First, we have to agree on what we all see in the skies.
Everyone in the world sees the trails coming from ordinary engines, attached to ordinary airliners, on ordinary flights.
There are millions of photos on the internet.
All trails contain the same chemicals, because those chemicals are present in the fuel.
Every contrail-induced cirrus cloud contains chemicals; therefore, all trails are chemtrails. No trail from any commercial airliner is without chemicals.
They all use Jet A1 fuel, which has a high number of elements that create small ice nuclei when burnt through the engines.
These small ice nuclei coated in sulfur make the trails grow faster in subsaturated air (clear blue skies).
The skies are not the same as they were decades ago, and it is not because more people fly now.
The criss-cross patterns in the sky are commonplace, and we see them almost every day.
We all know that without the chemtrails, it would be a clear blue sky, with lots of sunshine.
We all see them spoil our weather most days.
The day starts off with a lovely, clear blue sky and ends up very quickly being taken over by a mass of white criss-cross lines that do not dissipate.
Instead, each one lasts for many hours. Often, they spread out to cover a massive area of the sky. Very quickly, every bit of blue sky is turned into white cloud cover.
We all see the same thing, almost every day. It spoils our weather and changes the way we see our day.
Everyone is always in a better mood when the sun is shining.
So what is happening to our skies?
