CHEMTRAILS%20-%20CONFIRMED%20-%202010%20by%20William%20Thomas

Most sightings take place far from navigation beacons and established air routes.
Nor do airliners obsessed with point A to B efficiency spend hours crisscrossing the same patch of sky
in close formation. To do so would violate many air safety regulations mandating minimum commercial
aircraft separation.
And passengers would refuse to fly in airliners without windows, as many photographs of the planes
show.
HOT AND COLD
Whether deploying contrails or chemtrails, tinkering with cloud cover could trigger unintended
consequences. Acting as a complex planetary thermostat, clouds cool the Earth by reflecting sunlight.
But they also heat the atmosphere by trapping outgoing heat.
“The net effect is a very delicate balance of cooling and warming,” a NASA scientist told the Rocky
Mountain News. “A small tip in one direction or another can eliminate global warming or greatly enhance
it.”
Both natural and aircraft-induced cloud decks can reflect sunlight that would otherwise warm the Earth’s
surface. Or they can act like an atmospheric blanket, trapping heat radiating up from the ground, instead
of allowing it to escape.
It turns out that contrails concentrated over regions of the United States and Europe have resulted in
local warming 35-times higher than the global average. [Christian Science Monitor July 29/97]
