Climate change to favor trees over grasses in Africa

Mongabay: As the world warms, scientists are working rapidly to understand how ecosystems will change, including which species will benefit and which will falter. A new study in Nature finds that elevated CO2 concentrations should favor trees and woody plants over savannah and grasslands in Africa. While the study's climate change models predict abrupt shifts at the local level, these changes will seem to occur smoothly when averaged across a continent and viewed over time. The explanation for this vegetation...
