A 3-degree rise would threaten the ozone layer

We live in a world where the continuous increase in temperatures is causing many problems within the globe, such as thawing and the consequent rise in sea level, increasingly intense droughts, more devastating cyclones, but we often forget about the layer of ozone.

This layer, which extends from approximately 15km to 50km in altitude, is very important to preserve health. Now a study has also revealed that a 3 degree warming could seriously threaten it.

The disappearance of the ozone layer, or even its reduction, could increase the number of cancer cases. This, which at first might seem distant, might not be so far. The increase in temperatures is a real fact all over the planet: we have been more than 300 consecutive months in which values ​​are registered above the usual.

With pollution, deforestation, as well as with the use of toxic products for the environment, human beings are putting themselves and all other forms of life on this planet in danger.

According to the study, which has been published in the journal Nature Communications, it is very important that global measures are taken to regulate methane production, which is a serious environmental problem in Europe.

The study authors, including Audrey Fortems-Cheiney of the French institute Institut Pierre Simon Laplace, used a chemical transport model to examine what would happen to ozone if temperatures 2 or 3 degrees higher were reached in different scenarios with different mitigating factors.

Thus, they were able to observe that in a scenario without mitigating greenhouse gas emissions, with a warming of 3ºC between 2040 and 2069, ozone levels were 8% higher. If it becomes a reality, the reductions achieved with the implementation of ozone emissions regulations would be exceeded; Or put another way: the hole in the ozone layer, located about 15km from Antarctica, could be made bigger.
