The Thwaites Glacier, an enormous shelf of ice in the Antarctic, has been given the ominous nickname of the “Doomsday Glacier” — because if it were to change collapse, it could have profound implications for the future of sea level rise and the fate of coastal communities.

Scientists have watched in horror as its retreat has accelerated significantly. Now, as detailed in a study published by the International Thwaites Glacier Collaboration (ITGC) and spotted by Wired, large cracks forming in the ice shelf are continuing to weaken its structural integrity. Doomsday has never been closer.

If it were to collapse under its own weight, scientists suggest it could ultimately trigger up to 11 feet of global sea level rise, meaning certain devastation for tens of millions of people.

Now, a team of researchers from the University of Manitoba have analyzed satellite data from 2002 to 2022, and observed how cracks in the Thwaites Glacier continued to grow around a shear zone.

“Over the past two decades, the shelf has experienced progressive fracturing around a prominent shear zone upstream of its pinning point, gradually compromising its structural integrity,” the paper reads.

Over the two decades, satellite images showed the “total area length of fractures” growing from around 100 miles to over 200 miles, but the average length actually decreased, suggesting major new stresses acting on the glacier.

A similarly alarming situation is playing out below the water line as well. Another recent study observed how warming ocean waters are melting ice shelves like the Thwaites Glacier, changes that can be tracked not just over years, but mere hours and days as well as swirling eddies of water that can measure up to six miles across spin and burrow underneath these glaciers.

The international team of researchers also identified a worrying feedback loop: new cold water from the ice shelf mixes with warmer saltier ocean waters, causing ocean turbulence, which in turn, melts even more ice.

“This positive feedback loop could gain intensity in a warming climate,” coauthor and UC San Diego assistant professor Lia Siegelman told CNN.

Scientists are still racing to fully understand the devastating effects of global warming on the Doomsday Glacier. One thing’s for sure: the prognosis isn’t great. According to the ITGC’s 2025 report, the glacier’s retreat has “accelerated considerably over the past 40 years.”

“Although a full collapse is unlikely to occur in the next few decades, our findings indicate it is set to retreat further, and faster, through the 21st and 22nd centuries,” the report reads.

“Immediate and sustained climate change mitigation (decarbonisation) offers the best hope of delaying this ice loss and avoiding initiation of similar unstable retreat in marine-based sectors of East Antarctica,” the group wrote.

📌 MAROKO133 Breaking ai: China to treat drones as aircraft under new laws to impro

China will officially bring in tighter regulations on drones from July 1, 2026. From this date, drones will be treated as aircraft under Chinese aviation law, rather than loosely regulated technology, as they are now.

Under the new regulations, drones will be subject to certification, traceability, and legal liability. This both tightens control and signals long-term state backing for the drone industry as a major economic pillar.

To make this change, China plans to update its 1995 Civil Aviation Law to explicitly include civilian uncrewed aircraft (drones). That’s a big deal, as previously, drones sat in a legal grey zone, handled by patchwork regulations.

According to the South China Morning Post (SCMP), the regulations will get an entirely new chapter dedicated to drones. It will also make the legal responsibilities for drones much stronger and transparent.

With regard to certification, the new laws will require anyone involved in the drone industry to become certified. This will include designers, manufacturers, importers, maintenance companies, and operators to get certified with the Civil Aviation Administration of China (CAAC) unless exempted.

Strengthening the law, not banning drones

According to SCMP, this builds on a 2024 interim rule that medium and large drones already needed certification. Under this law, small and micro drones were mostly exempt; now those rules are permanent law, not temporary guidance.

Each drone must now also acquire its own unique ID code tied to a real-name registration. This will allow authorities to trace who owns, who flew, and where it came from.

It should also now mean that anonymous drone use becomes much harder and makes enforcement far easier after incidents. The new law will also crack down on unsafe or disruptive drone usage near places like airports.

Penalties will include fines, confiscation of equipment, and potential prison time. The new regulations also come at a time when the drone economy in China is exploding.

Drones are currently being rolled out to provide things like parcel delivery and urban logistics, but plans are also afoot to flesh out passenger drones and air taxis.

According to some estimates, the drone economy was worth as much as 500 billion yuan in 2023. This is projected to exceed 2 trillion yuan (about $280bn) by 2030.

Improving safety and accountability

However, repeated accidents have plagued China in recent years, leading to disruptions in civilian flights and forced no-fly zones. The new laws, therefore, are being brought in to improve safety and industrial policy.

They are not about killing the drone industry, but rather an attempt to standardise it, help scale it safely, and protect domestic production. It is signals China’s long-term support for the drone industry, ensuring it remains a pillar of its economy for many years to come.

Some experts have also highlighted that the new laws are likely, in part, a response to US restrictions on Chinese drones. The Federal Communications Commission (FCC) has, for example, labelled Chinese drones as a potential national security risk.

To this end, the US has restricted Chinese drone use in the United States, a move that China has called discriminatory. In response, China appears to be attempting to match US-style certification, while going further with mandatory traceability and real-name registration.

This not only gives the Chinese government more control over its industry, but can also be used as “proof” that Chinese drones are safe and their manufacturers are accountable.
