The Kyoto Protocol, created in 1997 to fight global warming by cutting greenhouse gas emissions like CO2 and methane, has had limited success. Only some countries reduced emissions while global CO2 levels increased by 60%. The protocol acted as a brake on rising emissions but didn't stop overall growth. This happened despite solid scientific evidence on global warming's dangers and connections to specific gases. Unlike the Montreal Protocol that's helping the ozone layer recover, Kyoto faced challenges. Its impact might be weak, but it did contribute to global efforts against climate change.
