Scientists at Harvard (David Keith) have decided that global warming is an emergency and something has to be done to slow it down. They proposed spraying particles into the atmosphere that would reflect some sunlight, simulating the effect of a volcano. And they announced recently they would begin experimenting.
Conspiracy theory websites have been talking about chemtrails for years. These are, supposedly, particles sprayed by jet planes. The purpose is to slow global warming, control weather, population control, anything evil you can imagine.
After I heard about chemtrails, in 2013, I started observing the sky. And I have often seen them covering the sky, looking as if they were intended to block the sun. I have also seen a blackish haze covering the sky when there are no clouds.
Now, of course, anyone who says they believe in chemtrails is immediately labeled a nutty conspiracy theorist and ignored.
I do think the chemtrail conspiracy theories are nuts. But I also know that spraying particles is a serious proposal, which they are now experimenting with. And I also know that I have been observing chemtrails for 6 years.
There are various ideas and theories about what kind of particles to use. Some are more scary than others.
