Plants LOVE CO2. If you take any modern plant and put it in a CO2 rich environment, it'll grow faster. Ask any pot grower.
Plants evolved when there was more CO2 in the atmosphere than now. We're going back to that era, because we've burned all the coal and oil that was laid down over millions of years back then. LISTEN: it took millions of years for that CO2 to be removed from the air, and we've put it all back in 100 years. THERE WILL BE CONSEQUENCES. It's too late to do anything. Politics be damned. Unless we start removing CO2 from the air (which costs money nobody wants to pay) costal cities will be flooded, coral reefs will die, and it'll take MANY THOUSANDS of years for life to recover. This is just fact. You already screwed us, thanks.
