The Antarctic Ozone Hole — From Discovery to Recovery, a Scientific Journey

While the ozone hole has been considered by some as a solved problem, in fact its recovery is still many decades away and the effects and interactions of ozone depletion on climate change are just starting to be understood. On the 16th September 2011, embark on an investigative journey through the history and science of the ozone layer, the actions taken to address this major environmental threat and the consequences both for the ozone layer and climate system. This short film seeks out explanations and answers from the scientists closest to the issue.

    The key words in this video are “researchers apparently discovered”. Molina, Crutzen, and Rowland deserve to have their Nobel award stripped. Jonathan Shanklin is also severely deceived — his research looked up at one point (one column of the atmosphere), and did not measure chlorine levels. The data on ozone depletion has never been properly linked to an increase in the use of CFCs. Satellite data only show the changes in the ozone — not the alleged CFC atoms “splitting” into chlorine atoms.

    Ah, I see it was a mixture of both!

    You are ignorant, do some research before you open your trap, or write your (dullard-minded) comment.

    His prediction has yet to be proven to ever occur. 50 years is an extremely small fraction of the age of the earth…

    yes, yes it is BUT that would require us to stop the montreal protocol. If i were you, i woulnt try this

    That’s exactly why aerosol hairspray should be banned.

    I’m a bit concerned about this, to be honest.

    Not quite right, go find some books on the subject and learn something.

    is it possible for the depletion occuring over antartica 2 lead to destruction of the entire ozone later?

    Wait a second, aren’t the ozone holes always above one of the poles on Earth? Isn’t the hole above the pole experiencing winter for like 6 months? Isn’t ozone created from the chemical reaction of sunlight and oxygen? Yea from what I’ve come to understand, this “ozone layer” is nothing more than the Ionosphere and anywhere there is a hole is just a place where the chemical reaction isn’t happening. Put that in your pipe n smoke it….

    Yeah, but like the dude said, if CFCs continued to be released into the atm then there’s 2/3 of the ozone gone. You can die from over exposure to UV radiation but I would rather not, thank you. There are alternatives than using CFCs.

    “and on the surface of these clouds are chemical reactions that convert chlorine compounds to very efficient compounds.” what?

    The real reason behind this “BS. Documentary,” is to introduce the carbon tax law, the US. (Corporate Controlled Government) now wants to charge people for air: plants absorb carbon dioxide and monoxide thus giving off oxygen. The earth it’s self releases these gases naturally through volcanic activity and other craters…more than all, of mankind.

    There’s is a hole in the ozone, but that was cause by nuclear weapons tests, do the research, not meaning on those (Wiki sites)!
