Humans have shown the ability to adapt to climate change before (Little Ice Age or even the real last Ice Age). There’s no reason to believe we won’t be able to tackle global warming.

Will there be some hardship? Yes. Will it be worse than the “nasty, brutish, and short” life most people had throughout history before the 20th century? I doubt it very much.

There is every reason to believe the real cost of climate change will be in the 10s, perhaps hundreds, of millions of lives.

If you want to class that as “some hardship”, that’s your prerogative.
