Jon notes that the response by alarmists to these storms would be “at least America gets hit by something caused by the global warming we “created”.” Of course this is predicated on our high gross emissions of carbon dioxide. An interesting article from Science back in 1998 suggests that while our emissions might be high (although not on a per unit of economic output basis) our net contribution to global carbon dioxide levels may actually be negative. An article by S. Fan, M. Gloor, et. al. suggests that North America is a carbon sink. This means that trees, vegetation , etc. may be using more CO2 than is being emitted. In case anyone wants to go to the library and look it up, the title of the article is “A Large Terrestrial Carbon Sink in North America Implied by Atmospheric and Oceanic Carbon Dioxide Data and Models,” Vol. 282, October 16, 1998.
