Russian environmentalist Igor Shkradyuk said several instruments should be launched to monitor ozone-depleting substances. Then we will get a clear picture of how to reduce emissions into the atmosphere.
In an interview with the Izvestia newspaper, the scientist commented on the UN report on the return of the ozone layer to what it was in 1980, that is, before the formation of the ozone hole, which indicates that this will happen in the Antarctic in 2066, in the Arctic in 2045. and in 2040 in other regions.
According to him, a whole group of substances can destroy the ozone layer, including organic compounds containing primarily chlorine, bromine and iodine.
He says: “These substances stay in the atmosphere for different times. They usually have a very low concentration, so very sensitive measuring instruments are required to control them. It’s a tricky business.”
He points out that the United Nations report contains a large number of measurements recorded in different ways.
He says: “It turns out that the percentage of ozone-depleting substances decreases in the upper atmosphere (50 km and above), so it is easy to restore the amount of ozone. But at or below the flight altitude of an airplane, the amount of ozone does not increase, because a lot of harmful substances are emitted from the earth. And that humanity emits a small amount of harmful substances that do not dissolve in the atmosphere and rise to its upper layers.
He adds, but humanity is still emitting a large amount of substances that quickly decompose into the atmosphere up to a height of 50 km, so our task is to reduce this amount.
He concludes: “Overall, the authors of the report are confident that efforts to reduce emissions will have a positive impact and the atmosphere will become cleaner. The picture here is complex and incomplete compared to climate change and the amount of greenhouse gases. Therefore, more instruments should be launched into space to monitor ozone in ozone layer.
