In 1987, with the rupture of the ozone layer on Antarctica and the growth of this tear-out dimension, world countries agreed with the name of chlorofluorocarbons (CFCs) by a common decision. an agreement has been reached on the prohibition or supervision of the use of the various chemicals supplied. Over time, it began to shrink with the decrease in the use of these chemicals, and everything seemed to be in order.
However, starting from 2013, it was observed that the release of chemically similar and banned chemicals was beginning to take place. These chemicals, known as CFC11, are generally known to be used in coolers, foam making and stain removers. The use of these chemical species has been reported almost as close as nearly all countries since 2006, but has emerged in recent investigations of 14,300 tons per year since 2013.
Are Scientific People the Right Way to Avoid Climate Change?
Chemist Stephen Montzka, who runs the study, says the findings are incredible. According to the obtained data, the emission amounts of the chemicals are almost the same as 20 years ago. This shows that there is a problem.
If the use continues in this way, studies that prevent the depletion of the ozone layer will be undermined and the ozone tears will be re-exposed to dangerous dimensions it is thought to reach.
