'Wake-Up Call': Antarctic Ice Shelf the Size of Los Angeles Has Collapsed
"While humans are killing humans, and governments are spending on weaponry as if there is no tomorrow, the environment is collapsing."
Satellite imagery showing the recent "complete collapse" of the Conger Ice Shelf in East Antarctica sparked fresh alarm over the climate emergency on Friday.
"While humans are killing humans, and governments are spending on weaponry as if there is no tomorrow, the environment is collapsing--so that there will be no tomorrow," said former Greek finance minister and Progressive International co-founder Yanis Varoufakis.
The collapse, as The Guardian and CNET reported Thursday, occurred around March 15.
During that week, an unprecedented heat wave hit the region, with parts of East Antarctica seeing temperatures 40 degrees Celsius above normal. Scientists attributed the "freakish" warming to an atmospheric river.
The outlets pointed to a tweet with satellite imagery shared by Catherine Walker, an Earth and planetary scientist at the Woods Hole Oceanographic Institute and NASA.
Stef Lhermitte of the Delft University of Technology in the Netherlands on Friday shared time-lapse video of the change:
Antarctic ice sheet expert Bertie Miles also provided historical visual context for the collapse:
In a March 17 press statement, the interagency National Ice Center (USNIC) confirmed that iceberg C-38 calved, or broke free, from the Conger Ice Shelf. "C-38 comprised virtually all that remained of the Conger Ice Shelf, which was adjacent to the Glenzer Ice Shelf which calved last week as iceberg C-37," the USNIC said.
Ice shelves, as NASA describes, are "floating tongues of glaciers that extend over the ocean" and "slow the rate at which Antarctica's glaciers contribute to global sea level rise" by holding back the flow of ice into the sea.
At roughly 1,200 square kilometers, according to the reporting, the Conger Ice Shelf was about the size of Los Angeles.
Despite that "relatively small size," said glaciologist and climate scientist Peter Neff, the collapse still represents "a significant event."
Andrew Mackintosh, an ice sheet expert at Australia's Monash University, made a similar observation.
"This ice shelf may have been small but it is in EAST Antarctica, a region previously considered less vulnerable," he said. "It's a wake-up call."
In a Twitter thread responding to the new reporting, Guardian columnist and climate activist George Monbiot pointed to a need for "systemic" changes to address the climate crisis and asked, "How many more warnings do we need that we are facing the prospect of a cascading regime shift?"
"The shift will push planetary conditions into a new state," he continued. "This state will be hostile to the species that thrived in the old one. Species like us."
Monbiot further lamented that climate-related changes remain "at the bottom of the agenda" and asserted that "in retrospect, if there is a retrospect, we'll see the current phase of our slide towards disaster as the least comprehensible of all."
"We knew what was happening. The writing was on the wall," he added. "Yet we carried on opening new oil fields, driving SUVs, leaving homes uninsulated."
Urgent. It's never been this bad.
Dear Common Dreams reader, It’s been nearly 30 years since I co-founded Common Dreams with my late wife, Lina Newhouser. We had the radical notion that journalism should serve the public good, not corporate profits. It was clear to us from the outset what it would take to build such a project. No paid advertisements. No corporate sponsors. No millionaire publisher telling us what to think or do. Many people said we wouldn't last a year, but we proved those doubters wrong. Together with a tremendous team of journalists and dedicated staff, we built an independent media outlet free from the constraints of profits and corporate control. Our mission from the outset was simple. To inform. To inspire. To ignite change for the common good. Building Common Dreams was not easy. Our survival was never guaranteed. When you take on the most powerful forces—Wall Street greed, fossil fuel industry destruction, Big Tech lobbyists, and uber-rich oligarchs who have spent billions upon billions rigging the economy and democracy in their favor—the only bulwark you have is supporters who believe in your work. But here’s the urgent message from me today. It’s never been this bad out there. And it’s never been this hard to keep us going. At the very moment Common Dreams is most needed and doing some of its best and most important work, the threats we face are intensifying. Right now, with just two days to go in our Spring Campaign, we're falling short of our make-or-break goal. When everyone does the little they can afford, we are strong. But if that support retreats or dries up, so do we. Can you make a gift right now to make sure Common Dreams not only survives but thrives? There is no backup plan or rainy day fund. There is only you. —Craig Brown, Co-founder |
