Arid Regions Green As CO2 Levels Rise

A new scientific paper reports on the greening of semi-arid regions since 1982, as a result of the “carbon fertilisation” effect.  Plants grow by photosynthesising atmospheric carbon dioxide and turning it into hydrocarbons to feed on.

Australian scientist Randall Donohue and his team predicted that rising atmospheric carbon dioxide levels, the result of increased fossil fuel burning worldwide, would increase the growth of plants in semi-arid areas.
