yes, the cartoon which purported to be sourced from the 2007 eia report, (which did NOT make the claims stated), but you retort with "wiki-wisdom" which is once again WRONG!
Wikipedia's assertion for 2010 (from your "supporting link", which was not about 2007 at all):
US: 4,433.057 million metric tonnes
World: 31,350.455 million metric tonnes
the EIA's assertion for 2010:
US: 5,636.739 million metric tonnes
World: 31,502.374 million metric tonnes
why the discrepancy? only the wikipedos know for sure.
the wikipedos claim to have gotten their data from the EIA in the first place, so the mystery deepens,
