What's in those fake clouds they make to prevent global warming, and is it healthy to breathe?

Question

Just last tuesday, the national weather service said there would be "increasing clouds during the mornings, with chance of rain in the afternoon from thursday to sunday". Then, about 6AM thursday morning, I noticed jet airplanes leaving long white lines, short white lines, and curved white lines, almost like they were fingerpainting in the sky. By afternoon, the lines had spread out like big whispy feathers, filling the sky, and on the horizon, you could see (in the desert where I live, 100mile visibility is common) the "clouds" settling to the earth in a sort of haze, enveloping everything. Though I could not see it up close (the particles must be too small) I knew i was breathing whatever it was the planes used to "fingerpaint the sky" in the morning. What is that stuff, and is it like, vitamins or something? If it were bad for you, the government wouldn't allow them to spray us like the med-fly, would they?

Answer 1

those are chemtrails..

no,  they're not so good for you.

Answer 2

o_O I have no Idea what you are talking about....

The Real Thing is just salt water particles from the Ocean, it's to make them, the clouds, more reflective, so that light/heat from sunlight is bounced back into space, thus cooling the earth.

they will use Ships, not Planes, to do this.

Answer 3

That's called a vapor trail, it's made when the exhaust of the fuel is dispelled and the moisture in the exhaust condenses.  I'm surprised that you haven't noticed them long ago....

You see the same thing coming out of the back of a car on a cold day.
