You know....if I were to believe any part of the grand “cabon issue”....this would be the one thing that I’d connect to it and say it has potential. The interesting thing is that prior to the early 1970s....the vast public didn’t travel by jet. Only when discount airlines appeared and the prices went down in cost....did the public jump on and ride in abundance.

But here is the thing....if we ever did come to believe in this as the major contributor....the only answer (NOT taxes, trust me)....is to simply cut off jet travel. Either you go by boat, blimp, car or train to wherever you want. Airports would die off quickly and bankrupt a huge portion of America. The airline industry would dissolve away completely.

So I’m open to this if Al Gore wants to make this the “cause”. But for some funny reason, I don’t think he will. It really doesn’t help his agenda...stealing from the rich and middle-class.

This before factoring in the Chemtrail phenomenon.

[Cyclops08]

chem trails are the province of trailer park pseudo science.

Butterfly farts are far more dangerous than airplane contrails.

I thought everyone knew this.

[ElkGroveDan]

Sure if cow farts can, anything can.

[TigersEye]

Amazing! Scientists say a super volcano eruption, a thousand times bigger than the Mt. St. Helens blast, would give us a few years of volcanic winter but it wouldn’t change the climate long term. But vapor trails and car exhaust would. Truly amazing!

[Seven plus One]

Jet contrails only persist when the atmosphere at that altitude is near saturation anyway. A general blanket of cirrostratus coming in would not be unlikely anyway. The article says ‘scientists have suggested’, not ‘science has proved’. Suggestions are cheap on this topic.

Thanks for posting this. It removes the excuse of “this makes FR look bad” from the trolls on the CertifiGate threads.

"Can aircraft trails affect climate?"

Definitly. Talk to an AC-130 gunship fire-control guy. You need shovels and barrels to empty out the spent 20mm and 150mm howitzer shells. They blow off really fast. Water-cooled gun barrels.

And don't forget the flares they launch also before going in. Afghan could be warmer with white phosphourus rounds from those 20mm guns. Everything burns down fast.

Travis maintains that contrails are an important factor in climate change. "Eventually these impacts will be felt," he says.

He just needs another grant or two and he will be able to prove it. Really. /s

I feel dumber for having read this.

Climate change and its effects on ecology, socioeconomics and policy. I’m new at NRCC as of November 2007 but have been a copyeditor for NPG since 2005. Before that, I studied molecular and marine biology [no mention of a degree](with a dash of the history and sociology of science), taught English in Slovakia, and edutained children in nonprofit theatre projects.

Another "educated scientist" brings up any old theory to further the global warming lie.

I wonder how she "edutained" children about global warming?

How many tons of fuel do airline dump per year it may have a part in a change???.

Beam me to Planet Gore !

Simple test: have the weather "experts" produce plots of any and all measured variables all across the nation and across the date range of, say, 1995 - 2005 -- but with no date-range scale indicated. (i.e a truly "blind" test....)

Then, invite any and all to attempt to locate a three-day timespan within that data that appears to be "anomalous".

If the three flight-free days are truly "anomalous", a "consensus" should form -- focused on those dates.

~~~~~~~~~~

My guess is that there will be hundreds of three-day spans that are "stranger" than those three days -- if the data is examined by those who are looking at "the big picture", rather than trying to find something odd about those specific three days.

Bottom line: the "three-day 'witch hunt'" approach used in the cited "scientific" study virtually guaranteed that the search would continue until something anomalous about those three days was found. That is not only lousy science, it is intellectual dishonesty.

Dimming the Sun

[JustDoItAlways]

If the contrails are “White”, does that not mean they are also reflecting light photons back to the ground as well as reflecting incoming sunlight.

This study would need to measure the incoming EM radiation blocked/reflected back to space as well the outgoing EM radiation blocked/reflected back to the ground.
