Islam News – A U.N.-backed report found that the ozone layer could be restored within a few decades, now that China has begun successfully cracking down on rogue emissions of a banned chemical.

That’s big news: In 2018, scientists revealed that global emissions of CFC-11, a chemical most likely used to make foam insulation, had increased since 2012. Investigations by The Times and others strongly suggested that small factories in Eastern China disregarding the global ban were the source.

In 2018, the head of the U.N. Environment Program said the rogue emissions, if they continued, could delay ozone recovery by a decade. But now, scientists said that ozone levels between the polar regions should reach pre-1980 levels by 2040. Ozone holes should also recover.

Ozone: The protective layer in the upper atmosphere blocks ultraviolet radiation from the sun, which can cause skin cancer.

Context: The Montreal Protocol, the treaty negotiated in the 1980s to phase out the use of such chemicals, is generally considered to be the most effective global environmental pact ever enacted.
