英国布里斯托大学Western Luke M.团队取得一项新突破。他们的最新研究报道了来自氟氯烃的辐射作用力和等价有效氯的降低。相关论文于2024年6月11日发表在《自然—气候变化》杂志上。
据了解，《蒙特利尔议定书》及其后续修正案通过控制生产/消费，成功地遏制了臭氧消耗物质和强效温室气体的排放。
研究人员表示，自2021年以来，来自氟氯烃的辐射作用力和等价有效氯已从61.75mW m−2和321.69ppt下降，且比预期时间提前了5年。这一重要里程碑表明了《议定书》在减缓气候变化和平流层臭氧层损失方面的益处。

Abstract: The Montreal Protocol and its successive amendments have been successful in curbing emissions of ozone-depleting substances and potent greenhouse gases via production/consumption controls. Here we show that the radiative forcing and equivalent effective chlorine from hydrochlorofluorocarbons has decreased from 61.75 mW m−2 and 321.69 ppt, respectively, since 2021, 5 years before the most recent projected decrease. This important milestone demonstrates the benefits of the Protocol for mitigating climate change and stratospheric ozone layer loss. Hydrochlorofluorocarbons are important ozone-depleting substances. Here the authors show that the radiative forcing and equivalent effective chlorine from hydrochlorofluorocarbons has decreased in recent years, 5 years earlier than expected.
