.036% of the atmosphere is CO2, most of it existing already, yet we are the idiots for doubting global warming?
I like to put it this way...
Anthropogenic Global Warming in two sentences:
If CO2 makes up 3/10,000 of our atmosphere, we can skip through sustainable meadows with unicorns.
If CO2 makes up 4/10,000 of our atmosphere, the planet will be wrecked and at least a billion people will die.
Makes lots of sense, don’t it. BTW, there’s less CO2 in the atmosphere than freakin’ argon.
