How do you unconfound this from being inside in better sealed environments for longer periods now?

Nuclear will save the day in combination with clean tech. Clean tech on its own is too slowly to be meaningfully impactful by the time we need it.
I think you have that backwards. Building nuclear is slow slow slow. I can have new solar on my rooftop this year.
While that is true that there is a lag time to deploy nuclear - that is a vestige of the last 40 years of regulating it out of existence. That has changed - technology has improved and regulatory is under scrutiny. The difference is that once nuclear starts to roll out, as it will in the next 3-5 years, we will be seeing large deployments of clean dedicated load ripple through our electrical system in a product assembly line.
Solar and storage are great assets - and will continue to grow but they have other sets of constraints and deploy at small scale (relatively). The large scale deployments have long time horizons.

It takes ~ten years to build a nuclear generator. In that time, 10TW of solar PV will be deployed at current deployment rates (1TW/year), a bit higher than total global electricity generation capacity currently (~9TW). Fusion is solved, at a distance, with solar, wind, and batteries. Half an hour of sunlight on Earth can power humanity for a year. Long duration storage remains to be solved for, but look how far we’ve…
Fusion isn't in our lifetimes. Its been 10 years away since the 50s - only to get more R&D grant funding for budget building.
If it happened it would be a huge game changer for our economies but it is far away from deployment let along lab proven. It still requires more energy to start/maintain the reaction then it can produce - which is fundamental to success.

Solar and wind are fusion generated energy from the sun. “Fusion at a distance.” Fossil fuels are ancient sunlight, ancient fusion.

There's an oversimplified assumption here that the plants will be less nutritious, and so people will eat more calories to make up for the deficit. I suspect the presence of protein, fats and sugars influence the hormone production regulating appetite far more than these changes account for. I would expect the same health issues to be affecting other animal species in just as drastic a measure as humans if it were tr…
It's not just an assumption, there is research that shows this. For example: https://www.scientificamerican.com/article/as-co2-levels-ris... More specifically, yes, protein content decreases with rising CO2 levels. Maybe not enough to cause obesity on its own, but enough to be a compounding factor. Especially when your staple is, say, rice -- which is what the paper linked above looks at.
The assumption is not the variation in the nutrient counts, but in the link to obesity.
The rise in obesity has much stronger correlating factors than CO2 levels- diet and sedentary lifestyle being far stronger.
This is especially obvious when looking at the cited study:
> The new study evaluated 18 types of commonly grown rice to see how they would respond to elevated levels of carbon dioxide. In the experiments, the researchers increased ambient carbon dioxide levels to concentrations between 568 and 590 parts per million. Currently, atmospheric carbon dioxide concentrations hover around 410 ppm—but at the rate they’re currently rising, they could reach the high levels used in the study by the end of the century, if action isn’t taken to curb them.
The study examines the behavior at levels of C02 we don't currently have. The decline in nutrients has, thus far, been too small to have the impact on obesity we've already observed.

Never heard this take before. Care to elaborate? It seems like crop failure and disease are the typical causes of food shortages, if not outright human logistical failures. Sounds like saying pouring gasoline on a tiny fire is the only reason we aren't cold (ignoring that more firewood would be the solution). An unsustainable solution is not in-fact a good solution. So if your assertion is correct, then we should all…
I think their point is more along the lines of the energy availability of Fossel Fuels allows for the Mass Farming and Construction that we do, not so much that we can pour it on a fire in place of wood.
40–50% of the nitrogen in our bodies come from fossil fuels via synthetic fertilizers.

You're missing the point, which is that by all accounts, Al Gore was a close advisor to Bill Clinton.
And by all accounts, he pushed for action on climate change. As it turns out, close advisors still don't get to set policy.
Another interpretation is that Gore engaged primarily in symbolism.
The Kyoto Protocol itself was primarily symbolic, with little or no enforcement mechanism.

But society needs to progress. We left thatched huts and moved to cities with streets full of human sewage. Humans living together as a society was progress. And then we progressed further and lived together AND removed dumping sewage onto our streets.
