NASA had been very quietly monitoring it for years. The data was available on their website. I remember linking it to someone on TDW in 2019. It was getting smaller but at the time never went away (because there IS still one country using CFCs. No points for guessing which one.)
They learned a lot about ozone layer and holes in it. They know they have seasonal expansion and contractions. Cfcs were a contributing factor but with the ban on their uses we have seen repairing of damage and bigger holes. However, there are now massive holes over India and China from their pollution and it is illegal to blame third world shitholes for pollution, so illegal to discuss ozone layer.
There are no ozone holes over India and China. You don't need to spread fake news to make a point that China and India are major polluters.
Ozone is created through sun radiation. The reason we had a big ozone hole over the Antarctica was because over the winter months the lack of sun radiation combined with the destroying effect of CFCs in the atmosphere on ozone led to a big hole. China and India on the other side are near enough the Equator, so sun radiation is never lacking and ozone is produced all year around.
Did you go to an Amish school or something?
It's well known global use of CFC's was responsible for the Ozone hole, and has begun healing itself since they were phased out.
Because we put regulations up. There are caps how much SO2 (which causes acid rain) provinces can emit now. SO2 emission are down by over 80% since the 1980s. And the use of CFCs is pretty much verboten due to the Montreal protocol.
You're absolutely wrong on this. Manufacturing a car or manufacturing a TV doesn't cause SO2 emissions. Burning coal, natural gas and oil causes SO2 emissions.
You said that you are going to move to Saskatchewan. Get ready to hear stories how lakes are filled with dead fishes every few years because increased oil production at the Athabasca oil sands causes acid rain in Northern Saskatchewan. And when the ph value of a lake drops below 4.5, then it's a dead lake. This is caused by acid rain.
Acid rain is a very local phenomenon. How much SO2 China emits through burning coal and oil has almost no impact on the environment in Canada.
What country has very lax environmental protections? Where are these goods shipped from and how?
While our manufacturing was outsourced, out energy production wasn't. Canada's energy output didn't go down. We still burn coal, natural gas and oil for power. Over 90% of the power generated in Alberta and Saskatchewan is through fossil fuels. In Saskatchewan we have the oldest and dirtiest coal powered plants in Canada, and probably in North America. 60 year old power plants like the Boundary Dam station are 10 times worse than a modern natural gas powered plant.
Since that time we have learned that it wasn't the oilsands
It is the oil sands. Even the government of Alberta admitted it. If it wasn't the oil sands, then how do you explain that the Athabasca and surrounding region are the most affected? You don't hear much about acid rain in the eastern part of Saskatchewan, but it's another story on the border to Alberta. Even today and not only 10 years ago. The Syncrude oil plant in Fort McMurray spews out tens of thousands of tonnes SO2 into the air. And it all comes down with the next rain.
My long term solution? Invest in nuclear power
No one is going to invest in nuclear power when the costs of a 1 GW reactor are about $20 billion or more. Saskatchewan doesn't have the money for it.

You win a no-prize!

wow. It's almost like we're living in a churning bubble of fluid that ebbs and flows.
I remember when it was all about save the rainforest! Reduce paper and use more plastic!
Now it's use more paper and less plastic?
Because we put regulations up. There are caps how much SO2 (which causes acid rain) provinces can emit now. SO2 emission are down by over 80% since the 1980s. And the use of CFCs is pretty much verboten due to the Montreal protocol.
The cognitive dissonance in this thread is astounding. We've went from "Global Warming is a Hoax" to "All science is a hoax"
Fuck the ozone
