I'd think that a lot of what you'd do to 'stop' climate change would be one and the same as 'mitigating' it, and we'll be forced to do both - transition to clean energy AND deal with consequences.
No, not remotely. Climate change is impacting both fire and water and hurricane related insurances. Managing that isn't reducing emissions. We need more medical staff and staging for heat stroke in the south (and the north during La Nina years). This stuff is with us for a bit whether humans act or not (they won't at least not at any pace good enough to matter).
To me, what we're seeing now is a limitation of human society. For quite a long time many of us held a belief that people are all-powerful and invincible, but climate change is shattering that illusion. It's just not true. In the past ten years or so I've likely read about 300 academic books on world history, sociology, anthropology from across the past century. Guess how many of those made any mention at all of our impact on the environment?
That we're an intrinsic part of a biosphere just didn't enter our collective consciousness until it was way too late.
Actually it got there in the 1960s with the clean air and water acts. But 15 to 20 years later, a bunch of neocons derailed America. And now we have true believers that think what is happening is a lie.
