International ozone treaty stops changes in Southern Hemisphere winds

The video discusses the phenomenon of Antarctica's ozone hole and its impact on atmospheric circulation, including the shift of the mid-latitude jet stream. The Montreal Protocol, signed in 1987, aimed to phase out CFCs, which has helped halt the jet stream's southward drift. Researchers from the University of Colorado Boulder suggest that climate warming is pushing the jet stream south, while ozone layer recovery is counteracting this shift. Ozone depletion is also linked to the expansion of the southern hemisphere's tropical dry region, affecting rainfall in South America, East Africa, and Australia.
