World International Ozone Day: Know Why the Hole Over Antarctica Still Isn't Closed

RE: https://mastodon.social/@sundogplanets/116138358977573385
What happens to all the man-made #satellites in #Earth's #orbit, of which approximately 15,000 are active, while the #lifespan of a satellite is usually only a few years? L. Revell et al. (2026) express concern in their #Conversation #article that the #throwawaymentality is causing so many decommissioned satellites to finally land in the #outeratmosphere that their #fragments and burnt #dust are #exacerbating #climatechange and #ozonedepletion.

Think CFCs were bad? Meet BFCs! But in the hands of my timeline, it makes for something more optimistic...and exotic.

Ozone–oxygen cycle (Biogeochemical cycle 🔄)
The ozone–oxygen cycle is the process by which ozone is continually regenerated in Earth's stratosphere, converting ultraviolet radiation into heat. In 1930 Sydney Chapman resolved the chemistry involved. The process is commonly called the Chapman cycle by atmospheric scientists. Most of the ozone production occurs...

There's a natural variation in ozone in the atmosphere, but CFCs and other substances were reducing ozone levels and expanding the seasonal ozone holes over the poles. The problem was real and it was getting worse, because CFCs were produced for a reason: It was really useful and cost-effective stuff.
Banning ozone-depleting substances for use as coolants, fire supressants, aerosol propellants and other applications was very successful, and after four decades we are now more than halfway to recovering to natural ozone levels.
A few years ago there was briefly some illegal production of CFCs, which halted the recovery, but it was tracked down and halted, and we are back on track.

Do you cosplay as your study species on your title slide or is that just me? 🌱🇦🇶🫶

Last week I presented some of my labs research at the joint Ecological Society of Australia & Society for Conservation Biology Oceania conference #ESASCBO2022
My talk was on how #ClimateChange & #OzoneDepletion are affecting the moss beds in East #Antarctica, given on Dharawal Country
So many great discussions, ideas, introductions and reunions were facilitated last week. Thank you to the organizers, both local & national!
If you were at the conference, let’s connect!

Catch me at #ESASCBO2022 next week ☀️
I’ll be chatting about how #ClimateChange & #OzoneDepletion are effecting #Antarctic mosses in the ‘Species Response to Climate Change’ arvo session 2.30-2.45pm on Monday ✌🏻
A part of the climate that has influenced terrestrial flora in Antarctica is the Southern Annular Mode, or SAM, which determines the strength & position of the westerly wind belt around the Southern Ocean (& influences Australian weather too) 🌬🥶

RT @CopernicusECMWF: Thanks to #MontrealProtocol, which aims to protect the ozone layer by phasing out chemicals, like CFCs, HCFCs etc, #ozonelayer is slowly healing but it will need at least 40 years to fully recover.
