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 ...

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 ...

Inbound air passes through a mesh inside the converter that’s coated in the catalyst, which grabs one of ozone’s oxygen atoms, letting a molecule of breathable O2 pass through. When another ozone ...

The British Antarctic Survey scientist Joe Farman, who helped identify the “hole” in the ozone layer over the southern ... including the Society of Chemical Industry (SCI) Environment Medal ...
