Ummm, it has been talked about ad nauseam, so lets bring it up again for the millionth time. While we are at it, Newark always seems warm doesn't it? Has that ever been discussed?
I never heard this one either over the years. So you are saying that as we warm up a bit, colder departures will be larger with the new norms. That is mind blowing stuff. Any links to papers on it? Fascinating.
