[Phys-l] N. America's sink > a source of CO2. Was: [tap-l] Another Inconvenient Truth?



This from tap-l

bc, thinks this may interest PHYS-Lers
------------------
Some past studies

e.g. S. Fan, et al., "A Large Terrestrial Carbon Sink in North America Implied by Atmospheric and Oceanic Carbon Dioxide Data and Models", Science, vol. 282, 16 October 1998

indicate that North America is a net sink for atmospheric carbon dioxide; that is, North America takes more CO2 out of the atmosphere than it puts in. This is supported by data indicating that atmospheric carbon dioxide levels are higher over the North Pacific - before traversing the continent - than over the Atlantic.

Anyone know anything about this? Has it been disproved? Are there more recent studies pertaining to this phenomenon?
