contrails go away shortly after. chemtrails stay and spread almost creating there own clouds.

Contrails VS Chemtrails

Particulates and heavy metals are added to aircraft fuel which are then atomized into the atmosphere upon fuel combustion. It's why the California fires burned so hot and so fast... fire makes it's own wind currents in addition to those present. Testimony from seasoned firefighters reveal that they had never witnessed fires of this magnitude ever in their careers. Several mentioned that the Paradise area appeared to have been sprayed with fuel .......this is only one result of contrails........ take a deep breath...... you're breathing this stuff no matter where you live.....

Paradise Fire

The Paradise fire spread so rapidly do to that it needed to be select logged, called thinning to get rid of the dead wood, and by Santa Ana winds. I'v had the opportunity to talk to people from there that survived that inferno and they had asked for years why it wasn't being cleaned up and there voices were muted by environmental groups and the Govt. When you allow a forest to die due to disease and to many trees with out thinning and low water, and then combine that with, as the meteorologists and forest service people said, was the hottest and highest winds in decades, you have the perfect combination for a fire for the decades. Please educate yourself with facts and not just airplane rhetoric.

Chemtrails and rain

It was brought to my attention that chemtrails (geo-engineering) were present 3-5 days before a rain. I started watching. There could be no chemtrails for weeks and then there they were. I counted days and sure enough, within 4 days, they were followed by rain. What does that mean? Are they bringing rain? Are they an attempt to block rain? Is it a natural atmospheric phenomenon?

Chem Trails vs Contrails

I searched youtube there's lots out there about this - one biologist against geoengineering started crying during her presentation based on her concerns and another scientist for geoengineering is working on using sulfur by aerosol to deflect the sun rays being necessary because the earth is heating up at a rapid rate....not all scientists or politicians agree on the spraying. Al Gore a billionaire now, he discovered Climate Change in the early 90's. The most important topic today is "Climate Change". Google chem trails, all sites connected to Google are at the top; fact check, Wikipedia etc they shut it down as conspiracy theory by naming such as far right wing truthers, conspiracy theorists ...but actually it is no longer a conspiracy it's widely approved by certain scientists and political leaders - it is science and lobbying that determines action and outcome. San Francisco is painting their streets white... Will it fix things? Who knows. All you can do is write your leaders and congressmen with concerns because it's happening now.

Conspiracy garbage..

One that uses youtube as proof of something instead of peer reviewed studies is likely one you can say is a conspiracy moron.. if you knew what fact checking was you wouldn't be talking out of your ass about this shit here.. they got shutdown as conspiracy theory because that's exactly what they are.. it is NOT widely approved by scientists that's just your wishful thinking and conspiracy videos talking.

Global warming is a real thing. Chemtrails is a made up conspiracy.

Thank you - from a scientist

Reading these comments is absolutely horrifying. Science literacy needs to be taught as part of any science curriculum with the spread of information online. YouTube is not evidence; most politicians are not scientists & have minimal understanding of science; websites filled with opinion is not science. Research that has had to face scrutiny & criticism by other trained scientists is science, hence Bradley’s mention of peer-reviewed science. And those articles aren’t for everyone; this is perhaps how scientists have failed. We were comfortable telling people to just believe us as having some sort of superior intellect that we were caught sleeping at the wheel when mass disinformation came. Chemtrails are not real; we aren’t trying to manipulate human genetics or behavior through the use of aircraft (although that sounds like a great plot for an action movie).

Bradley, again, huge thank you on the mention of reviewed evidence versus public musings.

Chemtrails and the trogs who love them

Proof ?

Sunset Positions

The weather patterns on earth are changing and everyone around the world recognizes this fact. I've been keeping a close watch where the sun has set on 21 June, 21 September, 21 December and 21 March over the past four years. These 4 positions of the sunset
I've kept track of on a low mountain ridge approximately 5 miles west of my house in northwest Montana over the past four years. On 21 December 2017 I was very amazed to observe the position of the setting sun appeared to be a significant distance north of the fixed point where I had observed it setting on the previous two years before that date. I estimated the sunset position to be about 200 meters north of the point where I had observed it setting on 21 December 2016. On 21 March 2018 my observation of its setting point was similar. On 21 June 2018 the sun set too far north for myself to observe its setting position from my vantage point . On 21 September 2018 I noted its setting point north by a few hundred meters from where its setting position was on that date in 2016 and 2017. I know the wobble of the earth's axis is a natural phenomena could partly account for these shifts in sunset positions. However from my observations the rapid northerly shift of the position of the setting sun could tell us more change is on the way and could reflect in changing weather patterns among other things. I'll continue noting the shifting position of the setting sun for the remainder of time I'm on earth.

Sun Movement


I would love to hear your thoughts on the movement of the sun. Implications and I also wonder the ancestors what they may have foretold. Very stunning observations. Jeff
