Changes to land cover may enhance global warming in Amazon, reduce it in midlatitudes New simulations of 21st-century climate show that human-produced changes in land cover could produce additional warming in the Amazon region comparable to that caused by greenhouse gases, while counteracting greenhouse warming by 25% to 50% in some midlatitude areas. The simulations from the National Center for Atmospheric Research (NCAR) show the importance of including land cover in computer-model depictions of global change. The results will be published in the December 9 issue of Science.
