And I bet that the month of September has the most number of cloudless days across the Notheast than any other time of the year with or witout contrails. Shut down all flights in January or February, and I bet the Northeast is still covered by clouds most days. How much you want to bet this wenie compared September of 2001 post 9-11 with February of 2002.
This stuff is bunk from the get go.
Actually, you are not recognizing the high-altitude nature of these contrails, as opposed to the low-hanging winter stuff that blankets a lot of the eastern seaboard and midwest of the U.S. during winter...and Seattle year-round--allegedly! :-) [ Actually, not true, just a scam by Washingtonians to keep California people out! ]
Anyways, this possible connection has not been previously advanced by the enviro wackos...but by the most solid of meteorological researchers who have been debunking the junk science of the global warming religionists. And it was proffered because of the NASA satellite data showing distinctly impacted variations in temperatures at various layers...as the more reasonable hypothesis than the knee-jerk CO-2 conjecture...which did not fit the facts at all.
