Doomsday glacier

The Thwaites 'Doomsday Glacier' in West Antarctica is spooking scientists. Satellite images shown at a recent meeting December 13th of the American Geophysical Union showed numerous large, diagonal cracks extending across the Thwaites’ floating ice wedge. This is new information, and it’s a real shocker if only because it’s happening so quickly, much sooner than expectations. It could collapse. And, it’s big, 80 miles across with up to 4,000 feet depth with a 28-mile-wide cracking ice shelf that extends over the Amundsen Sea.

Meanwhile, and of special interest because of the underlying threat posed by Thwaites, the Intergovernmental Panel on Climate Change (IPCC) COP26 meeting in November 2021 held in Glasgow was panned by scientists as one more sleepy affair, failing to come to grips with Western Civilization’s biggest challenge since the Huns trampled Rome. This outrageous failure by the world’s leaders, evidenced by weak-kneed proposals, is decidedly threatening to coastal cities throughout the world, especially with Thwaites glacier showing signs of impending collapse.

According to glaciologist Erin Pettit of Oregon State University, the weak spots on the Thwaites ice sheet are like cracks in a windshield: “One more blow and they could spider web across the entire ice shelf surface.”

An article in NewScientist d/d December 13, 2021 discussed the AGU meeting of the satellite images of massive cracks: “Antarctica’s Thwaites glacier could break free of the continent within 10 years, which could lead to catastrophic sea level rise and potentially set off a domino effect in surrounding ice.”

Thwaites is a monster, one of the largest glaciers in the world. A 2017 Rolling Stone article, which followed the footsteps of a team of glaciologists at Thwaites glacier, summed up the situation, according to Ohio State glaciologist Ian Howat: “If there is going to be a climate catastrophe, it’s probably going to start at Thwaites… if we don’t slow the warming of the planet, it could happen within decades.”

That was five years ago but after rapidly changing conditions on the ice sheet in only five years, scientists are no longer saying: “It could happen within decades.” Now the timeline has changed to: “Within a decade,” meaning by 2032. Moreover, as suggested in the aforementioned SFGATE article, there’s some speculation that it could burst wide open “sooner rather than later.”

The world is not prepared for a major disaster on a scale that spreads across the planet unimpeded and totally out of control. In that regard, it’s unfortunate that the world’s leaders have failed to take adequate measures, especially since scientists have been warning for decades of dire consequences for failure to limit and/or stop CO2 emissions.
