Research led by the Open University’s Dr Vincent Gauci suggests that sulphur-based acid rain from atmospheric pollution could cut the methane emissions associated with cultivating rice by almost a quarter. Tonne for tonne, methane is more than 20 times more potent than carbon dioxide in terms of global warming. Dr Gauci’s findings suggest …
