Atmosphere Needs Radical Reduction Of CO2

"More carbon dioxide needs to be absorbed than emitted by 2050 in order to prevent catastrophic climate change.

That is the conclusion of a report by the Worldwatch Institute which urges bigger cuts in greenhouse emissions.

The authors say that even a rise in temperatures of 2 degrees C poses unacceptable risks to natural systems.

Commenting on the report, Ian Lowe, president of the Australian Conservation Foundation, said: "It is a persuasive call to action. Unless we take early concerted action, the impacts of climate change will overwhelm our capacity to adapt.""
