Phrasing it that way is a little misleading. At 400 ppm CO2 is only 0.04% of the total atmosphere. Increasing from 0.028% to 0.04% is a 42% increase, but 0.04

Phrasing it that way is a little misleading.
At 400 ppm CO2 is only 0.04% of the total atmosphere. Increasing from 0.028% to 0.04% is a 42% increase, but 0.04% is too low to directly poison plants.
The climate change effects will be a problem long before plants and animals start getting poisoned by it.
- ralusek 7y agoIt doesn't poison plants, they rely on CO2 in much the same way that animals rely on O2. I know that it's a negligible part of the atmosphere, but a 42% increase on the primary mechanism for plant respiration, which is also a poison for animals, seems like it would have a meaningful impact.
