Chinese researchers have discovered that rising methane emissions may unexpectedly benefit the recovery of the ozone layer, offering new insights into climate governance.
The study, led by a team from Beijing Normal University, has been published in the journal Advances in Atmospheric Sciences.
The ozone layer serves as Earth's protective barrier against harmful ultraviolet radiation. Although global initiatives have successfully reduced ozone-depleting substances, the future restoration of the ozone layer is now facing new challenges due to climate change and human activities.
The research underscores methane's complex role in ozone recovery. Methane is a powerful greenhouse gas that contributes to global warming, yet it also engages in intricate chemical interactions within the atmosphere that may facilitate the recovery of the stratospheric ozone layer, noted Xie Fei, a professor at Beijing Normal University.
"Just as ozone can be harmful at ground level but beneficial in the stratosphere, methane and other ozone precursors exhibit similar dual characteristics," Xie stated.
"Understanding these dual effects is critical for predicting future ozone recovery and its implications for climate," he added.
The research team carried out experiments to investigate the influence of methane, carbon dioxide, and sea surface temperatures on stratospheric ozone under the Representative Concentration Pathway (RCP) 8.5 scenario for 2050. This scenario represents a future climate trajectory characterized by high greenhouse gas emissions and inadequate climate mitigation efforts, resulting in substantial global warming by the century's end.
The findings indicated that increased methane emissions could significantly enhance ozone recovery in both the Arctic and Antarctic regions.
"Our ultimate goal is to provide a comprehensive understanding of ozone recovery pathways and their broader implications," Xie remarked, noting the intention to improve their models to include additional factors that affect ozone recovery.
"This will help policymakers and scientists make better decisions to address both ozone layer restoration and climate change," he concluded.
