Whoa, I am shocked to read that what seems to be a bright lecturer does not believe in the depletion of the zone layer or the ozone layer as a whole for that matter.

Also his definition of science is rather unscientific, with such a view quantum physics would not be science...

Anyways great article, before reading this I understood the concept but not the details so thanks for that!

PS: Is it possible to estimate the rhythm of depletion? Even if it is, I think most people that do not believe in the depletion and global warming will not change their minds... Especially with leaders like Trump :
