Humans have been depleting the ozone layer with chemical products. The unintentional experiment started in the late 1920s, when Thomas Midgley and other industrial chemists began to produce ...

it rips apart the ozone molecule, leaving the layer thinner than before. In 1974, two scientists from the University of California called Mario Molina and Sherwood Rowland discovered the threat ...

The difference is actually quite slight – the ozone layer features the triple-atom oxygen molecule at a level of 10 parts per million (ppm), versus the level of 0.3 ppm seen on average in the ...

Their observations revealed that the annual ozone layer above the South Pole was ... CFCs (chlorofluorocarbons) are a type of ...

But scientists soon discovered that didn’t matter because these molecules were extremely toxic to the ozone layer! Turns out, when UV light hits a CFC molecule, it releases a chlorine atom which ...

Most ozone-depleting substances also contribute to global warming. By reining in these substances and protecting carbon sinks ...

much of the ozone layer will have recovered. However, the report predicts that the polar regions will take two decades longer to recover. In a world where we increasingly hear reports of climate ...

June 16, 2021 — Ozone is a pollutant at ground level, but very high in the atmosphere's 'ozone layer,' it absorbs damaging ultraviolet radiation. Past studies have examined ozone levels in the ...

Oxidation is the process of combining a molecule with oxygen, and since ozone (O 3 ... above the Earth’s surface—where a layer of ozone absorbs harmful ultraviolet radiation (see article on p. 12).

If you like the smell of spring roses, the sounds of summer birdsong, and the colors of fall foliage, you have the stabilization of the ozone layer to thank for it. Located in the stratosphere, where ...
