Here is what it most likely is, just found the link:
Is the U.S. creating cloud cover?
Believers contend feds behind 'global dimming'
Idaho State Journal | September 28, 2005
They call it Project Cloverleaf. At night, giant
planes with no pilots roam the sky over the U.S.
Instead of a mere vapor trail, they are filling the
sky with unknown chemicals designed to darken the earth.
To thousands of people around the U.S., this is not a
sci-fi movie or even a conspiracy theory; it is real.
Scott Stevens is a believer.
Stevens, a meteorologist and weatherman with News
Channel 6 in Pocatello, said the phenomenon known as
"global dimming" could be a clandestine operation by
the government to slow the effects of global warming.
While global dimming is a contentious scientific
issue, some scientists think thicker cloud cover may
be reducing the amount of sunlight reaching the earth.
Stevens, who also runs the Web site
www.weatherwars.info, said he believes the cloud cover
is generated by airplanes with chemical substances in
their fuel to increase and extend the effects of vapor
trails. Stevens has appeared on several national radio
shows, including "Coast to Coast AM," in an effort to
educate the public about chemtrails.

"It's called 'Project Cloverleaf' and it is the
primary reason the U.S. has not signed the Kyoto
accord, because we already launched a program to try
to counteract the CO2 problem and the methane
problem," Stevens said. "And that is through
distribution of aerosol."
Science has established that vapor trails left by jets
can form into clouds, actually growing and spreading.
Some scientists think vapor trails might be part of a
decrease in sunlight reaching the earth, but they do
not believe Project Cloverleaf exists.
While scientists may be skeptical, people around the
world have latched onto the unconventional idea. A
Google search of "project cloverleaf" brings up about
50,000 hits, many of them conspiracy theory Web sites.
A search of "chemtrail" gets about 280,000 hits.
Stevens said it is perfectly logical that jets would
produce contrails and said it would be unusual if they
did not.
"The question is persistence," he said. "What happens
is eight days out of ten, conditions are favorable so
that when a plane flies, the contrails persist. I
would guess that normal is closer to 3.5 to five days.
That means a rough guess is that there is a doubling
in the number of days where these contrails can last."
Stevens said many different types of aircraft are
spreading the aerosol as part of Project Cloverleaf.
"I think you have the whole range. I think you have
some aircraft that have clean fuel. I think you have
some aircraft that have some additive within the fuel
to create additional cloud cover," Stevens said. "And
then you have the black ops planes, and that is all
they do. There is the regular condensation trail, and
then everything else is for the delivery of aerosols."
Patrick Minnus, a senior research scientist at NASA's
Langley Research Center, said that contrails currently
account for roughly 3 percent of the cloud cover over
the U.S.
Minnus said cloud cover generated by airplanes
increased by about 3 percent between 1971 and 1995,
but he attributed the increase to additional air
traffic, not to a clandestine operation by the
government.
"I don't understand it," Minnus said. "Its just one of
those conspiracy theories. No amount of logic can
debunk it."
The theory may have been hatched after Minnus, David
Young and Donald Garber, all researchers and NASA's
Langley research center, presented a paper called
"Transformation of Contrails into Cirrus during
Subsonic Clouds and Contrails Effects Special Study,"
Minnus said.
In the study, the researchers used a DC-8 airplane to
fly an oval pattern off the coast of Texas.
"We just watched the contrail blossom and turn into a
huge cirrus cloud," Minnus said.
When they presented the paper in 1998, the Project
Cloverleaf theory began to spring up, he said, adding
that he did not know if it was coincidence or not.
Minnus said that contrails are formed in air below -39
Celsius when the air is supersaturated with ice.
Due to the physical structure of ice, the humidity
level actually has to be higher, about 150 percent
humidity level, than it would be for the air to be
supersaturated with water.
"The exhaust (jet engine) injects a lot of water into
the air," Minnus said.
"The water droplets immediately freeze and you wind up
with a contrail."
Minnus said once the contrail is formed in
supersaturated air, larger ice particles become nuclei
and begin to grow, collecting other ice particles from
the surrounding air.
As the particles get heavier, they begin to fall out
of the contrail, spreading it vertically, wind shear
spreads the contrail horizontally as it continues to
collect ice from the atmosphere.
Minnus said in a 1998 paper called "Spreading and
Growth of Contrails in a Sheared Environment," that
aged contrails can form into clouds almost
unidentifiable from natural cirrus clouds.
"Since these persistent contrails have long lifetimes
and grow to cover large areas, they have the greatest
potential for affecting regional or global climate,"
Minnus said in the paper.
Stevens' idea of weather modification by the
government may seem far-fetched to climate scientists.
But other scientists have considered airplane
contrails as a means of counteracting global warming.
A paper published by the National Academy of Sciences
in 1992, "Policy Implications of Greenhouse Warming:
Mitigation, Adaptation, and the Science Base,"
speculates that commercial airliners could use
contrails or spread dust to combat global warming.
In the geoengineering section of the study (p.459),
the paper states, "Cloud stimulation by provision of
cloud condensation nuclei appears to be a feasible and
low-cost option capable of being used to mitigate any
quantity of CO2 equivalent per year."
The paper also says, "These possibilities appear
feasible, economical and capable of mitigating the
effect of as much CO2 equivalent per year as we care
to pay for ... Such systems could probably be put into
full effect within a year or two of a decision to do
so, and mitigation effects would begin immediately."
Ellsworth Dutton, an NOAA research meteorologist based
in Boulder, Colorado, said there is not only no
Project Cloverleaf, there is no global dimming.
"The last published data set that showed a downward
trend (in solar radiation reaching the earth's
surface) was published in 1990," he said.
Dutton said there was a curious decrease in service
radiation during the 1970s and 1980s but that trend
appeared to have ended.
Stevens says global dimming is not only occurring, but
is having an effect.
"We have seen a real result because we have not seen
the warming that should have accompanied the increased
output from the sun, carbon dioxide, the methane. We
have not seen the evaporation off the oceans that
should have accompanied the warmth."
Stevens has no doubt about the feasibility of keeping
the general population in the dark while operation a
huge weather manipulation project.
"There is nothing that isn't possible. The only thing
that gets in your way is your will. If you have
thousands of scientists, an unlimited budget and
political powers telling you to do something, it gets
done," Stevens said, adding that people need to be
alert to changes.
"There have been some manipulations of the environment
for a rather lengthy period of time. We are coming up
on thirty years that weather engineering has been
attempted, if not accomplished. It is indeed within
forty years where we begin to see this slope of
warming accelerating," Stevens said. "How much of that
is mankind and how much is natural?"
