Summary/Abstract
Using climate model simulations, the paper quantifies how anthropogenic influences, especially increased greenhouse gas emissions, have altered atmospheric patterns to increase the likelihood of severe haze events in eastern China. The research finds that the anthropogenic effect has increased the probability of conducive atmospheric conditions by at least 45% in January 2013 and 27% in December 2015. The findings underscore the need for stringent emission reduction measures and adjustments in air quality management to mitigate the impacts of such haze under ongoing climate change.
