Russian scientists have discovered that volcanic particles can help cool the Earth, a leading environmental scientist said yesterday.

The world's temperature can drop 0.5 to 1 C a year if 1 million tons of volcanic particles are sprinkled across the globe from 10 to 14 km in the sky, said Yuri Israel, deputy head of the UN Inter-governmental Panel on Climate Change (IPCC), which won this year's Nobel Peace Prize with former US vice-president Al Gore.

"Our experiments have shown it's effective, and actually it's more effective than some methods stipulated in the Kyoto Protocol to mitigate global warming," Israel said during a Moscow-Beijing video-conference on climate change. The conference was part of an exchange program between Russia and China.
