A modeling study published in the journal Nature last year describes a recent, rapid shift in extensive areas of African grassland and savanna to more densely vegetated, wooded states, a trend that is expected to accelerate in coming decades as atmospheric concentrations of CO2 rise.

Already there are signs that open-country animals like the cheetah are suffering as savanna becomes more wooded. This trend is not confined to Africa.

An Australian study released last month, which relied in part on satellite data, concludes that foliage cover in warm, arid areas worldwide has increased by about 11 percent in the last three decades due to higher CO2 levels.
