Well lets say natural global warming will cause a rise of 5°C in the next 50 years. Then we have 50 years to adapt. But when we accelerate this change we might need to adapt in 5 years. And we might even cause a rise of 6°C instead of 5. I believe those are the big problems we are facing.

I think in that case we would focus on ways to cope with climate change. For example, air conditionning everywhere would make sense. What's difficult about the current crisis is that you can't use too much energy to fight it without making it worse.
