CLIMATEWIRE | Five ozone-depleting substances are increasing in the atmosphere, a new study finds, despite an international ban on their use and production.
CFCs are widely known for having depleted the Earth's atmospheric ozone layer through the 1980s. The five mystery CFCs are causing little damage to the ozone layer, the study says, but the climate impacts are substantial. In 2020, the five CFCs had a combined effect that was equivalent to about 47 million metric tons of carbon dioxide in the atmosphere.
A 2010 update to the agreement banned the production of CFCs for any purpose that would lead them to enter the atmosphere. In theory, that means they should all have been decreasing over the last decade. The supposedly climate-friendly replacement — HFOs — turns out to have climate impacts because CFCs are an ingredient in their manufacture and leak out during the production process.
Well let's see china doesn't give a shit and is billing coal plants without air regs, Russia is well working with China. Africa is working with China one road bs. I dont understand were these substances are coming from. Do better scientific am. A 11 can connect the dots better
I’m blocking you now too much fear mongering
Anyone want to guess if China is putting the environment ahead of world domination? Mysterious my left elbow. tt:DanHenninger
Gee whiz, maybe because if we’re the ones that ban it that it doesn’t stop others from still using it.
Let’s not go back to acid rain again, please?
Somebody’s being a bad boy…
The ocean will emit these as it heats up.
Is there anything that doesn’t cause global warming?
Act of God
They just said the ozone layer is healing itself stop the bullshit
When I did a superficial look into the historic accord that took Freon out of circulation I found an agreement in principle and no further action. I could certainly have overlooked something. Maybe you could commission a thorough history.
Mysterious. It’s China.
Everything in the world, now outer space contribute to,global warming. What a bunch of nonsense.
You mean China doesn’t play by the rules?
It's not that mysterious.
Ozone has been reduced before and we had nothing to do with it....
