New research shows iodine in Earth’s early atmosphere delayed the ozone layer’s stabilization, affecting life evolution.

Ozone depletion over the Arctic has been much less pronounced than over the Antarctic Scientists have detected an unexpected rise in atmospheric levels of CFC-11, a chlorofluorocarbon (CFC ...

Previously, many believed that primary chlorofluorocarbons (CFCs) were responsible for the depletion of ozone in Earth’s atmosphere. The discovery of the Antarctic ozone hole did prove that CFCs ...

Ravishankara and colleagues 3 quantify the ozone depletion potential of nitrous oxide — essentially a measure of the amount of ozone destroyed by nitrous oxide, compared with that destroyed by ...

ozone-destroying chemical. CFC-11 was primarily used for home insulation but global production was due to be phased out in 2010. But scientists have seen a big slowdown in the rate of depletion ...
