I got to witness a small glacier dam burst in the Wind River range of Wyoming. The amount of power released by even a small lake is unfathomable. It sounded like a 12-lane highway even from a mile away. Can’t imagine the destruction of a big glacier lake.

And Arkansas and Illinois. Finding large tracks of land for sale that hasn’t had some part of it enrolled in a wetlands or conservation easement is getting more and more difficult. (Also, this will be a large problem in the future. Forever use bans is not best productivity or ecology.)

So you're saying the rest of the world just needs to have a calm talk with The United States and lay its consumption out in a rational way. Everyone will see the need to change their lifestyle to save the planet.

I was merely pointing out that being overweight had nothing to do with his situation. Being overweight isn't going to win health awards, but you can limit your calories and still be a train wreck inside.

This is patently false. Name me one nuclear accident not named Chernobyl or Fukushima where the reactor failed and lead to widespread contamination or verifiable health issues in the surrounding areas.

Chernobyl was a perfect storm of corruption, extremely poor reactor and containment design, and lax safety standards. Fukushima was caused by collusion, corruption, and inept management between the government of Japan, the regulator, and TEPCO.

Modern reactor and containment design are miles ahead of Chernobyl and Fukushima, and all reactors are designed around negative coefficients to prevent a possible catastrophic failure

Basically coal contains trace amounts of radioactive elements and those radioactive particles are spread when the coal is burned and the waste gases are dumped in to the air.

1993 article mentioning it: https://www.nrc.gov/docs/ML1002/ML100280691.pdf

2007 article mentioning it: https://www.scientificamerican.com/article/coal-ash-is-more-radioactive-than-nuclear-waste/

A Canadian company wanted to buy up all the coal that was sitting around to extract radioactive isotopes from it and turn it in to nuclear fuel, when the coal companies found out about it, they immediately squashed the sale because of potential optics surrounding coal-fired power plants and the release of radioactive material. I'm trying to find the article that talks about it, but it's been a while since I read it

Natural gas started replacing coal due to fracking making it cheaper. This started several years before wind and solar were competitive. Now all three are killing coal, but as wind and solar keep getting cheaper, less of it will be natural gas (14% this year for new NG in the US).

> We'd basically have to build one nuclear power plant a week for the next 25 years.

The world installed an estimated 268 GW of solar in 2022. Assuming a 20% "capacity factor" (actual average output accounting for night and weather) that comes to 53.6 GW average power. Note: US average capacity factor for solar is 24.4%, but not everywhere is so sunny.

A typical size for a new nuclear plant is 1 GW, so that is 53.6 nuclear plants, slightly more than one a week. It is just solar uses a fusion plant that is safely located 149.6 million km away.
