Antarctic 'Doomsday Glacier' Melting Faster, Scientists Warn 45
A massive Antarctic glacier, dubbed the "Doomsday Glacier," is melting at an accelerating rate and could be approaching irreversible collapse, international researchers are reporting. The Thwaites Glacier, holding enough ice to raise global sea levels by over two feet, has seen rapid retreat in the past 30 years.
Scientists from the International Thwaites Glacier Collaboration used ice-breaking ships and underwater robots to study the glacier up close since 2018. Their findings reveal warm ocean water funneling through deep cracks in the ice, causing unexpected melting patterns. While computer modeling suggests catastrophic cliff collapse is less likely than feared, researchers project Thwaites and the Antarctic Ice Sheet could disintegrate within 200 years. This collapse could ultimately lead to 10 feet of sea level rise, devastating coastal communities worldwide.

When I moved home a couple of years ago, I made sure my new place is at the top a hill. Whilst sea level rise is still a long way off, higher global temperatures means more water in the atmosphere and more flooding events around the world.
Your local area should publish a floodplain map, I’d suggest being at least a couple of metres above the 100 year level if you can.

You have to understand they're following the 80's Club of Rome document on how to control a world-sized population. PDF is online (archive.org etc.)
The key idea is "Man is the Enemy of Man".
They suggested: man-made Global Warming, man-made Financial Crises, man-made pandemics.
So, it's probably untrue but the key economic insight, per your observation, is that all the money spent on prevention could be spent on adaptation and prevention money is worth zero in your scenario. So Opportunity Cost disaster.

Re: (Score:2)
You really can't say which change, because it differs from place to place. Some places should expect increased flooding, other place increased droughts, etc. So far one of the main changes is the jet stream becoming slower and more unstable, but most people can't measure that directly, what they can notice is that rainly patches often remain in place longer. Ditto for dry patches. And the season at which some things happen has been changing. (Like caterpillars showing up early, but not the birds that u

My guess is those are two predictions for different degrees of melt, probably at different time-points, but possibly also using different bounds for "what's in the glacier?" or "how thick is it?". Or possibly "what secondary effects are included?". The story's from CNN, and sometimes their science reporting is a bit confused.
Re: (Score:3)
The Thwaites Glacier melting would lead to about 65cm of sea level rise. The higher figure is likely based on this collapse destabilizing the entire ice sheet over West Antarctica.
I think the more concerning thing is that the rate of change in reality is streaking out ahead of what the models predict.
