Apparently CO2 and warm temperatures aren't so devastating after all.
Only if you are a Rat and trying to soak the gullible public for votes, power & tax dollars!
Re: “CO2 was 7,000 ppm”
I wish your excellent graph showed CO2 levels further back in time.
It’s my understanding that “Snowball Earth” peaked about 650 million years ago.
Do we have any CO2 data from that earlier, frigid point in Earth’s history?
