- We’ve gone up from 300-400 PPM in the last 200 years -- however, half of that happened before man contributed much to the CO2 cycle at all (beginning around 1950 when man first crossed the 1 gigaton/year level), and much of the rest was due to the Oceans releasing CO2.
- Whether more is being captured than lost (and how much) is still in continuous debate, We aren't sure if there are positive or negative feedbacks. All we know is that the IPCC climate models are broken (we've fallen off the bottom of projections, and they failed and their predictions): the debate is over how wrong they are.
- People get confused here. Why isn't CO2 causes warming proven? They think CO2 causing our warming is a fact. Well, CO2 does catch wavelengths of light, and that's "warming", so that part is known and is what most scientists are asked about ("Q: does CO2 cause warming? A: Yes"). But there are many other things at play that cause cooling. Some other factors are:
- As the climate warms, we release more water vapor: which becomes clouds, which reflect light (albedo effect), resulting in cooling, and it causes more rain (which scrubs more CO2 out of the air)
- CO2 stimulates more plants, which absorb more CO2 (especially algae's), which sequesters CO2
- CO2 converts light to heat (in the upper atmosphere) -- but if it didn't, most would get down into the lower/denser atmosphere where it's captured by water vapor and the the ground anyways. Even the biggest alarmist admit that a doubling of CO2 is at MOST worth 1-3° of warming (not very much), and that's based on the flawed simplification that is the IPCC models.
