Humans only add 3% of the CO2 nature 97%

Neo, this is amazing. You obviously don't WANT to understand. Where do you think all that extra CO2 went? People put 100% of their CO2 into the atmosphere. Only a portion of it is still there. Where did the rest go? How much per year disappeared? It was a LOT of it. < plants will not in fact suck out the human increased CO2. Which is why I'm belaboring you. Plants only sequester carbon if new forests are growing, or areas which were not filled with plant life are filled with new plant life. Once the forests reach maturity, or the new areas are filled with plants, they again become carbon neutral. > Plants are gobbling CO2 all day every day. It's what they do. They don't stop and watch TV or go to the boozer. Sometimes, if they are really dry [say a cactus in a desert] they might not take in much, but they still take in a little bit. If they are right out of water, they'll rest on the oars too. But overall, they are on the job, going flat out. As proven by how quickly they suck the CO2 levels down during the big northern growth period each year. But it doesn't all come back over the following 6 months as leaves rot and animals eat plants like piggies [breathing out the results as CO2]. Animals have bones for example and marine animals sink to the bottom of the ocean. The ocean floor has kilometres of sediment which contains carbon as carbonates and other carbon compounds. That is the essential point which you should try to understand and why Gaia is NOT in balance, never has been and is a suicidal maniac intent on turning Earth into an icy wasteland [or, as I said, Gaia has figured out that the sun is going to get hotter and is getting ready by making Earth a lot colder so that when the sun gets hotter, we'll be ready]. Peat, coal, swamps, radiolarian ooze - carbon is constantly being stripped out of the atmosphere. It isn't just an endless cycle. Where do you think the vast coal deposits came from? What do you think the Dolomite mountains, White Cliffs of Dover and Nullarbor Plain, are made of? CO2 is sucked out quickly from the atmosphere when there's a big surplus of it, which there is thanks to people putting it there. We know just how quickly because we know how much CO2 people have put into the atmosphere since 1990. We know how much CO2 was in the atmosphere then and now. So, simple arithmetic is sufficient to calculate the average rate at which CO2 has been removed. But bear in mind that in 1990, the pressure reducing CO2 was a LOT less than now with much higher levels of CO2. The rate of absorption from the atmosphere is a function of the concentration of CO2. The higher the concentration, the faster it's removed. Certainly within the ranges we are talking about - let's not worry about 2000 ppm levels for now when things might be different. Mqurice
