Global Change Biology- blackwellpublishing.com There are free articles that dive into the numbers-- some I feel are assumptions built on assumptions-- example: ================================================== Ocean uptake is driven by the dissolution of atmospheric CO2 in surface waters and the subsequent mixing between the surface and the deep ocean. Equilibrating the surface ocean with atmospheric CO2 takes roughly one year, while mixing the entire ocean takes several centuries. On the time scale of roughly one century, over which most of the emissions have occurred, the oceans have absorbed about 124 PgC, or 26% of the total emissions. This estimate is based on an uptake of 107 PgC before 1990, from geochemical observations (Gruber, 1998; Sabine et al., 1999, 2002), and a further 17 PgC for the 1990s, based on atmospheric CO2 and O2 measurements (IPCC: Prentice et al., 2001; based on Langenfelds et al., 1999; Manning, 2001). The remaining fraction (34%) of total emissions unaccounted for by the atmospheric increase and ocean uptake has been absorbed by the land biosphere through a combination of processes whose relative importance is still not firmly established: growth of replacement vegetation on devegetated land, land management practices (such as fire suppression leading to woody encroachment and agricultural and forest management, e.g. Spiecker et al., 1996; Houghton et al., 1999; Archer et al., 2001), fertilizing effects of elevated CO2 and nitrogen deposition (e.g. Lloyd, 1999; Holland et al., 1997; McGuire et al., 2001), and impacts of climate change such as an increase of growing season length in high latitudes (Myneni et al., 1997). To calculate the effect of a complete land restoration on the same time scale, three hypotheses are considered: more: blackwell-synergy.com ======================================================= and from this you read articles from established sites that are more interesting:(where I first got the link to global change) "New trees cancel out air pollution cuts" Message 20858768 me thinks politics in science is just as bad as politics in religion as politics are in your school district-- don't let the facts get in the way of your view or agenda- too bad we aren't equipped with a BS monitor stuck to our foreheads.
