A new international study published in the journal Communications Earth & Environment<\/em> shows that the sharp decline in China\u2019s fine particulate \u2013 or aerosol<\/em> \u2013 emissions is the most important single factor behind the acceleration of global warming since 2010. Aerosols have previously cooled the climate, but their reduction has now made the warming effect of greenhouse gases more clearly visible. The Finnish Meteorological Institute contributed to the research through comprehensive climate simulations. According to the results, the reduction in China\u2019s aerosol emissions alone has increased global average temperatures by approximately 0.07\u202f\u00b0C since 2010. The induced  warming is evident across the entire Northern Hemisphere.<\/p>\n\n\n\n

While improving air quality saves lives, the study highlights the urgent need to reduce greenhouse gas emissions. The study is part of the Finnish Meteorological Institute\u2019s long-standing international collaboration on the climate effects of aerosols and part of the ACCC flagship<\/strong> (Atmosphere and Climate Competence Center).
