Deserts turn leafy in global greenhouse

MAN-MADE pollution, blamed for changing the Earth’s climate, may have an upside for the planet, scientists believe.

Research has found that trees and plants in some of the world’s most arid regions are thriving, seemingly as a result of greenhouse gas emissions.
After studying satellite photographs taken over 30 years, researchers found green cover had increased in various regions from the Middle East to Australia and also in dry parts of North America.
They believe the growth has been encouraged by the same increase in carbon dioxide that is widely blamed for a rise in global temperatures.

Randall Donohue, a scientist at the Commonwealth Scientific and Industrial Research Organisation (CSIRO) in Canberra, Australia’s capital, and a senior member of the research team, said: “Even if nothing else in the climate changes as global CO2 levels rise, we will still see significant environmental changes because of the CO2 fertilisation
