Understand, Andy, I'm not saying it is a problem. I'm not saying it isn't serious.
A crisis is an infection. Ebola. Flu. You get sick fast, you either get over it and get well, and you go back normal. Or die.
A long term problem is Diabetes. At first, you don't notice anything, only a careful measurement of blood sugar shows that there is a problem. Eventually after years to decades, it can kill you, if you don't take measures to lower blood sugar. Even if you do, you need to maintain and perhaps increase those measures for the rest of your life. You never get back to "normal".
Climate change is a long term problem, not a crisis.
If you don't understand the difference, don't bother trying to make climate change into a crisis. It isn't one. I'm not saying it is a problem. I'm not saying it isn't serious.
