So what's the story with CFCs anyway? Did we really stop using them? Did that have a material impact on the amount in the atmosphere? Was there ever a problem? Curious about this one, thanks!
Standard "we're all doomed bc climate" story, and is retweeted as such Actually, a story of how we've cleaned up CFCs, so they begin outgassing from oceans CFC11 used to be 270ppt in 1990s. Will keep declining, and w/extreme climate we can detect 0.5 ppt in 2145 at 50ppt (~1%) https://twitter.com/themadstone/status/1371816390055845889 …pic.twitter.com/ymLV1erpyh

Was a problem (vastly exaggerated, but real problem, that would get worse) We've most fixed the problem through innovation (substitution of CFCs with less problematic substances) Yet, we're surprised ozone hole over Antarctic not getting smaller, but likely happen in future
