[QUOTE="eclipsenow, post: 77649886, member: 274355"] As others have said - yes - and the paleoclimate proxies show our CO2 is much faster and greater than natural emissions for the past 10's of millions of years. There was a period about 55 million years ago where nature beat even what we've done today through increased volcanism releasing more CO2 - but it took tens of thousands of years to do it! It was a much slower rate of release. Also, the different isotopes of CO2 in the atmosphere show it's us.
