Global Warming temporarily reversed, on 911, when the air planes were grounded.

From an article I just looked at This article, the link that I put here on this discussion page at myLot today, is seemingly very significant because it points out how Vapor Trails at certain altitudes were reduced when air traffic was grounded in the US on 9.11.2001, Dark Tuesday, when the Twin Towers and Building 7 fell and all air traffic stopped over the next day or so. The effect of Layers of vapor trails or Contrails, also condensation trails, from commercial aircraft and private aircraft and also military, all contribute to trapping heat in at night, after sunset. The days following 9/11/2001, when air planes were not flying over a large area of the US, there was an apparent temporary drop in overall temperatures. The clouds we know as cirrus clouds become more dense when vapor trails or contrails form an especially over large cities where on normal days, when air traffic is at its regular levels of operation, the concentration of cirrus clouds mixed with vapor trails from commercial aircraft cause localized air temperature warming. Just something to think about while we go about our normal days of living.
Thousands of jets leave contrails over North America every day. They affect climate, but figuring out how was one of the more unlikely legacies of 9/11.

@lookatdesktop There is lots of little thing we can do and it all adds up. I've never liked driving and have a dodgy eye, anyway, so I use public transport when I can't use a bike. Thankfully cycling is increasing around here and I am not the only loony pedalling
