Carbon dioxide (CO2) increases tree cover throughout Africa…

Steven I. Higgins and Simon Scheiter (2012). Atmospheric CO2 forces abrupt vegetation shifts locally, but not global. Nature Climate Change, DOI: 10.1038/nature11238

From CORDIS:

“Writing in the journal Nature, Steven Higgins from the Goethe University Frankfurt and Simon Scheiter from the Biodiversity and Climate Research Centre (BiK-F) in Frankfurt suggest that fertilisation by atmospheric carbon dioxide (CO2) is leading to major increases in tree cover throughout Africa.
Grasses and trees differ fundamentally in their response to temperature, CO2 supply and fire, and continually struggle for dominance in savannahs.
Previously, these shifts in dominance have taken place over long periods of time, but the current wave of atmospheric changes has sped up rates of change.”

“Once a critical threshold of CO2 concentration is exceeded, savannahs become less grassy and more forest-like. However, each savannah has its own critical threshold which means that each savannah will make the switch at different times. This helps reduce the risk of a simultaneous and dramatic change emanating from the savannahs.”
