No evidence of worsening Arctic springtime ozone losses over the 21st century Nature Communications

of VDG, that “conditions favourable for large, seasonal loss of Arctic column ozone could persist or even worsen until the end of this century, if futureabundances of GHGs continue to steeply rise ”,w h i c hi sb a s e do na n proxy index of future loss, not the actual model output of ozone loss,appears to contradict a large body of evidence from chemistry-climate models, which have consistently shown how rising GHG will lead to higher ozone levels, not the other way. Finally, regarding the narrow question of seasonal chemical ozone
