remember that time I went to the doctor and he prescribed me antibiotics and then I got better. man, what an alarmist he was.
in reality, of course, ozone depletion was the 'bullet that missed'

@andrewdessler What gets left out of this narrative, of course, is the fact that the manufacturers of fluorocarbon refrigerants stood to make better profit margins from the ozone-friendly replacements than the old ones, most of which were no longer protected by patents. This is the sole reason that the Montreal Protocol succeeded.
Fossil fuel companies do not have an analogous plan B.
@phil_stevens @andrewdessler And it may have been better for the environment if we'd just banned their use in contexts vented to the atmosphere (aerosol propellant) but kept them as more-efficient refrigerants.
@dalias @phil_stevens @andrewdessler all CFCs used for refrigeration were eventually vented - recycling infra was nonexistent, and refrigerators get old, leaky, destroyed.
@fgcallari @phil_stevens @andrewdessler Yes but the volume is vastly lower, and handling reclamation with deposit (get $200/kg back for what's still there) could have incentivized it well enough.
@phil_stevens @andrewdessler the oil companies could have invested non trivial amounts into solar wind and nuclear but they didn't and went all in on oil and gas and now can't back down so we gotta get rid if them now
@fluffykittycat@furry.engineer @phil_stevens@mastodon.nz @andrewdessler@mastodon.world yeah, green energy sources are quickly becoming cheaper than non renewables. it wouldve gone even faster had there been more investments.
in regards to the "availability" issue, it's completely an engineering problem. analogous to saying there's no way to fly to the moon cuz we've never done it before.
@ashten @phil_stevens @andrewdessler yeah it's an engineering problem and the solution is have some nuclear reactors and maybe fincially incentivize demand shifting by pricing electricity by the hour of the day. It's cheaper than totally bananas gobsmacking climate change (actual scientists words)
Also refrigeration and deodorant businesses are small relative to fossil fuel ones. For ozone depletion remedy international organisations actually had some sway.
@TenPastTwo @phil_stevens @andrewdessler I co-wrote a paper of the GHG benefits of the #MontrealProtocol in 2012 . Chapter 23 https://www.eea.europa.eu/publications/late-lessons-2/late-lessons-2-full-report/late-lessons-from-early-warnings/view
@andrewdessler@mastodon.world
And probably the last time they listened to scientists! 
@andrewdessler dude probably thinks Y2K magically solved itself too.
@andrewdessler The hole is still here, opens up every Southern spring…
@pandanus @andrewdessler wellllll shit. 
#FBPE 
@moondog548 @pandanus @andrewdessler It's still healing, but healing it is. I remember them saying it would take many years.
@andrewdessler I keep reading the same about "remember when we were told the horrors of acid rain and then we stopped hearing about it!"
Like, lill me could measure the pH levels in the rain here in Norway (and I did!! Lill geek kid me). But they still wanna tell me that I was brainwashed.
@andrewdessler Also, we have been seeing an absurd amount of mother of pearl clouds the past weeks, so I am not sure I wanna write off the ozone issue quite yet :/
@andrewdessler YES!

Matt Walsh is such a knob.
@andrewdessler The bullet we dodged. But this damn train heading for us is too big to dodge, we'll just have to stay here on the rails. Maybe try running along them, away from it.
@andrewdessler Yeah and I remember leaded gasoline as well... car freaks expected their vehicles to be impounded and destroyed on the spot when they actually could just add a tiny amount of additive.
