Good News! Improvement seen in the ozone layer that protects the earth, this big change will happen by 2066

The continuous warming of the Earth can now be said to be a cause of concern for every human being living on this planet. The increasing temperature of the earth every year is causing severe heat waves in some countries. Its long-term consequences are said to be very frightening. But meanwhile a good news is also coming from scientists. You must have heard about the ozone layer which is present in the earth’s atmosphere and protects living beings from the harmful rays of the sun because it prevents those rays from entering the earth’s atmosphere.

The ozone layer is becoming thinner every year. Every year a big hole appears in Antarctica. Chemicals and smoke emitted from industrial units cause great harm to this layer. But now at the end of 2024 a good news has come. This year the visible hole in the ozone layer has been found to be smaller. That means the loss has not been recorded as much as last year.

This shows that the ozone layer is recovering. Scientists from NOAA and NASA have monitored it from September to mid-October. They found that this time the hole in the ozone layer is the 7th smallest hole in history. That is, every year a huge hole has been seen in ozone seasonally, but this time this hole has been found to be very small.

According to the report of Earth.com, an agreement was made in 1992 to protect it, which is called Montreal Protocol. It has been said to contribute significantly in reducing the loss of ozone. The purpose of the agreement is to reduce the amount of chlorofluoro carbon (CFC). The finding of a small hole in the ozone layer this year is direct evidence that efforts have had an impact on this layer.

According to Dr. Paul Newman, head of ozone research at NASA, the Antarctic ozone hole of 2024 is much smaller than the hole of 2000. It has been moving towards improvement for the last two decades, the proof of which is now visible. However, this process is said to be very slow. But it is said that the chlorofluoro carbon present in the air is gradually decreasing. These may take several decades to end. Scientists estimate that if the recovery continues like this, then by 2066 the hole in the ozone layer over Antarctica will be completely filled.
