The BS about ice crystals lasting for hours, suspended in the atmosphere, is just that.
L I did NOT watch the video so what I am saying may be out of context, but there are a lot of ice crystals floating about in the atmosphere.
I often hear and see it said that contrails do not persist in the atmosphere, they dissipate right away. Supposedly only chemtrails last. I would take contrails lasting longer as a sign of climate change before I believe it was chemtrails. this is not to say chemtrails don't exist though I'm still up in the air on that one. The upper atmosphere is cooling and this would cause ice crystals to persist longer than has been noted in previous decades.
Allied bombing raids leaving from Britain seem to have affected the local climatic conditions. Rob MacKenzie, now at the University of Birmingham, and Roger Timmis of the British Environment Agency looked at weather records from 1943 to 1945 and found that after massive air raids the areas the planes flew over were cooler than similar areas nearby. Discovery News recently wrote about how modern planes affect the weather. The white vapor trail left by an airplane, called a contrail, can cause weather changes. The contrails form when hot, particulate-filled airplane exhaust blasts into the cold air of the upper atmosphere, in a layer called the troposphere. Sometimes the contrails simply fade away, but they can also become seeds for larger cirrus clouds. The thin, wispy cirrus clouds block some of the sun's rays, causing the shaded area underneath to be cooler. "Witnesses to the huge bombing formations recall that the sky was turned white by aircraft contrails," said MacKenzie in a Wiley-Blackwell press release. "It was apparent to us that the Allied bombing of WW2 represented an inadvertent environmental experiment on the ability of aircraft contrails to affect the energy coming into and out of the Earth at that location," MacKenzie said. By looking at World War Two records, the researchers were able to look at a time when commercial and civilian air traffic was rare. In East Anglia, the Midlands and the West Country, where many of the bombing raids were launched, there were almost no other airplanes. In 1943 the United States began basing bombing raids out of England, and there was a tremendous increase in the amount of air traffic in specific and well recorded areas. That made distinguishing airplane-influenced climate data more clearly discernible from unaffected nearby climatic conditions. For example, on May 11, 1944, a massive number of planes flew through an otherwise clear sky in south east England. A total of 1444 aircraft were recorded. The area they flew over stayed an average .8 degrees Celsius (1.44 degrees F) cooler than surrounding areas from about 7 a.m. to 1 p.m. "This is tantalising evidence that Second World War bombing raids can be used to help us understand processes affecting contemporary climate," concluded MacKenzie. "By looking back at a time when aviation took place almost entirely in concentrated batches for military purposes, it is easier to separate the aircraft-induced factors from all the other things that affect climate." http://news.discovery.com/earth/ww2-air-raids-affected-the-weather-110710.html
