Climate change may be faster than expected http://apocadocs.com/s.pl?1255479349
A team of U.S. scientists has, for the first time, successfully incorporated the nitrogen cycle into global climate change simulations.... "We've shown that if all of the global modeling groups were to include some kind of nutrient dynamics, the range of model predictions would shrink because of the constraining effects of the carbon nutrient limitations, even though it's a more complex model," Oak Ridge scientist Peter Thornton said.
By taking the natural demand for nutrients into account, the authors demonstrated the stimulation of plant growth during the coming century might be two to three times smaller than previously predicted. Since less growth implies less carbon dioxide absorbed by vegetation, the CO2 concentrations in the atmosphere are expected to increase.
