In the three days that followed the 9/11 terrorist attacks, when all commercial flights above the continental US were suddenly suspended, a veil was lifted on the profound - though until that point unconfirmed - effects that aviation-associated artificial clouds are having on our planetary environment.
In the August 2002 edition of Nature, which is ranked the world's most cited interdisciplinary journal, a report was published titled "Contrails reduce daily temperature range," where scientists discuss how "a brief interval when the skies were clear of jets unmasked an effect on climate."
Three Days Without Contrails
The post-9/11 grounding of all commercial aircraft resulted in the sudden disappearance of condensation trails (contrails) from jet aircraft across the entire United States. According to the Nature study, the potential of contrails "...from jet aircraft to affect regional-scale surface temperatures has been debated for years...," but it was not until the three-day grounding period that doubts concerning the existence of the phenomenon could be put to rest.
The Phenomenon: A 1.8 Degree Celsius Increase In Temperature in North America
The study found "...an anomalous increase in the average diurnal temperature range (that is, the difference between the daytime maximum and night-time minimum temperatures) for the period 11-14 September 2001."
They go on to explain: "Because persisting contrails can reduce the transfer of both incoming solar and outgoing infrared radiation and so reduce the daily temperature range, we attribute at least a portion of this anomaly to the absence of contrails over this period."
They arrived at their measurements by analyzing maximum and minimum temperature data from approximately 4,000 weather stations through the conterminous United States (excluding Hawaii and Alaska) for the period 1971-2000, and compared them to the three-day post-9/11 grounding period.
They found an increase in the diurnal temperature range (DTR) of approximately 1.1 degree Celsius over normal 1971-2000 values, and an increase of 1.8 degrees during the grounding period in contrast to the adjacent three-day periods analyzed when DTR values were near or below the mean.
This is a highly significant finding as "The increase in DTR is larger than any during the 11-14 September period for the previous 30 years...," and since "...the 11-14 September increasing DTR was more than twice the national average for regions of the United States where contrail coverage has previously been reported to be most abundant (such as the Midwest, northeast and northwest regions)."
The study authors concluded
"Our findings indicate that the diurnal temperature range averaged across the United States was increased during the aircraft-grounded period, despite large variations in the amount of cloud associated with mobile weather systems. We argue that the absence of contrails was responsible for the difference between a period of above-normal but unremarkable DTR and the anomalous conditions that were recorded."
Discussion
First, it is important to point out that the observed post-9/11 elevation in temperature is not one-dimensional.
While clouds, including aviation-associated contrails may lower temperature by reflecting solar radiation off the planet in what is known as the "albedo" effect, they may also raise temperature by blanketing trapped heat preventing its nighttime radiative dissipation.
In fact, NASA's Earth Observatory states that "NASA scientists have found that cirrus clouds, formed by contrails from aircraft engine exhaust, are capable of increasing average surface temperatures enough to account for a warming trend in the United States that occurred between 1975 and 1994."The point, however, is that aviation-associated weather does profoundly affect temperature.
It is not necessary to believe in clandestine geoengineering programs, or malevolently dispensed chemical trails, in order to see the effect that modern day aviation is having – visibly -- on our skies. Billions of pounds of jet fuel are burned each year, adding a vast amount (albeit mostly invisible) of chemical pollution to our environment.
While the mainstream still considers the persistent condensation trails formed by jets to be a harmless and ephemeral, a growing sector of the public is increasingly concerned about the "chemtrails" they are seeing blanketing the sky – a term, in fact, which generates millions of searches and web page results through Google, but is equated with "conspiracy theory" via automatic redirection on sites like Wikipedia or Dictionary.com.
Considering the results of the Nature article, there can be little doubt that these trails are having a profound effect on weather right now, and such a profound one, that within just three days of their cessation, a massive temperature anomaly occurred over a surface area of 9,326,410 sq km, the land mass of the United States.
If, and that's a big IF, these temperature anomalies are a result of the absence of only jet exhaust, which we are told are "mostly water vapor," the unintended cloud-producing effects of commercial aviation taken in its totality is already (unintentionally) a global form of geoengineering qua effects. Simply viewing a satellite image (example above) of commercial jet paths reveals how artificial clouds are now overtaking natural ones.
Since the 1990s, climatologists like Jane Long and Julio Friedman have advocated cooling the Earth through solar radiation management (SRM), which proposes injecting sulfur dioxide into the stratosphere. The sulfur clouds would block sunlight, imitating the cooling effects of volcanos. Advocates suggest that geo-engineering is not only cost-effective, but also the only realistic solution to the problem of global warming.
However, other researchers are skeptical. A new documentary called Skywatcher: Contrails, Chemtrails and Artificial Clouds (public release 9-11-2012) offers a completely different perspective. The producer, Dave Dahl, asserts that we have missed the most important factor in climate change models: aircraft.
Climate modeling has started to include detailed studies of the effects of artificial clouds, which cool the ground during the daytime. Because of this, many people believe that covert SRM programs are already in full force. But clouds have a warming effect when they blanket the Earth at night, blocking the heat from escaping back into space. For this reason, clouds can cause overall warming, even though they bock sunlight during the daytime.
But according to Dahl, the immediate problem we face from climate change is global drying, not global warming, and our efforts to modify the weather with aircraft are toward the purpose of precipitation enhancement, not SRM. Furthermore, he asserts that artificial clouds created by aircraft are the cause of climate change, and our efforts to modify the weather are an aggravation, not a solution.
