Ford are wrong, and history will prove it.
The house building companies already have vast amounts of land they own with planning permission in place. They restrict the amount of housing they build to artificially keep the prices high, if they build too many, the prices they could sell their houses for would drop, reducing profit. These are private companies and the government has little control over them. This is why every government for the last few generations has promised more houses and delivered nothing.
100,000 people marched through London at the weekend at the Restore Nature Now March, and there was virtually no news coverage of it. Yet 2 people spray corn starch on a monument and it's front page news globally.
It's a dilemma.
Sorry I didn't get a paywall. Text here:
A couple feet of sea-level rise may not sound like a lot. But if sea levels rose by 2 feet worldwide, the effects on coastal communities would be catastrophic.
Cities such as New York, Miami, and New Orleans would experience devastating flooding. Across the globe, 97 million people would be in the path of rapidly encroaching waters, putting their homes, communities, and livelihoods at risk.
That's what would happen if the Thwaites Glacier, nicknamed the "doomsday glacier," collapsed. But it wouldn't stop there.

Right now, this massive Antarctic ice shelf blocks warming sea waters from reaching other glaciers. If the Thwaites collapsed, it would trigger a cascade of melting that could raise sea levels another 10 feet.
Already, the melting Thwaites contributes to 4% of global sea-level rise. Since 2000, the Thwaites has lost more than a trillion tons of ice. But it's far from the only glacier in trouble, and we're running out of time to save them.
That's why geoengineers are innovating technologies that could slow glacial melting.
The latest strategy is curtains. That's right — underwater curtains. John Moore, a glaciologist and geoengineering researcher at the University of Lapland, wants to install gigantic 62-mile-long underwater curtains to prevent warm seawater from reaching and melting glaciers.
But he needs $50 billion to make it happen. Drawing the curtains on glacial melting
One of the main drivers of glacial melting is the flow of warm, salty sea water deep within the ocean. These warm currents lap against the sides of the Thwaites, for example, melting away the thick ice that keeps the shelf's edge from collapsing.
As oceans warm because of the climate crisis, these intruding currents are set to increasingly erode the Thwaites, driving it closer to total collapse.
Moore and his colleagues are trying to figure out whether they could anchor curtains on the Amundsen seafloor to slow the melting.
In theory, these curtains would block the flow of warm currents to the Thwaites to halt melting and give its ice shelf time to re-thicken.

This isn't the first time Moore has suggested this blocking solution. His curtain idea is based on a similar solution he proposed back in 2018, which would block warm water using a massive wall.
But Moore said curtains were a much safer option.
He explained that they were just as effective at blocking warm currents but much easier to remove if necessary.
For instance, if the curtains took an unexpected toll on the local environment, they could be taken out and redesigned.
"Any intervention should be something that you can revert if you have second thoughts," Moore said.
While Moore and his colleagues are still decades away from implementing this technology to save the Thwaites, they're in the middle of testing prototypes on a smaller scale. A $50 billion idea
Moore's colleagues at the University of Cambridge are already in the very early stages of developing and testing a prototype, and they could progress to the next stage as early as summer 2025, according to Moore.
Right now, researchers at the University of Cambridge are testing a 3-foot-long version of this technology inside tanks. Moore said that once they'd proven its functionality, they'd move on to testing it in the River Cam, either by installing it at the bottom of the river or by pulling it behind a boat.

The idea is to gradually scale up the prototypes until evidence suggests the technology is stable enough to install in the Antarctic, Moore explained.
If all goes well, they could be testing a set of 33-foot-long curtain prototypes in a Norwegian fjord in about two years.
"We want to know, what could possibly go wrong? And if there's no solution for it, then in the end, you just have to give up," Moore said. "But there's also a lot of incentive to try and make it work."
With scaling comes an increased need for funding. This year's experiments are set to cost about $10,000. But to get to the point at which Moore and his colleagues could confidently implement this technology, they'd need about $10 million.
And they would need another $50 billion to actually install curtains in the Amundsen Sea.
"It sounds like a hell of a lot," Moore said. "But compare the risk-risk: the cost of sea-level protection around the world, just coastal defenses, is expected to be about $50 billion per year per meter of sea level rise."

While some coastal cities, such as New York, have the budget to adapt to rising seas, others won't even come close.
"One of the great driving forces for us is this social-justice point — that it's a much more equitable way of dealing with sea-level rise than just saying, 'We should be spending this money on adaptation,'" Moore said. A race against time
Data shows that the Thwaites lacier, and others like it, are melting at unprecedented rates because of the climate crisis. But the question of when they could collapse remains up for debate among glaciologists.
"We really don't know if [the Thwaites] could collapse tomorrow, or 10 years from now, or 50 years from now," Moore said, adding: "We need to collect better data."

But collecting better data would take time that these glaciers may not have.
Proponents of glacial geoengineering research, such as Moore, believe the time for intervention is now. Other experts disagree, arguing that cutting carbon emissions is the only viable way to slow glacial melting.
While reducing emissions is essential for mitigating the effects of the climate crisis, Moore isn't confident we'll cut back drastically or quickly enough to save the Thwaites. Once it reaches a tipping point, "the glacier doesn't really care anymore about what humans want to do about their emissions," he said.
"At that point, that's when you need these other tools in the box."

So Ilya has signed a letter saying if he doesn't resign he'll quit?!?
Is this embrace or extend? I'm not looking forward to extinguish.
Looks like OpenAI split in two and Microsoft ended up holding both pieces. Impressive work really.
