Gazing up at the Full Moon this evening in Central London, I noticed the strong corona as light, high clouds wafted across its face.
Later in Outer London, I looked up again, and saw the Moon Ring was wider, and perhaps more brown.
I saw a man eating an apple on the train platform who also looked up.
“It’s going to be a cold night tonight”, I ventured, “there’s ice clouds around the moon.”
“It’s not ice”, he intimated, “…it’s the gases….”
An exceptionally chilly English October, and yet still the Earth is heating up, on average :-
