"The surge in megasatellite constellations is creating problems beyond amplifying the Earth-circling space debris, according to new research. Reentering spacecraft and rocket stages may also be damaging Earth’s atmosphere. 'Space waste,' spacecraft reentering the atmosphere, injects a considerable amount of its matter into the mesosphere and lower #thermosphere — enough to potentially weaken the Earth’s #ozone layer."

“In general, from 2020 onward, a strong rise in space waste mass influx to the #atmosphere can be seen. ... This indicates a substantial risk of long-term adverse effects on the atmosphere such as #ozone depletion, radiative effects and changes in #cloud formation, if no action is taken. Research is urgently needed into the atmospheric accumulation, #chemistry, and general atmospheric effects of specific elements.”

Today is a good day. Today is the birthday of the Montréal Protocol.

Adopted on September 16, 1987, and ratified by every UN-member state, this landmark treaty stands as the shining example of what humans can achieve when science, diplomacy, and collective action unite for our common good.

A mere 10-15 years after researchers had come to a consensus that chlorofluorocarbons (CFCs) were the cause of an expanding hole in the #ozone layer, international diplomacy defeated corporate interests in a battle for our future.

CFC emissions were reduced and eventually banned. The result of the Protocol is an ozone layer hole recovering, no longer expanding.

But aside from the tangible outcome, this day is about what the Montréal Protocol represents: facing uncomfortable truths, recognising the urgency, setting selfish interests aside in the pursuit of shared interests.

It’s #solidarity. We did it once, we can do it again.

Enjoy your #MontrealProtocol day, everyone.
