Chemical Trails theory
The government mindlessly flies big jet airplanes over my area constantly from a local Air Force Base for no apparent reason I do believe that they are unmanned drones. If the CO2 accumulation in the atmosphere is becoming a problem then why do they continue to mindlessly fly these big airplanes in the sky constantly all the time even at night. Chemtrails are not made up by people who wear tinfoil hats the proof is the truth and that they do spray this skies with different products including aerosols and sulfur dioxide temporary block out the sunlight to cool the planet. There are currently a lot of inventions being promoted to reduce the Greenhouse Effect and some of them are not logical some of them are. The way it is is very expensive yet we cannot temporarily cool down the planet not knowing the feedback loop of what will happen after the cooling subsides and we have a runaway greenhouse effect. Yes the Earth does change naturally though no time ever recorded have we ever burned so many fossil fuels that the accumulation of methane CO2 and other nitrous oxides and such are at an alarming rate due to the industrial population explosion. When volcanoes erupt they emit a lot of different stuff such as sulfur dioxide which temporarily does create a Ice Age if it is a big enough eruption to block the sunlight out for days, weeks, months and even years. The 1% of people who have more money than all of the 99% are the ones behind trying to fix the climate crisis that we are currently producing man-made climate change.
Chem trails theory
Why do people continue to to the wrong thing......GREED BASED PERSONAL PREFRENCES. The same reason why industries have been moved overseas and poverty and incarceration has increased here in the US. Greedy people push for business as usual to maintain profits and don’t care about environmental or social impact. Why would anyone think that the government would do the right thing?

The prediction for Weather Conditions during the period of Feb 5-13th didn't age well.
Dictionary
The dictionary says this for contrails: a trail of condensed water from an aircraft or rocket at high altitude, seen as a white streak against the sky.
The dictionary says this for chemtrails: a visible trail left in the sky by an aircraft and believed by some to consist of chemical or biological agents released as part of a covert operation.
Chemtrails
Chemtrails are a conspiracy theory made up by tinfoil hat wearing plebs. The same people who believe in ' crisis actors ' and lizard people.
Global warming or climate change.
Justin is right. It is a ruse for globalists and environmentalists to scare people into a government where what "they"says goes. What a crock!!
Under-informed
Justin, like 99% of the population, you are under-informed. You have some catching up to do, quite a bit in fact.
Contrails myth proof…
Watch the wings of any race car in cold weather, especially with Indy cars or big wing sprint cars. You can see a vapor trail coming off the wings (or spoilers) when cold air is compressed against the wing panels as the race car enters a turn. In dragsters the vapor trail is due to the extreme angle of the wing in relation to the impact of the air at which point it heats up. Once this warmed air mixes with the colder & less dense air a vapor is created.
correction
Vapor trails are the opposite. Wings and plates cause the air moving across them to accelerate, with causes a drop in static pressure and corresponding DROP in temperature. Moisture in the air moving across those fins /wings/plates then condenses into visible "vapor trails" (fog). Acceleration is highest at the edges and corners. It is most likely to be seen when the outside air temperature is warm, not cold because warm air holds more water vapor that can condenses to fog when cooled -- Aeronatical engineer
Contrails.
It all comes down to you folks. Don’t like contrails don’t fly. Don’t like global warming don’t drive,don’t heat your house,don’t use any electricity at all, don’t buy anything that has to be delivered. You think that won’t cause livability problems? It’s in everyone’s hands. Cold turkey or keep to yourself.
