23,000 year old human foot prints found at White Sands NM, alongside those of now-extinct animals like mammoth and dire wolves. People were definitely on the continent during the height of the ice age.

Japan is actually going ahead with a controlled release of cooling water from the Fukushima reactors.

I occasionally watch a YouTuber over there and if his videos are any indication the area is still in rough shape and still patrolled.

Even knowing that the older shit occasionally goes wrong, and humans are gonna f*ck up, the older shit produces so much power with so little environmental damage (including the accidents), that nuclear should be considered as a power source. E = mc^2 is far far more energy productive than chemical reactions or diffuse renewable energy.
They say a coal plant would never be licensed by the NRC because it releases too much radiation. (Dunno if that includes accidents)

Don't you think accidents at coal plants would be pretty acceptable if increased radiation was the only concern? Probably a really telling stat.
These old nuclear plants should all have catch basins under them, shaped to disperse the fuel enough act like un-refineries without letting anything leak lower. Before the accident, the solutions are a lot simpler than convincing anyone to implement them. After the accident you gotta drip gold in there.

This is fascinating. From the event, to the analyses, to the conclusions, to the potential oral tradition that was recorded in the Bible to the reminder of the intensity and length of dense human occupation in some areas of the world.

The fact that there are two cases of human settlements being destroyed by meteors is humbling.

So there's been two in ~5,000 years of recorded history. Or one about every 2,500 years on average. And it's been how long since this latest event?

The more likely landing spot being an ocean, do tsunamis count?

I took that to mean two cities destroyed, not megaton-scale airbursts. Presumably there have been a lot more of the latter. We certainly know about every single one that has happened since the dawn of the nuclear age.
Airburst wouldn't create a tsunami, I assume. It is interesting to wonder how many oceanic impacts may have happened that created locally- or regionally-significant tsunamis but didn't create global effects.

I lose more sleep at night worrying about the planet destroying things lurking "nearby" in the galaxy/universe than local bad shit that you at least have a chance of getting out of the way of. I still sleep pretty well, though.

Coronal Mass Ejection? Yeah, me too. Although far less likely, something about Gamma Ray Bursts also make me uneasy.
