World 'needs radical cuts' on CO2
By Tanya Syed BBC News
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.
But they add that it is still possible to arrest and manage climate change with renewable technologies and more efficient ways of living.
"Sealing the deal to save the global climate will require mass public support and worldwide political will to shift to renewable energy, new ways of living, and a human scale that matches the atmosphere's limits," said Robert Engelman, vice president for programmes at the Worldwatch Institute.
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."
