Well considering CO2 is a TRACE gas that only makes up 0.04% of the atmosphere, and we have an atmosphere that is 5,000 trillion metric tons which might as well be infinity as far as man is concerned, I wonder if we contribute anything at all considering the plants that absolutely dominate this planet. North America, South America all you see is green green and then you have the ocean with it's plants, algae, phytoplankton and macrophytes like seaweed that suck in CO2 and release O2. We'd have to overcome the CO2 intake of allllll that, plants on land and the sea, and what is left over is what we would contribute to that 0.04%. Call me naive but I doubt it's much. Methane is an even more ridiculously small number at 0.00017% and even IF we could raise the CO2 levels to any significant amount that would raise the temperature and create a greenhouse effect, what is the worst that will happen? We get more plants? More rain from the greenhouse effect? So in other words the water shortage would be solved? The ice caps will melt and sink the liberal sewer holes of New York city, San Fran and Kennedy lair "Bahston"? Yeah? And? What's the problem? I see only positive results from Gorebull warming.
Don’t leave out the phytoplankton in the photic zone of all the bodies of water.
They are a tremendous ‘carbon sink’
