Aircraft vapour trails 'could cause global warming'

Actually, the contrails have nothing to do with global warming. They have everything to do with mind control and the sapping of our precious body fluids.

He always seemed to have an excess of post-digestive gas and would give it up freely.

Great post, BK. I wonder if these folks have considered that should their wishes come true, there will be no one to fetch their lattes?

SOMEONE CALL ART BELL!!!!

Art already thinks vapor trails are "chem trails".

"Somebody" (Lockheed, Alcoa or the like) has a patent on adding aluminum to jet fuel, which supposedly reflects the
Sun's rays and alleviates some of the global warming.

I think he was also claiming the idea goes back to Edward Teller.

The "chem trails" are also used for nefarious purposes too...

The exhaust plumes contain carbon dioxide and chemicals which can lead to the production of ozone

Since the enviros are also worried about ozone depletion over Antarctica the solution is obvious - require every flight to take the southern polar route. Ozone is generated, the hole is filled, Gaia will smile upon us, and we can all burst into a chorus of I'd Like to Teach the World to Sing.

True. And you know about wind, right? Wind is caused by all o' them trees swaying back and forth. Check it out for yoursel; if the trees don't sway I can guarantee you won't get any wind.

Pseudo-scientist rant off

Dr Minnis found that as air traffic in the US rose by more than 500% from 1970 to 1995, the number of cirrus clouds in the sky also increased.

Until now scientists have been unable to say whether they increased for natural reasons or because of aircraft.

According to the Minnis study the conditions needed to create natural cirrus clouds did not become more common from the 1970s to the 1990s.

He concluded, therefore, that aeroplane vapour trails – also known as contrails – which are clouds of ice crystals mixed with exhaust gases, must be responsible.

For the love of Pete. Well, at least it's a good example of how NOT to do science.

They don't lend themselves very well to the reality of Westerns either.

IIRC, there was an episode of "The Big Valley" sometime abt. 1968 where "Buck", "Heath", and "Victoria" were standing at a fence with a long, faint contrail crossing behind them in the distant sky.

THE CHEMTRAILS ARE CAUSING GLOBAL WARMING! (lol)

Pick up a copy of "The Cooling," by Lowell Ponte, 1976. Its out of print but Amazon has 30 used copies available at $3.75. It makes for a good laff and would make a great gift to a Liberal friend.

The exhaust plumes contain carbon dioxide and chemicals which can lead to the production of ozone – which creates smog.

First the greenies complain about the destruction of ozone, forcing a ban of all CFCs, despite the fact that doing so resulted in great losses to the economy, potential losses to human life (e.g., halon-based aircraft fire suppression systems), and losses to the environment itself (replacement refrigerants, for example, are less efficient thus requiring more energy use).

Now they are complaining about the creation of ozone.

Well, which is it? You can't have it both ways.

[John H K]

Sorry, it's perfectly valid science. They did a study of the days after 9/11, based on archived sat pics, and the cirrus cover was much, much lower than the current "normal."

It's blatantly obvious to anyone who spends any amount of looking at the sky that contrails cause cirrus clouds.

[joesnuffy]

no no no not aluminum - barium

[John H K]

Yes, you CAN have it both ways.

Ozone in the stratosphere is good.

Ozone in the troposphere (everything lower than the stratosphere) is bad.

Not complicated, pretty well understood by science.

[Redcloak]

A beef and bean burrito is a more likely cause of global warming.

[azhenfud]

"It's blatantly obvious to anyone who spends any amount of looking at the sky that contrails cause cirrus clouds."

And how about the planes that don't leave contrails? Do they cause clear skies?? ;-)

[clamper1797]

I would have guessed that most of the global warming was caused by the hot air belched out by junk scientists

[dfwgator]

So what? Man is part of the environment, deal with it!

I suspect that eradicating smallpox was wrong. It played an important part in balancing ecosystems. —John Davis, editor of Earth First! Journal

Oh, that's a particularly good one. I woner how the Leftists would feel if that statement was "tweaked" slightly:

I suspect that attempting to eradicate AIDS is wrong. It plays an important part in balancing ecosystems.
