I wonder how much of the land is going to become farmable now

I read somewhere that the soil is the problem, not just the local climate. And soil takes a long time to accumulate the good stuff. So in short, places with good soil will become less farmable and places with now better climate won’t have good soil. We’re all kinda screwed then.

"and twice as much carbon as Earth’s atmosphere. " "As levels of carbon dioxide rose from 550ppm to 945ppm to 1400ppm, subjects’ scores under most headings declined substantially. (Problem-solving ability also seemed to suffer as levels of volatile organic compounds rose.)" "2,000-5,000 ppm: level associated with headaches, sleepiness, and stagnant, stale, stuffy air; poor concentration, loss of attention, increased…

Many stressors have an adaptation phase. It is plausible those effects get reduced with prolonged exposure in humans although that wasn't necessarily the case in mice: "Long-term exposure of mice to 890 ppm atmospheric CO 2 alters growth trajectories and elicits hyperactive behaviours in young adulthood"

I'm kind of surprised there isn't more interest in this article. Any big change like this would seem to me to hint at some large effects later on. In Russia alone, the changes have the potential to be huge. I guess it is still kind of "New Year" and people are hunkered down with COVID all over the world.

It's not new news. This idea (i.e., permafrost thaw) has been circulating for quite some time. I'm sure I've read similar at least three times previously, probably more.

Mmm. Modern fertilizer has done a lot to neutralize the importance of good soil. You can't farm rocks, but the US west has done a lot with sand + fertilizer.

As long as you have money, water, sun, heat, and something better than bedrock, I wouldn't call it unrealistic.

The Newsroom said it best, "your house is burning to the ground, the situation is dire; your house has already burned to the ground, situation's over." [1]

I don't see a way that we plausibly reverse course, when nearly every government, the people running them, and the private sector leaders are all just doing an end-run to accumulate as much as they can, planet be damned. Every "climate target" gets re-evaluated and pushed back every five years, and nobody seems to be held accountable for it.

Barring moonshot tech breakthrough or militant scaling-down of consumption worldwide, how can we survive?

I found this to be so fascinating, "At a certain point, nature takes over. Even the most forward-thinking legislature in the world can’t pass a law banning emissions from permafrost."

Solar geoengineering could potentially stop further thawing: https://en.wikipedia.org/wiki/Solar_geoengineering

Soil is not an essential piece to growing crops. Even now hydroponics is taking off in many places.
