The Gemini crew reported they couldn't actually feel any gravity, all they could observe was that objects in the capsule slowly moved towards the outside of the tether-system.

A full 1g is probably not necessary, but how much is, that's the big question. Unfortunately we're not really in any position to produce e.g. .8g for a prolonged (read: several months) time to see whether this has any negative effect on the test subject.

That is easier said than done. To actually make this work without getting the person subjected to it sick (due to differential gravity between head and toes, so to speak), that ring would have to be HUGE.

There were some experiments with artificial gravity done by Gemini 11, they attached a tether to their AGENA docking target and started rotating with it. The gravity generated was in the 0.0001g ballpark IIRC, though. This would probably be far more realistic to do, i.e. creating a capsule and a counterweight and spinning them about each other, because you need way less mass and you could easily put capsule and counterweight at a huge distance and rotate them slowly while still generating a reasonable amount of gravity. The problem is that the cable to connect them has to be made out of something that's better at not ripping than anything we can manufacture right now.

Artificial gravity by rotation look cool on paper, it's the little problems that keep it from happening.

Life on this planet will continue. Maybe without homo sapiens, but maybe that's for the better for life on this planet.

Life has mastered many other and far more serious threats. Remember the Oxygen catastrophe? That was horrible! And not in the "oh no, like 3000 of the 8 billion people we have died" way we think of catastrophes today, we're talking about an event that caused Earth's temperature to fall by significant amounts (not the piddly crap we're worrying about today, 1-2 degrees, pffffft!), and all because those damn plants had to produce oxygen!

And that was only the first (and maybe not even the first) of a long, long line of disasters and catastrophes that beset life here, often wiping out 90% or 95% of all species! Yet always enough remained to keep the system going.

So why worry? Sure, it will as usual cost the apex predator, but then again, life doesn't really give a shit. Why should it, if not even said apex predator does?

Did they place it next to the 401, or did they place the 401 next to the weather station?

There are a few weather stations in my home country (and during my studies I had to deal with them a lot), some of them having been in place for centuries, and many of them in rather unfortunate positions, mostly because when they were established it was a necessity to put them close to where people lived (so you could get there on foot), without considerations for projects that were decades or centuries in the future.

Moving those weather stations isn't a good idea either, though, because by taking readings where they are, you get a very good instrument for examining change over time. Moving the weather station would destroy that ability.

Of course such changes in the environment have to be taken into account. If you had a weather station in the middle of a sunny, grassy hill and a huge skyscraper is built in front of it so it's now permanently in the shadow of said building, it doesn't mean that the average temperature dropped by 5 or even 10 degrees Celsius.

Environmental impact on the weather stations have to be taken into account!

Because it's easier on their mind.

Let's be honest here, if we wanted to do something about global warming, we'd have to change our way of life. And we'd have to change it big time. We (Europe and the US) use up more resources than the rest of the globe combined. Yes, including China. But they're trying to catch up. Should they ever reach us, it's game over anyway. That this isn't even sustainable in terms of resource usage, not to mention waste production, is, at least to me, obvious. If you disagree, do so, I don't give a shit.

So if you admit that global warming is a reality, you can do two things: Either feel guilty about continued overusing resources or reduce your consumption. Either is not really something people want to do. The first makes you feel bad (and we all know how troublesome this is to the fragile souls of our millennials) and the latter inconveniences you.

So it's easier to just wish it away and say it ain't happening.

Personally, I found a third way. I simply don't give a shit about it anymore. Yes, I'm convinced that global warming is real, the data I have available points to yes. But so be it. I won't live another 50 years, so I don't give a fuck.

If you want to save your planet, go ahead. Hell, I'll even move along. But don't expect me to waste any more of what's left of my time on trying to convince people that they have a duty to their kids. If you don't give a shit about your kids, how could you expect me to?
