Love it when it snows

"This is why greenhouses add CO2, to increase plant growth and reduce water needs."

Elementary school teacher did a good job.

High school teacher seems to have cut some corners, though.

Let's keep this thread on topic, I think what they're trying to say is it's  all a big snow job. 

I don't  know about other universes but this one isn't  cyclical,  it began with a bang and will end with a whimper. 

On a more serious note, and not taking sides in the global warming argument, is anyone surprised that millercarbon is rooting for more carbon (dioxide)?

Be honest, wouldn't you, too?

The fact that other countries pollute is not a reason to not stop polluting it's another bogus argument. You have to start somewhere so start at home. Greta Thunberg and her fellow young people, and likely some of your kids and grand kids will need an earth to live on clean air to breathe and clean water to drink. Believe what you will but climate change is not about us it's about them.

This is not virtue signaling this is life and death and the future.
