Previous “world-avoided” experiments have shown that, without the Montreal Protocol, ozone levels would be depleted globally by the mid-twentieth century.

Protecting the ozone layer also protects Earth’s vegetation and has prevented the planet from an additional 0.85 degrees Celsius of warming, according to new research from Lancaster University, NASA, and others. This new study in Nature demonstrates that by protecting the ozone layer, which blocks harmful ultraviolet (UV) radiation, the Montreal Protocol regulating ozone-depleting substances also protects plants – and their ability to pull carbon from the atmosphere. The impact from plants has not been accounted for in previous climate change research.
