First of all, the field of geoengineering is an academic fact. See https://duckduckgo.com/?q=harvard+university+geoengineering+program&hps=1&atb=v327-1&ia=web and https://duckduckgo.com/?q=geoengineering+program&atb=v327-1&ia=web.
I have seen this activity in different places where I’ve lived–often.
We should just look up and ask questions, but we are trained by the system from an early age to think that someone is looking after us. We follow what the media tells us to think about. An modern proponent of this was Edward Bernays. See Propaganda.
Geoengineering is part of the overall agenda.
There might be exceptions in which someone is merely trying to make rain or snow for ski hills etc., but otherwise, generally speaking, it’s all bad–one of the most horrific things that is happening, likely affecting the soil, ourselves, everything underneath, not just the weather.
I do not remember anything like this from the 1980s. I saw more blue skies.
People will often insist on mixing them up with memories of contrails–which are short and short-lived–and with airshow smoke trails.
There have been reports from people who are able to accept unpleasant realities since the late 1990s, Alan Watt being an example (see cuttingthroughthematrix.com).
There are other well known alternative researchers who have put out information and research on “chemtrails,” also called aerial spraying or geoengineering.
Officially, academics have talked about geoengineering and have pretended it hasn’t already happening (see 9 minutes into the film, “What in the World are they Spraying?”)
Bill Gates, founder of Microsoft and the Gates Foundation, has talked about geoengineering since his infamous Ted Talk in 2010 and more recently in terms of “dimming the sun” to control “global warming.”
In science fiction and futurism, the same type of project is called terraforming.
Matt Landman is a source of information. See, for example, https://duckduckgo.com/?t=ffab&q=higherside+chats+chemtrails&atb=v263-1&ia=web and his website frankenskies.com, including his documentary.
Another researcher–at this subject for years–is author Elana Freeland.
I’m not necessarily endorsing everyone’s various opinions and philosophies, but these are sources for further research into the facts.
I have collected additional information, especially via Alan Watt: More posts on this topic.
