You are not listening to the Scientists in this. You are
listening to those that don't know about it. I can come up with
tons of fantasies why it happened but the fact the temp raised by
3 degrees during the exact days that the Aircraft were grounded
and no other explanation can be found. Cause and effect. You
can't change physics.

Now, I have used scientific information why it happened. Now it's
your turn. Since it's not normal, you need to present your own
proof so I can view it.

So, you claim to have PROVEN that "jet pollution" causes global
COOLING, because LACK of "jet pollution" caused an almost-immediate
3 degree rise in global air temperatures.

So why is it that so many so-called environmentalists keep claiming
that same pollution causes "global warming"? How is it that you
can so handily prove them wrong?!?

Anytime you cover a section of sky with something, it refracts the
rays of the sun back into space. It's so simple, try and keep up.
When you remove that barrier it will cause a temperature increase.
Most of what the Jet Engines leave is water vapor and that is the
same as a cloud cover. According to some, you should be cooler in
the sunlight than when a cloud cover comes over you, right?

Uh, no...

You just showed how "scientific" your analysis is [NOT] by showing us
you don't know the difference between refraction and reflection. You
also totally dismiss any absorption and reradiation of heat or any
other interactions.

So, you have just proven you have absolutely NO IDEA of what net
effect, IF ANY, a contrail may have!

Ask the experts then: "Researchers: Contrails Add More To Global
Warming Than Airplane Emissions"
Mar 30, 2011 – "In a new paper, scientists say the condensation trails
left behind by aircraft could be causing more climate warming than the
CO2 emitted by all aircraft since the start of aviation".

Actually, the exact opposite occurred right after 911. The Lack
of those contrails allowed an average temp increase of 3 degrees
across the United States and Canada. The long run might be an

As I recall the Daytime average temps were warmer and the nights were
cooler, so it averaged out close to a net zero. .

increase but the short run (when they are abruptly missing)
causes a temp increase. After the flights were resumed, the temp
went back to normal.

We'll probably see a lot less air traffic(and driving in general) in
10 to 15 years when peak oil drives the price of fossil fuels to
painful levels.
