The Montreal Protocol that banned ozone-depleting chemicals excepted carbon tetrachloride and other chemicals used as feedstocks for production of other substances, assuming that their usage would stay low and decline. However, atmospheric concentrations of these feedstocks are increasing, delaying recovery of the ozone hole.

Today is a good day. Today is the birthday of the Montréal Protocol.

Adopted on September 16, 1987, and ratified by every UN-member state, this landmark treaty stands as the shining example of what humans can achieve when science, diplomacy, and collective action unite for our common good.

A mere 10-15 years after researchers had come to a consensus that chlorofluorocarbons (CFCs) were the cause of an expanding hole in the #ozone layer, international diplomacy defeated corporate interests in a battle for our future.

CFC emissions were reduced and eventually banned. The result of the Protocol is an ozone layer hole recovering, no longer expanding.

But aside from the tangible outcome, this day is about what the Montréal Protocol represents: facing uncomfortable truths, recognising the urgency, setting selfish interests aside in the pursuit of shared interests.

It’s #solidarity. We did it once, we can do it again.

Enjoy your #MontrealProtocol day, everyone.

@sundogplanets TIL about the #MontrealProtocol - thank you!

Proof that #EnvironmentalPolicy works: "During the peak of #ozone depletion season, the 2024 area of the #OzoneHole ranked the seventh smallest since recovery began in 1992, when the #MontrealProtocol, a landmark international agreement to phase out ozone-depleting chemicals, began to take effect."

"We need to initiate discussions as soon as possible. With space debris, it took us 20 or 30 years to define a solution. With [the satellite air pollution] problem, if we move on the same kind of timescale, it might be too late."

The ozone hole above Antarctica will keep opening up each spring for decades to come

"The ozone layer is a vital planetary boundary that protects all life on Earth from the sun’s damaging ultraviolet radiation.Ozone depletion is also linked with climate change, and there are other emerging issues which could affect ozone recovery. These include more frequent mega-wildfires due to climate change, emissions from rocket launches and more satellite debris burning up in the upper atmosphere. Recent research shows mega-wildfires such as the Australian bushfires of 2019 can contribute to ozone depletion."

Leah Stokes (Prof climate + energy policy UCSB,
working at/with Rewiringamerica.org )
interviewed #KamelaHarris on Oct 18 2022 on climate policy and her personal climate history.

Two things I recall after watching it:
1) Kamala thinks the Australian administration is climate-aware... 😁 #AUSPol
(And I thought: "oh well, this wrong verdict certainly shows the little grasp she has of what is really necessary to combat climate change...)

2) The #KigaliAgreement was signed and ratified by the US when Biden took office.
It's an extension to the #MontrealProtocol that curbed #ozone-killing emissions. The Kigali Agreement aims to phase down (not out) a cooling agent or compound called HFC which – if phased OUT – could reduce global warming by 0.5°C.

Kamela's ecological awareness has permeated through her professional career. So it's doubly sad to realize how badly she misjudges what needs to be done regarding climate. Because she might THINK that she's got it – due to her long ecol-history. But she really doesn't. And she doesn't know that she doesn't know, and therefore likely won't realize soon enough that she doesn't.

@Lee_Holmes

Yes, I agree it's a valid question and line of reasoning; however, it doesn't work for this conversation because the IVT you are trying to use doesn't account for the global impact of the actions. There is no acceptable amount of ODSs to be released.

You are also overlooking that it is not only bad for the environment to release ODSs, it's also against the law.

Hell, it's one of the few things almost all countries in the world agree is a bad thing to do.

Freon units stopped being produced 1/1/2010. Part production stopped on 12/31/2019.

The average life of an AC unit is 10-15 years; if you maintain it well, you can extend that a bit.

So, your unit is at least 14 years old. I think it's okay to retrofit or replace it.

Manufacturing a new AC unit is what 5 metric tons of CO2?

Running a new AC unit will be ~2 tons of CO2/year.

A 14-year-old unit that doesn't have the same energy consumption requirements as a new unit I'm sure uses much more than that (depending on the energy source of course)

1 ton of HCFC-22 (R22) has the same impact as 1,810 tons of CO2.

.5kg of R22 leaked ~= 1 ton of CO2, but this is just the warming effect, R22 will also deplate the Ozone.

So you are looking at least 3 tons of CO2/year released by your old busted unit.

So roughly, starting in year 3, it will be more environmentally responsible.

But this is a bad way to look at it; you are going to have to replace the AC unit or retrofit it regardless, so all you are doing is trying to make a case to unnecessarily harm the ozone for a couple of extra years so YOU receive a better value.

The problem of plastic pollution is too big for any one nation to handle. That’s why we need a global approach. It’s worked before with the ozone layer and acid rain and it can work again with plastic.

The #MontrealProtocol meeting in Nairobi, Kenya concluded on Saturday. It continues making progress on Ozone Depleting Substances (ODS) and in addressing #ClimateChange.

"decline in ODS emissions due to compliance with the Montreal Protocol avoids global warming of approximately 0.5–1°C by mid-century, with another estimated avoidance of 0.3–0.5°C warming by 2100 from the anticipated phase down of HFCs under the Kigali Amendment."

Very detailed summary by ENB/IISD: #MOP25 #ClimateDiary

✡️ Today's Jew of the Day is Susan Solomon!

Susan Solomon is a climate scientist notable for being the first scientist to identify chlorofluorocarbons as a major contributor to the hole in the ozone layer. During the 1980s, Solomon's research and expeditions showed elevated levels of chlorofluorocarbons in the atmosphere, and the mechanism by which they could be degrading the Ozone layer, an atmospheric barrier that protects the earth from solar radiation.

Her work directly lead to the UN Montreal Protocols, a plan to save the atmosphere through reduction in harmful chemical generation. This has largely been a success and the ozone layer is healing.

Solomon's work has been recognized as crucial by many institutions and she's been granted awards by including the National Metal of Science, the French Metal of Science, the UK Royal Society, the National Women's Hall of Fame, and Time Magazine, amongst others.

"PFAS present challenges to the Parties to the Montreal Protocol, as they have been proposed as alternatives to some ozone depleting substances and substances with high GWP. Discussions on this issue will likely continue for some time."

The Montreal Protocol, an international treaty that phased out ozone-depleting substances, has also helped delay the loss of Arctic sea ice by decades. A new study shows that without the protocol, the Arctic would have lost almost all its summer sea ice by 2023. The study highlights the benefits of global cooperation and the need for more action to protect the climate.

"Here, analyzing new climate model simulations, we demonstrate that the Montreal Protocol, designed to protect the ozone layer, is delaying the first appearance of an ice-free Arctic summer, by up to 15 y, depending on future emissions. We also show that this important climate mitigation stems entirely from the reduced greenhouse gas warming from the regulated ODSs, with the avoided stratospheric ozone losses playing no role."
