ice apocalypse

So will it be fire or ice that gets us. Eric Holthaus, writing in Grist, says ice.

The glaciers of Pine Island Bay are two of the largest and fastest-melting in Antarctica. (A Rolling Stone feature earlier this year dubbed Thwaites “The Doomsday Glacier.”) Together, they act as a plug holding back enough ice to pour 11 feet of sea-level rise into the world’s oceans — an amount that would submerge every coastal city on the planet. For that reason, finding out how fast these glaciers will collapse is one of the most important scientific questions in the world today…

In the past few years, scientists have identified marine ice-cliff instability as a feedback loop that could kickstart the disintegration of the entire West Antarctic ice sheet this century — much more quickly than previously thought.

Minute-by-minute, huge skyscraper-sized shards of ice cliffs would crumble into the sea, as tall as the Statue of Liberty and as deep underwater as the height of the Empire State Building. The result: a global catastrophe the likes of which we’ve never seen.

I enjoy Eric’s writing. He employs some hyperbole, but always links to original sources you can drill into if you want to. Regarding the hyperbole though, here is some criticism of him in the Guardian:

I was particularly concerned about some of the implied time scales and impacts. That ‘slowly burying every shoreline…creating hundreds of millions of climate refugees…could play out in a mere 20 to 50 years’ (it could begin then, but would take far longer). That ‘the full 11 feet’ could be unlocked by 2100 (Rob and Dave predicted the middle of next century). That cities will be ‘wiped off the map’ (we will adapt, because the costs of protecting coastlines are predicted to be far less than those of flooding). We absolutely should be concerned about climate risks, and reduce them. But black-and-white thinking and over-simplification don’t help with risk management, they hinder.

Is “the entire scientific community [in] emergency mode”? We are cautious, and trying to learn more. Climate prediction is a strange game. It takes decades to test our predictions, so society must make decisions with the best evidence but always under uncertainty. I understand why a US-based climate scientist would feel particularly pessimistic. But we have to take care not to talk about the apocalypse as if it were inevitable.

Maybe, but if the cost of protecting cities is less than the cost of flooding, perhaps our U.S. politicians could get to work on that instead of continuing to bury their heads in the sand and pretend science doesn’t exist, even if the time frame is uncertain. Remember the serious scientists are arguing here over whether the most likely scenario is the one that has been presented over the past few years, or something worse. They are not arguing that it might actually be better than they thought.

your very own doomsday bunker

Do you want a doomsday bunker but you are not sure how or where to build one? Now you can buy one (er, lease for 99 years…) already fitted out in South Dakota. The only question I have is, how will I get to South Dakota quickly when the missiles are incoming? I guess I could just move out there and live nearby. But if I am going to do that, I might as well just go ahead and move into the bunker. Once I am in the bunker, what will I do all day? I suppose I can count my guns and gold bars. But that might get old. Do they have cable? Come to think of it, I have a few more questions. Is there a water well? Is there a wastewater treatment plant? Is there a power plant? Is there a Walmart? After thinking this through, I think I’ll just take my chances here in civilization and hope the end is quick.
