Africa's savannahs may change into forests before the turn of the century due to excess CO2

Daily Mail: A study suggests that some of Africa's savannahs - large areas sparse vegetation other than grass - may become forests by the end of the century. Research from The Biodiversity and Climate Research Centre and the Goethe University Frankfurt suggests that a build-up of carbon dioxide in the soil will force an increase of tree cover throughout Africa.
