Where did you get these numbers from? I've seen a lot of stats from pro and con man made global warming groups and none have ever been as far fetched as this... 22gigatons by humans? The only time I've seen a number like this is when they haven't accounted for how much has been taken back by nature! Even then, your number seems to have a factor of 2 higher than anything I've seen!

As far as I can tell you got these numbers from Yahoo answers or Wikianswers. Not from a sound scietific report!
