That was the hole above California. This hole is above Antarctica, apparently caused by emissions drifting from China.
Comment on The ozone hole above Antarctica has grown to three times the size of Brazil
GreenMario@lemm.ee 11 months agoI was told it was fixed. WTF?

Yeah, that’s what I heard too. And it was because of CFC’s and wasn’t related to climate change. Once CFCs were outlawed, I heard the hole in the ozone was fixing itself (and ultimately fixed).

Seen a lot of “trades” videos out of china with refrigerant cylinders in the back that look suspiciously like R-12 and R-22 cylinders.
You know, the refrigerants that were eating into the ozone layer.

Fucking hell. Thanks China.

They signed the Montreal protocol, which is what banned cfcs internationally.
But that doesn’t stop them from either using existing stockpiles, although I don’t know how they still have a significant amount of either, or ignoring the treaty altogether.
CFCs are actually amazing refrigerants. They are low pressure and were fairly cheap to manufacture compared to modern refrigerants. The low pressure is nice, because it means the systems that work with those don’t need to be designed to withstand 400+ psi like you need for 410a for example. That also means installers on lower pressure systems only need to soft solder joints most of the time, instead of brazing the lines together. That’s the only reasons I can think of that they’d still be using damn CFCs.
