Australian Wildfire: Australia’s fires have reduced the ozone layer, new study

You must remember how two years ago the fire in the forests of Australia brought disaster. Millions of creatures were killed. The forests spread over acres were reduced to ashes. But its effect was not only on the ground. The atmosphere and above it have also been seen below. The smoke from the Australian forest fires did not spare even the ozone layer. He also diluted it with his poison.  

After studying for two years, scientists have told that the smoke and pollution from the Australian forest fires had reduced the ozone layer by 1 percent. This is such a big side effect, which will take ten years to recover. That is, it will take a full 10 years to compensate for 1 percent loss in the ozone layer. Think how big a loss this is. 

This study has recently been published in the Proceedings of the National Academy of Sciences . In which it has been told that if forest fires continue like this, then the climate crisis will not end. Also, the recovery time of the ozone layer will increase. The ozone layer is part of the second layer of the Earth’s atmosphere, the Stratosphere.  

The ozone layer protects from ultraviolet radiation coming from the sun. Inside which there is a very high density of ozone particles. When scientists did a satellite study of the Australian wildfire, it was found that the smoke aerosols reacted with the nitrogen present in the stratosphere. The chemical process that led to this led to a reduction in the ozone layer.

Dr. Ken Stone, an environmentalist at the Massachusetts Institute of Technology (MIT) and co-author of this study, said that the ozone layer had decreased from March 2020 to August 2020. As the wildfire aerosols slowly started leaving the stratosphere and headed towards Earth, the depletion of the ozone layer began to recover again. That layer stopped thinning. But it was short time subtraction, which could be dangerous in future.  

Dr. Ken Stone said that the ozone layer recovers one percent every decade. The ozone layer in our atmosphere continuously fills over the tropics. Because there sunlight reacts with oxygen to form ozone. Despite the continuous formation of ozone, its layer is getting weaker and thinner. This is because of chlorofluorocarbons (CFCs), which were banned in 1987 under the Montreal Protocol.
