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?
