How the Montreal Protocol saved the Earth from a nightmare climate scenario

The video discusses the significant impact of the 1987 Montreal Protocol in preventing the collapse of the ozone layer and mitigating climate change. Without the protocol, increased CFCs would have led to severe environmental damage and a substantial rise in global temperatures. The study highlights that the protocol has prevented a 2.5°C increase in global warming. The UN's recent climate report shows progress in combating climate change, projecting lower temperature increases than previously expected.
