So the earth had CO2 levels 5X today’s and temperatures 9 degrees hotter on average, and it survived? It also readjusted without any cap and trade laws. If that’s true, then what’s the whole climate crisis about? We don’t have to do anything. It’ll fix itself...or maybe the cooling will be a bigger problem. Ice ages aren’t nice to humans.

I'm pretty sure it had been over ten times today's levels.
