The recovery of Earth's ozone layer is back on track, according to a new report from a panel of UN-backed scientists.
The report found that recent rogue emissions of CFC-11, an ozone-destroying chemical that was primarily being released from, have significantly declined since 2018, putting the ozone layer on course to recover within four decades.
Interactions between ozone and CFCs and halocarbons occur in the extreme cold of the Arctic and Antarctic stratosphere, which is why ozone "holes," or a thinner layer of ozone, first formed over Antarctica.
