And at the same time we have populist leaders of more and more countries flat out calling climate change a hoax. This is a dangerous combination. At the point where the general public finally accepts that imminent change is required to avoid disaster it may already be too late for that change to have enough impact.

Sticking point is usually man made or not.

Climate always changes. We are coming out of an ice age.

Hot Question is how much is industrial activity contributing.

Even shutting everything down today will not stop climate change. But what would happen to the rate of change?

Solutions can run into trillions, for unclear results.

Sure, but in the public debate "climate change" means "man made climate change" because the non-man made part is tiny compared to the man made part.

Its size alone is staggering. I'd be interested to find out the scale of the changes we would need to enact to stop it `teetering` over the edge.
