The chemical society and its discontents: Ozone layer edition
The accidental #climate #scientist who uncovered an unexpected force of #globalwarming in the 1970s
"The young scientist had discovered that #chlorofluorocarbons - #CFCs - then widely used in the manufacture of refrigerators, air-conditioning units and spray cans, had a significant greenhouse effect."
“I was just a postdoc immigrant from India. I didn’t know if I should tell #NASA about this or not. I just sent the paper off,” Ramanathan recalled."

@swoop I still find it insulting to the physics to use precious heavy metals.just to boil water and make a turbine go brrr...
It's cheaper and overall better to invest in Renewables given that it'll be always easier, faster and more sustainable to install the same power in #renewables than #nuclear by virtue if being simpler!
Think CFCs were bad? Meet BFCs! But in the hands of my timeline, it makes for something more optimistic...and exotic.

Ozone recovery could trigger 40% more global warming than predicted | ScienceDaily…
As the #ozonelayer recovers, it’s also intensifying #globalwarming . Researchers predict that by 2050, ozone will rank just behind #carbondioxide as a driver of heating, offsetting many of the benefits from banning #CFCs [...] Source: Ozone recovery could trigger 40% more global warming than predicted | ScienceDaily

er #CFCS flyttet væk fra forsvarsministeriet og #FE?

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.
