Within broad limits, CO2 is plant food. Raising the atmospheric levels from .004% to even .006% would have negligible impact other than more greenery.
Right now there's a billion dollar project in Scandinavia meant to pump CO2 from our atmosphere deep back into the ground - about a mile because of current technological limits - yet "60 Minutes" played that up like they're saving the planet. Never mind that lighter than oxygen gases will eventually rise no matter the obstacle - Libs will feel better believing they've saved us all! (while their backers reap profits from idiots believing their lies).
This is what we get from education systems that push propaganda over useful knowledge.
