Read the article. Look at the chart. The seasonal fluctuations are much, much less significant than the rising trend.
> Cause plants breath it in during sprint and exhale it out in fall (I don't remember if this is correct, or just my own misguided idea).
Plants absorb CO2 to grow, making leaves, branches, plant material and whatnot. In the fall, leaves fall off trees, grasses die, and are metabolized by fungi and bacteria, releasing CO2.
- Buttons840 5y agoI don't know why were speaking as though we disagree about something. I agree with everything you said. I have my own CO2 meter inside, which I watch with some curiosity. I've observed that CO2 levels vary far more where my sensor is located, inside in an urban environment, and I was surprised to see that the CO2 levels are so steady elsewhere. [1] measured CO2 levels in an outdoor urban environments and found that sometimes the CO2 levels were about 20 times what they were at other times, 16 units vs 0.8 units. I say this as a curious observation, not as an attempt to argue against anything you said.
