That's straight up bad information. Climate change isn't a yes or no, it's a matter of degree.

Serious consequences are unavoidable, and we urgently need to start adapting. But we absolutely can and should mitigate climate change itself to avoid some more extreme consequences.

Don't go around telling people there's nothing we can do, there's still time to make a difference and we should focus on positive actions on individual and societal levels.

Also, the jury isn't out, people are already taking effective action to adapt in the real world.