Governments worldwide are concerned about drought as the arid regions of the planet become even drier. But Dahl says today's precipitation enhancement programs are worsening the problem of climate change, and even in the best-case scenarios, we will not be able to meet our growing water needs through weather modification.
"I think it's this simple," said Dahl in an interview. "Clouds affect the weather and the climate. We are making artificial clouds. So yes, we are changing the climate, and this movie shows that clouds made by jets are accelerating these changes far more than the buildup of CO2 or methane, and are in fact the primary factor in anthropogenic climate change."

Pish tosh.
Keep paying those carbon taxes sheeple.
"It is not necessary to believe..."! What a tip-o'-the-iceberg that line is.
It won't be necessary to suspend ze dispelief as much in future, citizen - we have developed...shall we say less visible means of sky control. Now we will allow you to debate the past. Now you will need a telescope to see the dispensing mechanism. Ignore the ones in those mall bathrooms, that's just deodorant.
Here is a hint my friends, if an article uses the term persisting contrails, it's BS. That term is new and put out by NASA, there is no such thing. I'm not going to say much more than that, this is pure crap and those are not commercial airlines doing the chemtrails no matter what any computer desk-jockey has to say about it. I've been watching them make tornadoes and the like for 11 years and not once has one of those jets ever had a marking on them, not only that but I know where they land and they don't land at the airport people.
Anybody with a brain should realize by now the government is nothing but Bull and if you want to believe them fine, but don't tell others "thats a commercial jet" while it's falling out of the sky, doing circles, or climbing magically almost straight up, doing loop-de-loops and the like because you've never ridden an airlliner that has made a 1200 mile tic-tac-toe trip to make a 120 mile (as the crow flies, or should I say as an airlliner flies) trip, it just aint so.
And to any shilll who says they come from commercial airliners, show me the proof, show me the markings, all commercial airliners have numbers on them and chemtrail planes do not, enoough said. Not only that but I have mounds and mounds, make that millions of pictures from sattelite views showing 1000 mile long chemtrails up to 100 miles wide, bet nasa wouldn't comment on them though. And yes the computers auto-edit them out of the sattelite pix, but before they did I used to catch them boys celebrating christmas or the superbowl and not doing their jobs and wouldn't ya know it, no editing. I guess them dumb asses thought the whole world celebrated such stupid things, but not all and I caught them red handed, lines, lines, millions of lines everywhere across the globe, Oooops except over Iran and North Korea of course! What a crock of crap, never trust the media whores, and that includes Nature magazine or Popular Mechanics or any politician except Ron Paul, but don't expect Dr. Paul to know about such things, he is too busy trying to take the reigns from the Popes servants to study this.
Peace
yep when i first heard about chemtrails and witnessed them i went and did some research on contrails. The books i read stated contrails lasted only a few seconds generally and only lasted up to five to ten minutes very rarely in ideal conditions. Well the chemtrails are not contrails then.
I agree with the last two comments. I too have been watching these chem trails for a lot of years and have even watched them along the Pacific Coast preventing our normal rail fall for the winter months to come ashore. And look what that has done to the U.S. for this summer. Record breaking heat and drought in the Mid West where we grow most of the food this nation eats. I have even seen these lasting trails in movies and TV shows and also commercials. Some of these movies go back into the 1990's. Try finding, 'Blast From The Past', and at the end of the film they are filling the sky. I wondered when I saw that if it was done on purpose.
Now "Anonymous", we are working on North Korea and will have it under control soon. The goy Americans will fight another Korean war for us, you'll see.
In the meantime, we have sprayed everything else and are modifying the planet to suit ourselves, - which does not include you!
Global Dimming is the name of a PBS show that proved contrails effect global temp. During the 3 day period after 9/11 global temp went up 1 degree. Fortunately the temp. went back down when the skies over America filled back up with aircraft and their trails. This happened with the grounding of aircraft just over America. IMHO this means we are stuck with needing contrails just to keep us from literally cooking to death. Please note I didn't include chemtrails.
SEEEEEE, BETTER LET US KEEP SPRAYING OR YOU WILL ALL MELT! WE KNOW WHAT'S BEST. THERE ARE TOO MANY OF YOU BREATHING RIGHT NOW AND WE'RE BUSY TRYING TO SAVE ALL OF YOU(r money)...HEY! PAY NO ATTENTION TO THE EXTRA FOLIAGE. OR THE COOLING. OR HISTORICAL DATA. NOR THE SUN! side-effects may include: diminished view, increased cancer, carbon tax, HAARP attacks, heavy weather, sudden death, drought & famine, damaged planet, resource war, rotton core, Al Gore.
The temperature went up a few degrees for a few days. BFD. Then it went down again. BFD. The temperature will always go up and down a few degrees there Chicken Little. the general affect on the weather is more governed by ocean temperatures, which have trillions of times as much affect on air temperatures than any number of jets aloft or grounded. Tell Al 'D' Gore to give it up. 'Wizards' are so 11th century.(HINT: Heat capacity)
I believe that they are adding compounds to regular jet fuel as well as spraying with designated sprayers.
I got my pilots license when I was till a teenager and I was really into planes which meant that I CONSTANTLY watched the sky to try to identify the aircraft. I NEVER ONCE saw a contrail that crossed the whole sky. NEVER. These didn't start appearing till sometime in the 90s as far as I know. They are NOT regular contrails otherwise we would have seen them previously. Any explanations of it being due to certain "conditions" is bullshit, otherwise they would have been seen before.
