PLANES PLANES,AND MORE PLANES

Only comment I have is that a whole lot of people are tired of our weather being done by these planes. Chemical trails they call it. A person has to be blind not to see it. It is all I hear all day,and all I see in the sky.

Now if all us little humans are not blind to this,why are you?

Barry's Response - Maybe someone lives in a no-fly zone or somewhere that is cloudy all the time...

Anyway, contrails, the elongated vapour trails left behind by aircraft, look like a serious pollution problem way up high in the troposphere. What you see is hot water vapour that has condensed (into steam) quickly after coming into contact with the cold air.

What else are those contrails? There's carbon dioxide, particulates (smoke), and trace amounts of products of incomplete combustion like uncombusted hydrocarbons, nitrogen oxides, carbon monoxide, and perhaps dioxins.

How do they affect the climate? After the September 11 attacks, no planes flew in the USA for 3 days. Data analysts found bigger changes in daily temperatures than usual during that period. There are also natural causes for that, so the project isn't conclusive.

Those trails left behind airplanes are occasionally called chemtrails.

There's a conspiracy theory that says aircraft's visible contrails aren't condensation trails, but rather chemical or biological agents deliberately sprayed for sinister purposes. There's no credible evidence to support the chemtrails conspiracy theory, and the scientific consensus rejects it.

Contrails, or condensation trails, are a natural byproduct of jet engines. At high altitudes, hot exhaust gases from aircraft condense into tiny ice crystals when they come in contact with the very cold air up there. Contrails are made up of water and don't contain any harmful chemicals or pose any health risks.

Despite its lack of scientific validity, the chemtrails conspiracy theory has gained some traction in certain online communities. There's a difference between genuine concerns about aviation's environmental impact, like greenhouse gas emissions, and unfounded conspiracy theories.

When people have concerns about aviation and its impact on the environment or public health, they should be based on true evidence and addressed through informed dissemination. It's essential to have informed, evidence-based discussions about aviation and its potential impact on the environment and human health.
