The world’s population is rising and with it are food demands. Policymakers are targeting Africa’s wet savannas as expendable areas easily converted into cropland. A study out from Princeton University finds that such a conversion to farmland would come at a high environmental cost.
Scientists at the US Department of Energy’s Lawrence Berkeley National Laboratory demonstrated the first direct observation of increased radiative forcing due to increased carbon dioxide levels in the atmosphere. This study, published in Nature , is the first to provide direct observational evidence linking rising carbon dioxide concentrations to the greenhouse effect.
