Research reveals decade of global warming from China's coal power stations has partly been offset by 'cooling' effect of sulphur pollutionThe huge increase in coal-fired power stations in China has masked the impact of global warming in the last decade because of the cooling effect of their sulphur emissions, new research has revealed. But scientists warn that rapid warming is likely to resume when the short-lived sulphur pollution – which also causes acid rain – is cleaned up and the full heating effect of long-lived carbon dioxide is felt.The last decade was the hottest on record and the 10 warmest years have all occurred since 1998. But within that period, global surface temperatures did not show a rising trend, leading some to question whether climate change had stopped. The new study shows that while greenhouse gas emissions continued to rise, their warming effect on the climate was offset by the...
