Vapour In The Sky

It's unseasonably warm for November. 15 degrees Celsius today. This time last year we were up to our armpits in the cold white stuff.
I love sunny winter days. Cheers me up and today was a day for being cheered.
I have heard that all the contrails in the sky left my the numerous jets criss-crossing the world are leading to global darkening and contributing to global warning. I just think it looks pretty.
