The OP is mistaken. It is easier to compare PPM numbers.
At 150 PPM and lower, plant growth shuts down (not at 200 PPM as in title).
During the last ice age, which peaked approx.18,000 years ago, CO2 got down to 180 PPM. That was a close one...
Most CO2 is stored by the oceans. Once temperatures started to warm up in the interglacial starting around 11,000 years ago (give or take the Younger Dryas period), CO2 went up to 280 PPM from the warming oceans... one of the strange characteristics of water is that cold water is able to absorb and store more CO2 than warm water.
The fact that it is now approx. 400 PPM is a very good thing. Greenhouses keep their CO2 at around 1100 PPM to maximize plant growth. That is something to shoot for...
Well it is considered beyond the precipice by some climate change scientists by crossing over 400 PPM or the "no point of return" aka "uncharted" territory for humanity.
But we all know that the last time 400 PPM of carbon gas happened the earth was very lush green.
Wow
I thought it was taking over! Like 40% or something!
.02?? That’s just dumb.

400 parts per million is exactly 04%
I am not wrong. Those are equal.
