Nothing i have studied can tell me how a vapor trail can continously grow and attract more ice particles, long after the plane has gone... can you tell me how it does it ?? Explain the reaction that is happening...
And please explain to me how this is not considered to be the foremost cause of climate change, the goddam temperature dropped 4 celsius and wind picked up. FROM ONE PLANE.

I have studied weather and observed for years, and myself along with everyone i know did not see them in my city till the last 15 years.
I know the engines have changed which may lead to "longer lasting fake clouds".

This is no doubt the most amazing fastest weather modifier out there, and yet it is NEVER talked about, kind of like they just dont EXIST.
Research suggests that fan use has no clear effect either way on hyperthermia.[10] A U.S. Centers for Disease Control and Prevention study published in the Journal of the American Medical Association advises that "although the use of fans may increase comfort at temperatures less than 90°F (less than 32.2°C), fans are not protective against heatstroke when temperatures reach greater than or equal to 90°F (greater than or equal to 32.2°C) and humidity exceeds 35%,"[10] and provides a similar but simpler warning to the public on their website.[11] These temperature and humidity conditions are consistent with summer weather in Korea, which is often very hot and humid. These temperature and humidity conditions are also consistent with a death cited in an earlier article critical of fan death, which suggested that fan use was irrelevant.
However, high levels of humidity do make air harder to breathe and are related to other problems that can cause asthma attacks.
According to Health Guidance, negative ions exist in the air that aid in the process of breathing. However, as the levels of humidity increase, the level of negative ions decrease. Furthermore, if asthma patients choose to purchase a humidifier to soothe their symptoms, they should look for ones that do not generate negative ions, because they attach to the water molecules from the machine and create positive ions that stifle breathing.
Higher levels of humidity cause higher levels of asthma-inducing agents. For example, when humidity levels go above 50%, the number of dust mites in the air increases. Furthermore, the American Academy of Allergy Asthma and Immunology found that high levels of humidity also tend to promote the growth of fungus and molds. Asthmatics' symptoms are bothered and heightened by the presence of these two agents.
Humidity
High humidity is also a cause of increased complaints of shortness of breath. There are a couple of possible explanations for this phenomenon. First, as humidity increases, the density of the air increases. More dense air
creates more resistance to airflow in the airway resulting in an increased work of breathing (i.e., more shortness of breath).
Another possible explanation is that as humidity increases, the prevalence of many known airborne allergens increases. Dust mites and molds both increase in high humidity.
Environmental conditions – especially humidity – can directly affect the functioning and performance of computers…
A high level of humidity can cause internal components of PCs to rust and degrade some of their essential properties, such as electrical resistance or thermal conductivity. Under extreme conditions, humidity can cause computers to short-circuit, resulting in effects ranging from loss of data to physical damage of some system components. This situation can be aggravated further when computers are in environments that are not climate controlled such as warehouses or areas on industrial floors where other chemical vapours may be mixing with the humidity and becoming corrosive.
Acid rain is a rain or any other form of precipitation that is unusually acidic, meaning that it possesses elevated levels of hydrogen ions (low pH). It can have harmful effects on plants, aquatic animals, and infrastructure through the process of wet deposition. Acid rain is caused by emissions of sulfur dioxide and nitrogen oxides which react with the water molecules in the atmosphere to produce acids. Governments have made efforts since the 1970s to reduce the release of sulfur dioxide into the atmosphere with positive results. Nitrogen oxides can also be produced naturally by lightning strikes and sulfur dioxide is produced by volcanic eruptions.

Drowning is death from asphyxia due to suffocation caused by a liquid entering the lungs and preventing the absorption of oxygen leading to cerebral hypoxia and myocardial infarction.[1]
Near drowning is the survival of a drowning event involving unconsciousness or water inhalation and can lead to serious secondary complications, including death, after the event.[1][2]
According to the World Health Organization, drowning is the 3rd leading cause of unintentional injury death worldwide, accounting for 7% of all injury related deaths (est. 388,000 deaths by drowning in 2004, excluding those due to natural disasters), with 96% of these deaths occurring in low- and middle-income countries.[3] In many countries, drowning is one of the leading causes of death for children under 12 years old. For example, in the United States, it is the second leading cause of death (after motor vehicle crashes) in children 12 and younger.[4] The rate of drowning in populations around the world varies widely according to their access to water, the climate and the national swimming culture.
When and Where People Drown?
Drownings happen year round and at all hours of the day and night. However, it is clear that drownings peak in the warmer seasons as people flock to the water for recreation and relief from the heat. Prime time for drownings is mid to late afternoon. Again, this is largely predictable given that this is the hottest part of the day. By late afternoon, after several hours of water recreation – and perhaps alcohol – people are generally more tired and less able to make good judgments about risk.
The vast majority of drownings occur in open water– the sea, lakes, ponds, rivers. However, drownings occur in all water including swimming pools and bathtubs. Small children have been known to drown in just a few inches of water – in buckets and ditches for example.
Water is a good solvent and is often referred to as the universal solvent. Substances that dissolve in water, e.g., salts, sugars, acids, alkalis, and some gases – especially oxygen, carbon dioxide (carbonation) are known as hydrophilic (water-loving) substances, while those that do not mix well with water (e.g., fats and oils), are known as hydrophobic (water-fearing) substances.
Depending on the temperature and the amount of moisture in the air at the aircraft altitude, contrails evaporate quickly (if the humidity is low) or persist and grow (if the humidity is high). Jet engine exhaust provides only a small portion of the water that forms ice in persistent contrails. Persistent contrails are mainly composed of water naturally present along the aircraft flight path.

WHY DOES MY CARS CHEM-TRAIL DISSAPEARE IN THE FROZEN NORTH???
Water is a chemical substance with the chemical formula H2O.
Do you get alerted when a chemtrail thread is posted ??
