This is a fascinating piece of film that is being passed around at the moment. It shows movements of large aircraft (as yellow dots) over a 24 hour period, condensed down to 2 minutes. The amount of activity is quite astounding.
After 9/11, the USA grounded all aircraft flights in and out of their country. I have been told (though I can’t verify it) that this led to a measurable difference in the Earths temperature. The USA is one biggest users of aircraft and is of course receiving many flights from foreign countries. However, if a measurable difference can be made by just the USA alone banning flights, how much difference are we as a race making to our planet when you see all the flights from Europe, Asia etc that were not involved with the USA flight ban.
Then ask yourself, if that is aircraft alone, then what difference are all our cars, trains and industry making? Questions like that can make you go mad. Anyway, enjoy the film.

Hi Charlie,
there’s a transcript of a BBC documentary about the effect of jet-trails on climate at
