Pretty. But #nacreous #clouds are also destroying the #ozone layer: https://www.dw.com/en/our-beautiful-planet-the-dark-side-of-mother-of-pearl-clouds/a-47324081
"The ice crystals in the clouds spur on a chemical reaction between the ozone layer and gases such as bromine and chlorine. According to the US' Environmental Protection Agency (EPA), just one atom of chlorine in the #stratosphere can destroy more than 100,000 ozone molecules.

Without nacreous clouds, these destructive reactions would be negligible."

I saw this cloud at sunrise this morning looking East in Edinburgh. it lasted ten minutes #motherofpearl #nacreous #weather #Scotland #Edinburgh #cloud

Not every day that I cycle out of Waverley station and see the #stratosphere lit up in the dawn sky. Not as big a display of #nacreous clouds as 2016 (https://blogs.ed.ac.uk/hughpumphrey/2016/02/02/nacreous clouds/…). It faded quickly as I rode to work and was gone by I reached Kings Buildings.

Tá sé deacair grianghraf ceart a ghlacadh le mo ghuthán ach thaispeáin muid don bhus scoile é agus áthas ar na páistí go léir iad a fheiscint. Cuma ola ag glioscarnacht sa spéir orthu. #Gaeilge #grianghraifeanna
