Amid the flood of bad news of the past few days, behold, we have good news to share! A survey showed that the ozone layer is recovering and regenerating the circulation of winds throughout the planet, especially in the Southern Hemisphere, and the restoration appears to be associated with the measures agreed and put into action since the signing of the Montreal Protocol, in 1987.
Just so you can better understand the importance of this result, you may have heard of drafts known as “jet streams”, right? They circulate at high altitudes and speed between the troposphere and the stratosphere and flow towards the poles. Because, due to the rarefaction of the ozone layer, these currents had begun to circulate further south than normal in our hemisphere, thereby affecting rain patterns – and possibly even those of ocean currents, interfering, for their part. time, in the weather.
What the survey showed was that, just over 1 decade after the Montreal Protocol came into force, the displacement of jet streams stopped – and even reversed at some points – showing that the joint effort and global commitment to stopping the manufacture and emission of substances harmful to the ozone layer yielded excellent fruits.
