See "Global Climate Change", by R.A. Houghton and G.M. Woodwell, Scientific American, 260:4 p36-44 April 1989. The authors expect warming trends, "rapid now, [to] become even more rapid as a result of the warming itself, and ... [to] continue into the indefinite future unless we take deliberate steps to slow or stop it." They call for "a 50 percent reduction in the global consumption of fossil fuels, a halting of deforestation, a massive program of reforestation." I have a few questions for the more knowledgeable: 1. To what extent do algae and other ocean plant-life contribute to the total photosynthesis on the earth? 2. The oceans "release about 100 billion tons [of carbon] and absorb 104" annually through physicochemical processes(Houghton et al, p38.) CO2 dissolves more readily in cold water than in warm water. As the surface water heats up, the oceans should not be able to absorb as much CO2. At some point shouldn't this effect cause a net release of CO2? Thanks, -- Paul Shields, shields@yunccn.UUCP

According to "Plant Physiology" by Salisbury and Ross, approximately one third of the photosynthetic primary production occurs in the oceans. This corresponds to an estimated 55.0 dosvsunix filesystem helpnotes mbox postrules pwadvice rules scratch secretmail sitenotes synopsis tnlediting tnllogin usenetfacts usenetslang usingunix 10^9 metric tons of organic matter with an empirical formula close to CH20, so represents about 22 billion tons of carbon fixed in the oceans due to photosynthesis. .
