‘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
