  Ridiculous statements like this do not encourage people to take the real serious problems of global warming seriously. It's a crisis which will be a catastrophe, but under no plausible endgame is extinction for us.

    I for one hope that Humans might push back climate change.
    - lobocinza 5y ago
      More likely that we adapt to it. There's nothing we can do once things get out of control on a planetary scale.
  - adrianN 5y ago
    Well yeah, humans can survive underground huddled around breeder reactors for hundreds of years. It's pretty hard to get us extinct. It's imho a lot easier to destroy modern civilization as we know it. Widespread wars for water and arable land could totally do it.
