People often seem to confuse “geoengineering” (the theoretical deliberate modification of a planet or geographical environment to suit a purpose) with “climate engineering” and “weather modification.”
Further confusing is the fact that “weather wars” are often included in the mix without distinction.
Allow me to clarify the terms in quotes.
Climate Engineering is our attempt to reduce the effects of climate change on Earth based on the premise that a buildup of greenhouse gases, especially CO2, are causing a warming trend. This can be approached in one of three ways:
1. Combustible fuel use reduction, especially via alternative energy sources
2. CO2 removal, conversion and/or sequestration
3. Solar radiation management (SRM)
SRM is considered the only feasible approach by some climatologists; others question the potential negative side effects, some of which may not be predictable. However, no widespread SRM programs are in place today, though some people believe clandestine programs have been ongoing, largely because preparations have been made by companies that would profit from SRM programs and eager climatologists have endorsed it for lack of better ideas. Still, no proof of this has been offered as far as I know…
Weather wars are a real thing, and our military forces have used weather in the past (e.g., Operation Popeye in Vietnam) and have prepared weapons that can affect the weather (e.g., HAARP) among other things. However, even if HAARP or other scalar instruments can cause storms, and even if they can use enhanced jet contrails in some way, these weapons are not the cause of contrails or “chemtrails.”
Another part of weather warfare includes chemtrails in the literal sense– toxic substances sprayed by aircraft as a bio or chem weapon– but this practice is strictly banner by international treaty.
Weather modification, on the other hand, is a common and prolific practice throughout the world, including the US and most modern countries that require more water.
