14:22:20 From  Dave Dougherty  to  Everyone : In 2020, the Antarctic ozone hole was one of the biggest (~25 M km2) and longest lasting in the last 40 years.  How 
confident are scientists that the Montreal Protocol, which has essentially eliminated CFCs, will eventually prove sufficient to close the hole and allow ozone levels 
around the globe to return to natural levels?

14:32:56 From  Bob Jones  to  Everyone : Comment from Bob Jones.  I invited Alex Chisholm to this session but his internet in rural central ontario was not sufficient to 
join.  Alex, Bill Pugsley, and I were on the same meteorologist course.

14:32:59 From  Tim Leah  to  Everyone : Vic, any comment on recent (in the last couple of years media reports indicating a recurrence of CFC-11 ( I believe) production in 
China?  Haven't heard anything lately.

14:36:02 From  Dave Dougherty  to  Everyone : BBC News said R-11 was traced to China.  https://www.bbc.com/news/science-environment-48353341

14:36:33 From  Jon Legg  to  Everyone : Considering that the political belief seems to be that growth is good.  We now know that growth of demands on the planet is 
an underlying reason for climate change.  Would a group of this be too large and unmanageable?

14:49:20 From  Peter Stoett  to  Everyone : Thanks this was excellent—need to run, but I hope Vic will write down his unique perspective as future historians of global 
environmental governance will benefit immensely.

15:04:35 From  Dave Dougherty  to  Everyone : CO2 equivalents can be found here, among many places.
