Montreal Protocol really works for the environment

Despite the fact that mankind continues to engage in industrial tasks that are not quite useful for the Earth’s atmosphere and receives more and more warnings from leading world ecologists about irreversible climate change, we can still say that we managed to significantly suspend these changes. At least this is indicated by environmental experts from several US universities, who today presented the results of their long-term statistical study on identifying the real benefits of the so-called Montreal Protocol, signed in the 80s. of the last century, whose goal is to reduce emissions of chlorofluorocarbons.
Because it is these compounds that represent even greater danger than ordinary greenhouse gas rising to the upper segments of the Earth’s atmosphere – and the signed Montreal Protocol, according to research by environmental experts, actually managed to minimize the rise in the temperature of the planet’s surface and atmosphere by about 25%. The joint team of researchers came to such conclusions soon after considering an alternative scenario in which this protocol was not signed and ratified, and in this scenario the temperature would rise by about 1 degree Celsius by the middle of this century – instead, the increase only refers to an indicator of 0.12 degrees Celsius, which is much less.
Moreover, most of the signatories to the Protocol managed to get rid of the by-products of chlorofluorocarbons, which significantly improved the state of the ozone layer over the Antarctic, where a rather large ozone hole was recorded at the end of the last century.
Nevertheless, the attention of scientists at this point in time is more focused on the development of additional statistical scenarios, which could demonstrate an even more noticeable difference between the current consequences of the signed Montreal Protocol and some other scenarios. In particular, they are preparing a new simulation package of studies on this subject, the results of which are sure to be reported later.
