Science is done by observation... Why not go out on a cloudy day and tell me that it's warmer than a sunny day.... because that is effectively what you are saying.
Korg.
No it's not. It's the NET effect ya muppet. If you had the cover during the day then removed it at night then the effect would be one of cooling and vice versa.

There have been studies that show they cause warning too though. You can find studies for both sides when it comes to contrails.
No they haven't admitted to that. The video that said they did was a deliberate misinterpretation. They were talking about the militaries use of chaff, and the claim was they said chemtrails
The U.S. government routinely conducts experiments on weather modification, and has been doing so for at least half a century. Previously classified under such names as “Project Cirrus” (1947) and “Project Popeye” (1966), weather modification is no longer a secret practice. In fact, a bill (S517) was sponsored in 2005 by Texas Sen. Kay Bailey Hutchinson, a Republican, “to establish the Weather Modification Operations and Research Board, and for other purposes.” This bill did not become law. Yet, there is reason to believe that various government institutions are carrying out numerous legal and illegal weather experiments without informing the public.
Even in the face of mountains of evidence, many people still believe that weather modification of any kind is only a fantasy. People must be aware that these technologies have been around for a long time, are indeed being used and have great potential for dangerous and unethical uses.
Project Scope
An ad hoc committee will conduct a technical evaluation of a limited number of proposed geoengineering techniques, including examples of both solar radiation management (SRM) and carbon dioxide removal (CDR) techniques, and comment generally on the potential impacts of deploying these technologies, including possible environmental, economic, and national security concerns.
The project has support from the National Academy of Sciences, the U.S. intelligence community, the National Oceanic and Atmospheric Administration, the National Aeronautics and Space Administration, and the Department of Engery(sic). The approximate start date for the project is March 2013; a report is expected be issued in fall 2014
Indeed, as we reported last year, a Harvard University project experiment funded by Microsoft founder Bill Gates saw thousands of tonnes of sulphur particles sprayed over New Mexico as part of a geoengineering study, despite the fact that even staunch environmentalists have warned the process could have catastrophic effects on the earth’s eco-system.
The planet is hot and getting hotter. But while most plans to use geoengineering to alter the weather have been rather hypothetical, now a pair of Harvard engineers have announced that they intend to spray thousands of tons of particles into the sky to block the sun's rays—within the coming year.

No one has denied that either. But it's a completely different thing to try to change the climate by spraying particles from planes to do it. You would need a massive fleet to do it, and no one has been able to find it. Fuel is routinely tested, and has to meet certain standards, if it didn't then it would be reported and destroyed, so it's not a fuel additive (not to mention what it would do to engines, and how expensive those are to replace so no way would the airlines go for that idea). It's not military, because they just don't have the planes to do it (both in type, and in ability to spray). So where are the planes?
Contrails do indeed exist... They dissipate and do not form cloud cover...

Why do you believe this to be correct information?
Korg Trinity
Only under certain conditions do Contrails expand into cloud cover... Please read further into the thread where this has been discussed.

How about you use some peer reviewed sicence when making your claims? Because if you keep just using your opinion and you keep being as wrong as you are, someone, somewhere will notice and you might end up moping the teachers lounge instead of whatever it is you think you do.
Seriously, learn some damn science. It's not something that "the big bad gubbament" has manipulated for their own evil purposes. It's what SCIENCE TEACHERS teach.
maybe going back to school would be a great start for someone such as yourself. At this time, you come across as a 21 year old kid who thinks he knows everything and refuses to accept reality.

No, the overall net effect of contrails (aka chemtrails) is warming.

Fossil fuel use, as well as producing greenhouse gases, creates other by-products. These by-products are also pollutants, such as sulphur dioxide, soot, and ash. These pollutants however, also change the properties of clouds.
Clouds are formed when water droplets are seeded by air-borne particles, such as pollen. Polluted air results in clouds with larger number of droplets than unpolluted clouds. This then makes those clouds more reflective. More of the sun’s heat and energy is therefore reflected back into space.
This reduction of heat reaching the earth is known as Global Dimming.
Global dimming is the gradual reduction in the amount of irradiance at the Earth's surface that was observed for several decades after the start of systematic measurements in the 1950s. The effect varies by location, but worldwide it was estimated to be a 4% reduction from 1960–1990. Since then, a very slight reversal in the overall trend has been observed.
It is thought to have been caused by an increase in particulates such as sulfate aerosols in the atmosphere. The switch from a "global dimming" trend to a "brightening" trend in 1990 happened just as global aerosol levels started to decline.
Global dimming has interfered with the hydrological cycle by reducing evaporation and may have reduced rainfall in some areas. Global dimming also creates a cooling effect that may have partially masked the effect of greenhouse gases on global warming.
Deliberate manipulation of this dimming effect is now being considered as a geoengineering technique to reduce the impact of global warming.

You're right, we need to start mass arrests now of people who fly. There were only 643 million people that flew in the US in 2011, so let's get right on it. That'll put a stop to those pesky contrails.
Or maybe we can go back to how it was in the 40s and 50s, and only the 1% can afford to fly, screw everyone else.
Funny, considering there aren't that many people in the US.
And if everyone flies twice on average, and a lot of foreigners fly into the USA??
And, the fact remains: people who fly are trusting their LIVES to a corporation.
Seems pretty stupid to me.
Yes...you do.

You don't understand. Korg makes the rules. Your silly "science" has no place in this thread.
This is the land of make believe. Now be gone with your "facts"!
When the atmosphere is supersaturated with respect to ice, the line-shaped contrails can spread to form cirrus cloud, which has a warming effect on climate.
We also computed the dependence of radiative forcing on the effective radius of cloud particles, the optical thickness of the cloud, and the cloud-top temperature (CTT) and determined that cooling effects occur with clouds when their optical thickness is greater than 4.0∼4.5

O.k I can see you are refusing to acknowledge or cannot understand what Global dimming is and what causes it...
