The Impact of Montreal Protocol on Repairing the Ozone Hole

[Auzie]

Article in SMH, Model shows what ozone layer would look like without Montreal Protocol

An ozone hole larger than Australia would have opened up over the Arctic if we had continued to use CFC for the last three decades.

In 1987, countries agreed to Montreal Protocol which restricted the use of harmful ozone depleting chemicals.

It is expected that the ozone hole will be fully repaired by 2050.

Well done everyone, team effort yields good results.

The article references study published in Nature Communications, Quantifying the ozone and ultraviolet benefits already achieved by the Montreal Protocol

How come all the lobbying/lying money from "Big CFC" didn't derail the Montreal Protocol? Oh, yeah, the chemical companies actually make more money from the replacement refrigerants.

NOTE: 1987 and above report 2015 and now, surprise, surprise it is more complicated than we originally thought. And is usual new things discovered largely by accident. I find fascinating and hope you find informative as well. I think 2016

2016 ?? - WTF; these academics don't DATE anything?? see the 2016 in below description

[Harvard report claims little to no methane CH4 released from Deep Water Horizon Oil Spill - wonder who paid for that study and how much do I trust the professors numbers - in my case, not much.

Seems from 2015, much has changed, and to me it show why Harvard continues to become more irrelevant all the time. Protect the elites, care not for the rest of us. Sad.

Seems the Ozone hole is the largest ever. I'm not sure where the optimism is coming from? Just People that can't face up to the fact that they have failed?? Looking to the "bright side?" anyway, below is a fine documentary: 2015 - has all research stopped since 2015? has it ended since Trump elected? probably.

The lack of improvement in the Ozone layer is due to cheating. In China. I am not surprised.
