I’ve posted articles in the past linking the clean air legislation in the west with more sunshine and therefore more warming. Here is a paper arguing the opposite: the lack of clean air in China is cooling the globe.
China is responsible for just 10 per cent of man-made global warming, despite emitting more than one quarter of the world’s greenhouse gases, a new study claims.
The study found sulphate and nitrate aerosols emitted by burning fossil fuels had a cooling effect that offset much of the warming caused by greenhouse gas emissions of carbon dioxide, methane and black carbon.
As a result, while China’s consumption of fossil fuels and its carbon emissions had increased significantly over the past decades, a corresponding increase in aerosol emissions meant its contribution to man-made climate change had remained largely unchanged since the pre-industrial period.
The study was led by Professor Li Bengang at Peking University and published in Nature.
