“The Montreal Protocol on Substances that Deplete the Ozone Layer is effective and working. Since the entry into force of this multilateral environmental agreement, there has been tremendous progress in global efforts to repair the ozone layer. As a consequence, there are now early signs that we are on the road to recovery of this precious life-support system.”
Kofi Annan — September 16 2006
“If the emissions were to persist, then we could imagine that healing of the ozone layer, that recovery date, could be delayed by a decade.”
Dr Stephen Montzka — US National Oceanic and Atmospheric Administration (NOAA) — May 2018
“It is difficult to get a man to understand something when his salary depends on his not understanding it.”

July 15 2019 — As we mark the 3 year anniversary of our blog, let us take a look at the stories we posted on July 15 2016, 2017 and 2018. And never forget. History must be lived forwards, but it can only be understood backwards.
July 15 2018 — The Montreal Protocol is an extraordinary success and a testimony of what humankind can achieve when there is a universal will to fight for its survival. According to computer simulations, the recovery of the ozone layer in the mid-latitudes and the Arctic was anticipated around 2050 — five years later than previously estimated — while in Antarctica, recovery is expected by about 2065, about 15 years later than the previous estimate.
However, according to a recent study, published in Nature on May 16 2018, the atmospheric level of trichlorofluoromethane — also known as CFC-11 — is not declining as quickly as expected. And this is bad news because CFC-11 is a ozone-depleting chemical banned by the Montreal Protocol. Scientists with the US National Oceanic and Atmospheric Administration believe that someone is releasing thousands of tons of CFC-11 in the atmosphere.
