UN report: Ozone layer on track to fully recover within four decades
The ozone layer in the upper atmosphere that shields life on Earth from deadly solar radiation is on track to recover within four decades, according to a major scientific report released Monday.
The ozone layer is expected to recover to 1980 values by around 2066 over the Antarctic, 2045 over the Arctic, and 2040 for the rest of the world.
According to the assessment report from a UN-backed panel of experts, the UNEP said that nearly 99 percent of banned ozone-depleting substances had been phased out, amid a boost to planetary health and climate resilience.
Signed in 1987, Montreal Protocol is an international treaty banning chemicals that destroy this naturally occurring layer of molecules, especially over the polar regions. And the treaty is working as intended, more than 200 authors and reviewers from US, European and UN agencies found.
