"Global Efforts On Ozone Help Reverse Southern Jet Stream Damage"

"Jet stream appears to have stopped moving south and may be moving back towards normal"

"International cooperation on ozone-depleting chemicals is helping to return the southern jet stream to a normal state after decades of human-caused disruption, a study shows.

Scientists say the findings prove there is the capacity to heal some damaged climate systems if governments act promptly and in coordination to deal with the causes.

The southern jet stream is a powerful wind that shapes weather patterns and ocean currents in the southern hemisphere, particularly in the summer.

Up until about 2000 it had been shifting from its usual course and moving southwards towards the Antarctic at a rate of one degree of latitude each decade, affecting storm tracks and rainfall over South America, east Africa and Australia."
