[Emphasis mine]

He literally did say that, unless you think "would not sustain human life" is compatible with "habitable". That quote was an asinine statement to make and only serves to provide ammunition to those who want to convince people that climate change is not a real problem.

Imagine if I were to say "the last time that large amounts of people walked around in suits on daily basis, we had two world wars!". This is both true and misleading.

No scientist believes that climate change will cause such sire circumstances.

The experts on the matter believe that sea levels will rise by a meter or so over the next hundred years.

If you believe that this will end the world, then you should know that the experts disagree with you, and that you should go read some more science.

So yes, it is true that "the last time C02 levels were at this level, the world could not sustain life". But it is also misleading as it implies causation.

The scienctists do not believe that these levels would cause mass extinction of human life. The badness is closer in scale to another Iraq war.
