I was randomly reading up on artificially increasing #CO2 levels in growing spaces, and found this: https://www.ontario.ca/page/supplemental-carbon-dioxide-greenhouses

"Ambient CO2 level in outside air is about 340 ppm"

That didn't sound right to me...

Oh, wait, that was 2002.*

We're over 420 ppm now.

Yikes.

Can't believe people with the power to make changes are doing basically fuck all.

* Their number seems a bit low for 2002, another source I looked up says 370... but that's not really any consolation!
