Climate change horror: How global warming helped a mass extinction event on Earth

The researchers found hotter summer temperatures across entire continents contributed to more water vapour being transported into the atmosphere.

With the water vapour, organic compounds produced by plants and fungi were carried to the ozone layer.

Once in the atmosphere, the compounds were free to release chlorin, which can break down ozone molecules – a compound of three oxygen atoms.

And though scientists have announced in April this year a record-size ozone hole in the Arctic has patched up, Professor Marshall believes global warming cold still negatively impact years of progress.
