I know.
I’m being contrarian and giving the other side time to take my bait so I can then draw a picture of what desertification looks like
Must have been a healthy amount of green plants to feed the critter,...estimated to stand 65 feet tall and 130 feet long and packed the weight of 14 elephants.
I haven't seen too many publications about the CO2 problem lately, but a few years ago, I saw an article estimating that life on earth will go extinct in a few hundred million to a billion years because of the continuing decline of CO2 in the atmosphere. The mechanisms by which CO2 is sequestered in non-gaseous form are still not fully understood. I believe that I put a reference to this work in my profile.
Of course, atmospheric CO2 is the source of all carbon used by living things to increase their biomass. The only way to see a real decrease in CO2 will be to decrease the biomass. An analogy would be a sealed container of water. The airspace in the container at a given temperature will always have a certain level of humidity, which will remain as long as liquid water is in the container. The only way to decrease the humidity would be to remove the liquid water. In the case of carbon, the biomass is equivalent to the water, and the CO2 is equivalent to the vapor.
A big concern that I have right now is that these kooks will get their way and start to filter out and sequester atmospheric CO2. At some concentration, plants will no longer be able to filter CO2 from the air--the specific concentration will depend on species, so die-offs will occur in a species-specific manner. Since the decaying plants return CO2 to the atmosphere, the concentration of CO2 will not change much, but will hover around the limit of what that species can extract from the air. Decreased plant biomass also causes decreased everything else biomass. As the more susceptible species die off, there will be less and less biomass--still with little change on atmospheric CO2. By the time the change in CO2 concentration becomes significant, the biosphere will be gravely damaged.
I have seen commercials suggesting that limiting CO2 emissions will increase the quality of air for breathing. These commercials are factually wrong--CO2 content does not affect the ability to breathe. People regulate the amount of CO2 in their blood--which is far more concentrated than in the atmosphere--by changing the rate of breathing, and a change of a few tens of PPMs will not significantly affect that dynamic.
Sorry for being so wordy here. CO2 hysteria is a pet peeve of mine. It is clear that the hysteria is being drummed up so as to decrease our resistance to totalitarianism, and, unfortunately, too many people are falling for it.
