A scientific paper, published in Nature, indicates a rare environmental success. The ozone layer is continuing to heal and has the potential to fully recover, say scientists. Experts confirm that changes in the jet stream and air circulation patterns are evidences of the recovery of the Earth’s protective ozone layer. These changes are due to the shrinking ozone hole following the implementation of the Montreal Protocol, that banned the use of chlorofluorocarbons in 1987, says the study and that indicates the success of the protocol. The study serves as an example of the reversal of environmental damage and shows that orchestrated global action can make a difference.
