peers by offering the ability to verify that a real, living human is using a digital service while still protecting that person’s anonymity. There is some complex cryptographic alchemy behind this (something called “zero-knowledge proof-based authentication”). The upshot: The company is creating what it calls “proof of human” tools, which are mechanisms that can verify human activity in a world rife with AI agents and bots.
Its chief tool for verification is a spherical digital reader called the Orb that scans a user’s eyes, converting their iris into a unique and anonymous cryptographic identifier (known as a verified World ID). This can then be used to access World’s services, although users can also access World’s app without one.
Altman kept his remarks brief on Friday (TFH’s co-founder and CEO, Alex Blania, was absent due to a last-minute hand surgery, Altman said). He then turned much of the presentation over to World’s chief product officer, Tiago Sada, and his team.
Sada explained that World was launching the newest version of its app (the last version was launched at an event in December), along with a plethora of new integrations for its technology.
World has been preparing, for some time, to deploy a verification service for dating apps — most notably, Tinder. Last year, Tinder launched a World ID pilot program in Japan. That pilot was apparently a success because World announced that Tinder would be launching its verification integration in global markets —including the U.S. The program integrates a World ID emblem into the profiles of users who have gone through its verification processes, thus authenticating them as a real person.

World is also courting the entertainment industry by launching a new feature called Concert Kit, where musical artists can reserve a certain number of concert tickets for World ID-verified humans. This is designed to ensure that fans are safe from scalpers who often use automated ticket-buying bots to scarf up seats. Concert Kit is compatible with major ticketing systems, including Ticketmaster and Eventbrite, and the company is promoting it via partnerships with 30 Seconds to Mars and Bruno Mars — both of whom plan to use it for their upcoming tours.
The event was full of many other announcements, including some aimed at businesses. A Zoom/World ID verification integration seeks to battle a supposed deepfake threat to business calls, and a Docusign partnership is designed to ensure signatures come from authentic users.
The company is also working on a number of features in anticipation of the Wild West of the agentic web, including one called “agent delegation,” in which a person can delegate their World ID to an agent to carry out online activities on their behalf. A partnership with authentication firm Okta has also created a system (currently in beta) that verifies that an agent is acting on behalf of a human. The system is set up so that a World ID can be tied to a specific agent and then, when the agent goes out into the web to operate on that person’s behalf, websites will know a verified person is behind the behavior, said Okta’s chief product officer, Gareth Davies, at the event.
So far, it’s been difficult for World to scale, due largely to the verification process itself. For much of the company’s history, to get its gold standard, you had to travel to one of its offices and have your eyeballs scanned by an Orb — a fairly inconvenient (not to mention weird) experience.

However, World has continually made moves to increase the ease and incentive structure for verification. In the past, it offered its crypto asset, Worldcoin, to some members who signed up and has distributed its Orbs into big retail chains so that users can verify themselves while they’re out shopping or getting a coffee. Now the company is announcing that it is significantly expanding its Orb saturation in New York, Los Angeles, and San Francisco. The company also promoted a service where interested users could have World bring an Orb to their location for remote verification.
In a conversation with TechCrunch, Sada also shared that World has attempted to solve the scaling problem by creating different tiers of verification. The highest tier is Orb verification, but below that, World has previously offered a mid-level tier, which uses an anonymized scan of an official government ID via the card’s NFC chip.
The company also introduced a low-level tier, or what Sada called “low friction”— meaning low effort, I guess, but also “low security” — which involves merely taking a selfie.
Selfie Check, which Sada’s team presented during the event, is designed to maintain user privacy.
“Selfie is private by design,” said Daniel Shorr, one of TFH’s executives, during the presentation. “That means that we maximize the local processing that’s happening on your device, on your phone, which means that your images are yours.”
Selfie verification obviously isn’t new, and fraudsters have long managed to spoof it. “Obviously, we do our best, and it’s like one of the best systems that you’ll see for this. But it has limits,” Sada told TechCrunch. Developers looking to integrate World’s services can choose from the three different verification tiers depending on the level of security that’s important to them, he noted.

![‘Project Hail Mary’ Won’t Be Coming to Streaming Any Time Soon
With all the excitement of movies to come this week thanks to CinemaCon, it was almost easy to forget that MGM provided an interesting update on one of our favorite movies of the year that’s already out: Project Hail Mary will head back to IMAX theaters this weekend for an extended theatrical run. But that extension also means one thing: you’ll have to wait to stream it at home for a good while longer. During its presentation at CinemaCon this week MGM confirmed that Phil Lord and Chris Miller’s sci-fi hit would make its return to IMAX screens for a limited-time, one-week run starting this weekend, a move that will likely inch Project Hail Mary ever closer to crossing the $600 million box office mark. But to put a finer point on the news, Miller took to Twitter yesterday to confirm specifically that the extension means you won’t be able to watch the film at home for the forseeable future.
We announced yesterday that MGM is extending the exclusive theatrical window for PROJECT HAIL MARY so it won’t be on streaming anytime soon. This is a movie that needs to be seen on a big screen – and w a full return to IMAX screens for 1 week only starting this weekend, make… https://t.co/suK8NYpgWM — Christopher Miller (@chrizmillr) April 16, 2026 “It won’t be on streaming any time soon,” Miller’s tweet reads in part. “This is a movie that needs to be seen on a big screen […] Bring friends and loved ones. It’s an experience to share with others.” Project Hail Mary launched on March 20, so it’s not too surprising that it’s not headed home just yet—it’s just shy of a month into its theatrical window, which has now been extended by at least another week with the return to IMAX. But as studios begin to try realigning towards more theatrical releases with longer exclusivity windows again (one of the lingering aftereffects of covid’s impact on movie theaters), we should probably expect some of the biggest films of the year and beyond to try and hold off of hitting streaming for as long as they can.
At least in Project Hail Mary‘s case, you can still go and see it somewhere, even if it’s not at home. Good things come to those who wait, but for now, you can head to a movie theater to get your fix again. Want more io9 news?
