Saving ozone layer reduced climate change effects

The video discusses the Montreal Protocol, an international agreement signed in 1987 to halt the production and import of ozone-depleting chemicals like chlorofluorocarbons (CFCs). It highlights the protocol's success in allowing the ozone layer to recover and its significant role in slowing climate change by reducing temperature rise. The study estimates that the protocol has helped avoid a temperature increase of 0.5 to 1 degree Celsius in some areas and 3 to 4 degrees Celsius in the Arctic. By 2050, the planet is expected to be at least 1 degree Celsius cooler due to the protocol. Additionally, the Arctic summer sea ice extent is 25% higher, and Greenland's ice sheet is melting slower than it would have without the agreement.
