This thread is just to post interesting news, thoughts, opinions about climate change.

They'll never admit it.

Huge cavities threaten glacier larger than Great Britain

British scientists have mapped cavities half the size of the Grand Canyon that are allowing warm ocean water to erode the vast Thwaites glacier in the Antarctic, accelerating the rise of sea levels across the world.

Like decay in a tooth, the channels of warm water are melting the ice from below, threatening the stability of a glacier that is larger than Great Britain.

Using an aircraft, ship and robot submarine, the British Antarctic Survey and a US team traced the seabed terrain and the bottom of the ice shelf to measure the gaps that have opened between previously grounded sections of the glacier.

They measured two old cavities that were roughly six miles (10km) across and 800 metres deep, which allow warm water to seep under the ice. These have formed over at least 10,000 years. In addition, they mapped several new, thinner fissures that have branched off from these main trunks amid the warmer temperatures of the past 30 years.

The results were published this week in the Cryosphere journal. The good news is the new channels are not yet as large as had previously been assumed, which suggests the collapse of Thwaites may not come as soon as feared. The bad news is scientists believe the cavities are widening but they do not know how fast.

“Before we did these studies, the assumption was that all the channels are the same, but the new ones are much thinner and more dynamic. They will get bigger over time,” said one of the lead authors, Tom Jordan, an aerogeophysicist at the British Antarctic Survey.

“Understanding that process and how these cavities evolve will be key to understanding how Thwaites and western Antarctica will change in the future.”

Great write-up in NYT on displacement coming for the US.

Spoiler alert: You thought the Dust Bowl was bad...

Just finished reading that. Woof. Glad I am in the midwest.

All the Californians moving North into Oregon had a fun surprise this last week.

But it's an artisanal fire they just can't get back in LA.

I can't help but laugh. I do love black humor. Smokey, black humor.

I laughed, but in all honesty it's also not funny. It's awful here now. I never truly felt "trapped" during the Covid lockdowns, but now I truly feel trapped.

What I couldn't gather from the article, but was wondering about, is how those Midwest areas are going to get impacted.

If, as the article implies, climate change pushes more population that can afford to move into megalopolises where resources will be more expensive, the less populated places will suffer more and more. Richer folks with more marketable skills will flee communities in Arkansas, Missouri and Iowa for Chicago, Minneapolis and Detroit. Those left behind in AR/MO/IA will have a smaller tax base, worse infrastructure and declining crop yields (the last one from macro climate change, nothing to do with rich, educated consultants leaving their second homes).

The article argues that the PNW and NE will gain pop...at the expense of rising infrastructure costs (to incl water, electricity, services, transpo, etc.).

That's very fair.

So it will be the opposite of the movie "The Day After Tomorrow"?

That movie was terrible for climate change activists. It was absolutely ludicrous and pushed me further in the climate change denier direction,
