What’s the latest with the ozone layer?

Envirotec Magazine

On 16 September, the world marked the International Day for the Preservation of the Ozone Layer. The European Space Agency (ESA) takes a closer look at this year’s ozone hole. The ozone layer in the atmosphere protects Earth from potentially harmful ultraviolet radiation. Ozone depletion is greatest at the South Pole.

We’ve got another ozone problem, and it’s not what you think

Grist

Most of us know ozone as that benevolent stratospheric layer that absorbs the sun’s harmful UV light and keeps us safe. In the 1980s, scientists found a “ hole ” in the ozone layer — really just a large section that was getting precariously thin — caused by the use of potent chemicals called CFCs. In fact, we already have.

Effect of COVID-19 on Environment

Due to air pollution the ozone layer gets depleted and that was nothing but an indication of increasing global warming. The above image shows how much pollution level was in 2019 and hence ozone layer was disappeared. In the above image in 2020 there is an appearance of ozone layer due to the deduction of pollution level.

This year’s ozone hole could be the smallest it has been in 30 years

AGreenLiving

For decades, scientists have closely observed the ozone layer , which protects Earth from the sun’s harmful ultraviolet (UV) radiation. Ozone is created in our atmosphere when the sun’s high-energy UV rays rupture the stable covalent bonds of atmospheric oxygen (O2) molecules, transforming them into free radicals.

m/m3 was exceeded in 43% of all the cities analyzed, while in 2019 this had dropped to only 41%. The cities with the worst increases in this pollutant between 2010 and 2019 are predominantly in India. over 2010-2019. At the same time, Beijing has expanded its monitoring system from 35 stations in 2013 to over 1000 in 2019.

Less air pollution leads to higher crop yields, says study

Envirotec Magazine

These gases can directly damage crop cells and indirectly affect them through their role as precursors to formation of ozone, an airborne toxin known to reduce crop yields, and particulate matter aerosols that can absorb and scatter sunlight away from crops. Nitrogen oxides, or NOx, are among the most widely emitted pollutants in the world.
