It's the abundance of carbon in the atmosphere that allows all plant life to flourish
Hello GZ,
You are right of course... except maybe for the second statement in your message.
Too much CO2 is not better than not enough. There is that preferred level which is around 240ppm, the level we have enjoyed as Homo Sapiens. We are now at above 400ppm. The last time the CO2 concentration was that high, is when our ancester Homo Habilis first appears on our planet in the early Pleistocene, some 3 millions years ago.
Here is a google translate from one of the many sources about this topic that I consulted.
"It was therefore 3 million years ago, during the Pliocene, that the concentration of carbon dioxide exceeded 400 ppm for the very last time. During this period, temperatures were then 3 to 4°C higher and trees were growing in Antarctica. The level of the oceans was 15 to 20 meters higher. This CO2 had been captured by trees, plants, animals, and then buried with them. “What we have been doing for 150 years is digging it up and putting it back into the atmosphere,” confirms Martin Siegert, professor of geoscience at Imperial College London."
And, the trend is up for the concentration of the CO2 in the atmosphere, starting to get exponential.
I am no expert, but have done research on the subject and have no choice to go with the consensus of experts, even if there exists a minority of other experts that do not believe this stuff. |
