Coal-burning China's rapid growth may have HALTED global warming - 5th July 2011

China's rapid industrial expansion may have halted global warming for much of the last decade, climate scientists claimed.

They said sulphur pollution from China’s coal-fired power stations helped to keep world temperatures stable despite soaring greenhouse gas emissions.

Burning coal releases carbon dioxide which traps heat from the Sun, raising temperatures. But it also emits particles of sulphur that help block the Sun’s rays and cool the Earth.

‘During the Chinese economic expansion there was a huge increase in sulphur emissions,’ Dr Robert Kaufmann, of Boston University, told the journal Proceedings of the National Academy of Sciences.

But it is thought temperatures will rise again now China is tackling air pollution by installing equipment to scrub out sulphur particles. Read More
