@LukeAlmighty Thing is, if we lose enough technology or energy output, we simply won't be able to make us of nuclear material anymore. We won't have enough resources to build and ignite a nuclear power plant.
As for fusion... no... we've been "a decade away" for how long now? And we're still "a decade away". Best estimates are for a TEST production facility for 2040 I think. Which means, there's still far off from widespread adoption. And that's of course assuming the test goes well, and there isn't another Greenpeace social panic that sabotages everything... again. I'd rather maintain zero hope for fusion and be pleasantly surprised if it does happen. Fission is a known quantity, and we should have had a fission power plant at every corner by now (figuratively speaking).
Global warming is a bit more complicated than that, but I was trying to avoid the topic altogether. The whole sea level rising issue has been horribly explained by the media for as long as I lived. And now that I finally had someone explain it properly... yeah... it IS happening, and no EU "carbon plan" will stop it.
