Unpopular prediction: we're going to solve global warming by the 22nd century, but we're going to "solve" it with nuclear winter and the destruction of 80-90% of humanity. Once we're down to a billion people or so and most of what passes for advanced civilization has been destroyed, carbon emissions and warming won't be a problem.

Nuclear winter seems unlikely to me, and from what I understand I'm not alone. Cities are no longer prone to huge firestorms like they once were. Furthermore most nuclear strikes would probably be airbursts to maximize blast effects, but that means less material being thrown into the atmosphere. If the attack were calculated to cause maximum fallout instead, airbursts of salted bombs might be used, which would poison…

The primary targets for nukes aren't cities, they're other nukes. Most of these warheads are set for groundburst (or underground burst - I remember a bunch of research in the 80s about burrowing/penetrating warheads), because to blow up a 3-4 foot thick reinforced concrete silo you basically need to land right on top of it. That's the big fallout threat.

Well, I'd welcome the idea of once a year total shutdown for a couple weeks: no cars, no economic activity, except maybe hospitals and other infra. That would be a sort of worldwide retreat. I still remember how clean the air felt the first time the us did a hard shutdown (empty roads, people were scared). I'm sure the capitalists will hate the idea to halt the factory for 2 out of 52 weeks.

The biggest takeaway here for me is that we collectively achieved something previously considered impossible: by making different behavioral choices, as a species, we achieved the largest cut in CO2 emissions in 75 years. It's tragic that only the threat of a deadly disease could compel such a change, but perhaps we may find other levers to help us achieve such widespread beneficial changes in the future?

All it does it prove how fruitless the prevention of climate change is. A total shutdown of the entire world economy on an unprecedented scale still doesn't track enough to prevent climate change. If that isn't a clear indicator of how severe the situation is then I don't know what else is.

Actually I think my view on climate change is more optimistic now. The article mentioned the majority of the carbon reduction wasnt actually due to reduced demand, but rather from lowered emissions from using renewables (and more specifically the closures of coal plants). This seems like pretty good news to me. You can continue to grow and operate the economy while reducing carbon emissions to levels they need to be at by switching everything to renewables.

For a lot of people it was their only alone time.

I only listen to podcasts while driving, so my "learning" time has been drastically reduced

I noticed this problem. I read during my commute (it was by train don't worry), and since I've started working from home my reading time has absolutely tanked.

Same here, I'm way behind on podcasts. The only time I listened to them was when I was driving.

Why not set aside some time each day to listen? Take a bath, lounge on the couch/hammock, and enjoy that time not commuting.

I have two young kids. There is no such thing as "lounging". :)

If there was no threat, it would not have happened.

But we have handled ammonia on an industrial scale for more than a century and are really good at it. Any safety concerns about ammonia are ridiculous when compared with some of the other substances we handle and live around on a daily basis.

A a John Deere employee I can tell you that several very much wanted products have failed to be developed because someone put their safety black-hat on and came up with a to abuse that product the release ammonia into the air. Once an evil person figures out how to control our system it is trivial for them to figure out many terrorist attacks involving ammonia releases. Yes the world deals with ammonia all the time.…

Please be specific. Liquid anhydrous ammonia is a common fertilizer. John Deere still sells e.g. the 2430 and the 2510. How did the hypothetical "very much wanted" products differ from those applicators? Are we talking about a handheld model? (That might have been a bad idea!) One suspects the hypothetical "evil persons" whose threat delayed product development were more interested in cooking meth than in terrorist attacks...
