Giovanni, interesting to hear your experiences. I have a pet theory as to what else is going on – it’s aircraft exhaust. When the Iceland volcano erupted in 2010 halting aviation, the change I witnessed to my sky was dramatic and nearly instant. Normally there are so many aircraft leaving so many contrails. My record is 11 jets counted simultaneously from my garden. Back in the 1960s a British airline ran a TV advert – people in the street looking up at “the 8:50 Trident” spearing across the sky, glancing at their watches and seeing it was on time. If only we’d realised then that half a century on there would be an 8:50 and 10 seconds Trident, and an 8:50 and 20 seconds Trident, and an 8:50 and 30 seconds – you get the picture. It surely can’t go on at this intensity. Trust me, every wisp of cloud in this photo is artificial.
