Yeah, sure, okay, that whole Second Coming, Kingdom of Heaven thing turned out to be a dud, but we don't need all that, see? Eventually we'll be good enough at making these wonderful gadgets that we'll transcend humanity and maybe even God, too, out there jettin' around space high-fiving all the aliens. I have confidence in the bird-men who come after us, that they will find some treasures in our wreckage

The ozone hole is kind of a good comparison because it was solved with... a massive planet-wide effort to eliminate use of CFCs. It was not solved by waiting 50 years in the hope that we would develop cfc sequestration technology or something like that So I guess we just need to do the same thing with fossil fuels.

The success of the campaign against freon is also part of the reason fossil fuel companies kicked denialism into high gear in the early 90s, because they saw what would happen to them

I’m convinced some of the naysayers here are paid to spread misinformation on climate action. There are commenters on this sub that say we should literally give up and do nothing, despite the science telling us we can still limit warming to 1.5c if we cut global emissions 45% by 2030 and hit net zero mid century. The defeatism is absurd.

If the ozone layer had been mostly or completely eradicated, the increase in UV radiation at Earth's surface would have doomed most of the animal kingdom on a relatively short timescale. Plants and fungi might have made it, but the ecosystem would have been radically different if it ever even reached equilibrium again. It was absolutely an existential threat.

The defeatism is absurd. The defeatism isn't about feasibility. It's about politics and real power. The purpose of a system is what it does and our system pumps out more CO2 and Methane YoY until constraints prevent us from doing so. The goals of every industrialized capitalist nation on earth are at odds with taking action on the climate. It's a gun fight where everyone has their Petroleum Super Soaker out pointed at their economy. Everyone is in agreement that if we keep spraying our crops and transportation and shipping and construction industries with juice, we'll destroy everything. But also the country that manages to use the most, before we stop wins the game of musical chairs we are playing beforehand. So no one will ever stop.

mdemone posted:the large majority of plants would not be able to sustain photosynthesis and would die within days or weeks. Do you have a link I could read more about this at? The wiki page only has vastly more minor impacts: quote:Depletion of the ozone layer and allowing excess UVB radiation would initially be assumed to increase damage done to plant DNA. Reports have found that when plants are exposed to UVB radiation similar to stratospheric ozone depletion, there was no significant change in plant height or leaf mass, but showed a response in shoot biomass and leaf area with a small decrease.[81] However, UVB radiation has been shown to decrease quantum yield of photosystem II.[82] UVB damage only occurs under extreme exposure, and most plants also have UVB absorbing flavonoids which allow them to acclimatize to the radiation present. Plants experience different levels of UV radiation throughout the day. It is known that they are able to shift the levels and types of UV sunscreens (i.e. flavonoids), that they contain, throughout the day. This allows them to increase their protection against UV radiation.[83] Plants that have been affected by radiation throughout development are more affected by the inability to intercept light with a larger leaf area than having photosynthetic systems compromised.[84] Damage from UVB radiation is more likely to be significant on species interactions than on plants themselves.[85] To be clear I’m not disbelieving you, just want to educate myself better.

Total destruction of the ozone layer would lead to orders of magnitude more UV-B radiation than can even be achieved in a controlled experiment. I'll poke around for something but that sort of thought experiment doesn't usually get written up, lol edit: this is a pretty good review article on UVB effects in plants https://www.researchgate.net/profil...c-Processes.pdf mdemone has issued a correction as of 18:45 on Nov 7, 2022 |

also the hole in the ozone layer is absolutely still a massive problem, it's just that the depletion is now mostly under control and contained to the antarctic which i'm sure has no long term knock on effects one fun side effect of moving from CFCs to HFCs is that the latter are themselves a direct contributor to atmospheric warming so in conclusion, lol lmao

Going back to the original tweet by the dufus, if total destruction of the ozone layer was far further away then climate change, I still don’t think I would consider it more of an existential threat than climate change.

That would be true in our case today. However in the CFC era it was not out of the realm of possibility. A significant fraction of the planet's ozone was lost, due to a technology that had only been around for 2-3 decades at most. Had the Montreal Protocol not been enacted when it was, the ozone layer plausibly could have been destroyed by now. See isn't it nice to doomsay about something that *isn't* happening? Feels good man!

when they taught me climate stuff a way back i distinctly remember them saying that the modelling that lead to the montreal protocol(which got rid of cfcs) showed : business as usual with cfcs>> human extinction by 2060ish due to all crops/plants dying it was held up as a shining example of how international cooperation can work to solve global problems i'll have to check if i have any of the model data/studies from the time

Seems strange the Mississippi, Yangtze, Tigris, Parana, Danube, Po and Loire Rivers are all drying out at the same time. Fortunately, it's not a big deal since most economic activity happens indoors.

 King Charles III Hosts A Reception At Buckingham Palace Ahead Of The Cop27 Summit LONDON, ENGLAND - NOVEMBER 04: King Charles III plants a lime tree near the Tea House in the Buckingham Palace garden, for the Queen's Green Canopy (QGC), after hosting a reception for world leaders, business figures, environmentalists and NGOs, at Buckingham Palace ahead of the Cop27 Summit on November 4, 2022, in London, England. King Charles III will miss the gathering of world figures in Egypt next week but is likely to discuss issues around Cop27 and climate change with those invited to his royal residence.
