China’s success in cleaning up air pollution may have accelerated global warming: Study
EAST ASIA, JUL 14 – A 75% cut in East Asian sulphur dioxide emissions since 2013 has reduced cooling aerosols, contributing to recent global warming acceleration, researchers say.
- A study published on 14 July in Communications Earth and Environment found that East Asia's air pollution cleanup has accelerated global warming.
- This acceleration occurred after a substantial 75% decline in sulfur dioxide pollutants in East Asia beginning in approximately 2013, driven largely by Chinese regulations aimed at curbing aerosol pollution.
- The cleanup caused clouds to darken and reflect less sunlight, reducing cooling from aerosols and revealing more greenhouse gas warming since 2001.
- Peter Cox noted that the majority of the global temperature rise since 2001 can be attributed to decreases in SO2 emissions instead of increases in CO2 levels, while Laura Wilcox highlighted that this recent rise in warming is expected to be temporary.
- The findings suggest that while global warming will continue for decades, faster recent warming partly reflects a temporary effect from reducing air pollution in East Asia.

Global warming has accelerated since 2010, leading to a series of record-breaking warm years. A recent study suggests that one of the main reasons for the acceleration is the successful efforts of East Asian countries, especially China, to improve their air quality, which has led to the disappearance of a number of aerosol particles from the atmosphere that have cooled the planet.
Was East Asian air cleanup behind recent global warming showtime?
Global warming has picked up pace since around 2010, leading to the recent string of record warm years. Why this is happening is still unclear, and among the biggest questions in climate science today. Our new study reveals that reductions in air pollution – particularly in China and elsewhere in East Asia – are a […] The post Was East Asian air cleanup behind recent global warming showtime? appeared first on Asia Times.
Because the people were finally to breathe cleaner air, the power plants in China were rapidly effluent. This gets bad to the climate, the warming accelerates.
China's success in cleaning up air pollution may have accelerated global warming: Study
(The Hill) – Efforts to clean up air pollution in China and across East Asia may have inadvertently contributed to a spike in global warming, a new study has found. The decline in aerosol emissions — which can cool the planet by absorbing sunlight — have added about 0.05 degrees Celsius in warming per decade since 2010, according to the study, published on Monday in Communications Earth & Environment. At that time, China began implementing aggr…
