- Abstract
Replyingto L. M. Polvani et al. I Nature Commun i I ications i https://doi.org/10.1038/s41467-023-37134-3 (2023) Long-term declines in the thickness of Earth's protective ozone layer have been caused by the decomposition products of organic chlorine and bromine compounds such as chlorofluorocarbons and halons that have been phased out by the Montreal Protocol and its amendments and adjustments. Therefore, we suggest the statement by P22 that "Arctic ozone column in these models are consistent with the observed ozone column over the period 1979-2021" is misleading. Here, we interpret their statement to mean that increased levels of CO SB 2 sb do not amplify the impact of the ODSs on ozone, since we all agree ODSs are the cause of chemical loss of Arctic ozone. 10.1002/jgrd.50316 14 Eyring V.
