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

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.

A blog post about buying a new appliance. I don't do this often. In general I try to repair things instead of buying new. But in this case the old refrigerator (which was in our home when we moved here 17 years ago) was using an absurd amount of electricity. Our consumption will be about 600 kWh a year lower due to replacing an old fridge and an old freezer with a new A-rated appliance.

When old satellites fall into Earth's atmosphere and burn up, they leave behind tiny particles of aluminum oxide,
🔸which eat away at Earth's protective ozone layer. 🔸
A new study finds that these oxides have 💥increased 8-fold between 2016 and 2022 💥
and will continue to accumulate as the number of low-Earth-orbit satellites skyrockets.The 1987 Montreal Protocol successfully regulated ozone-damaging #CFCs to protect the #ozone layer,
shrinking the ozone #hole over Antarctica with recovery expected within fifty years.
But the unanticipated growth of #aluminumoxides may push pause on the ozone success story in decades to come.
Of the 8,100 objects in low Earth orbit, 6,000 are #Starlink satellites launched in the last few years.
Demand for global internet coverage is driving a rapid ramp up of launches of small communication satellite swarms.
#SpaceX is the frontrunner in this enterprise, with permission to launch another ⭐️ 12,000 Starlink satellites and as many as ⭐️42,000 planned.
#Amazon and other companies around the globe are also planning constellations ranging from 3,000 to 13,000 satellites, the authors of the study said.
Internet satellites in low Earth orbit are short-lived, at about five years.
Companies must then launch replacement satellites to maintain internet service, continuing a cycle of planned obsolescence and unplanned pollution.Aluminum oxides spark chemical reactions that destroy stratospheric ozone, which protects Earth from harmful #UV radiation.
The oxides don't react chemically with ozone molecules, instead triggering destructive reactions between ozone and chlorine that deplete the ozone layer.
Because aluminum oxides are not consumed by these chemical reactions, they can continue to destroy molecule after molecule of ozone for decades as they drift down through the stratosphere.

About that ozone hole..
Doesn't seem to be healing very fast - not due to #CFCs necessarily but a quirk of the #Climate system means a colder #Stratosphere - which is delaying things.
Really good piece from my colleagues at DMI on it (in danish but DeepL works really well for translation):

"The production of chlorofluorocarbons #CFCs that would ultimately be released to the atmosphere was banned globally in 2010 under the Montreal Protocol. […] However, ongoing emissions of the five CFCs of focus may negate some of the benefits gained under the Montreal Protocol if they continue to rise. In addition, the climate impact of the emissions of these CFCs needs to be considered, as their 2020 emissions are equivalent to 47 ± 5 TgCO2." [as much as the rest]

Ozone Layer to Recover in 40 Years: How We Got Here, and What Now?

Humans have never removed an #environmental pollutant on a regional or global scale that matters.
Our solution to environmental pollution has always been to reduce the pollutant at the source (e.g., #CFCs for stratospheric #ozone, SO₂ for acid rain, SOₓ, NOₓ, VOCs, etc. for urban air #pollution) and then let nature heal.
The solution to #CO₂ pollution might be the same. We have to prepare for the possibility that CO₂ removal (#CDR) doesn't work and #reduce #fossil #fuel CO₂ #emissions ASAP.
