Thanks, I know the official anwser.

But weather modification is a well known scientific discipline that does have many applications of atmosphere modifications. The mere fact they don't do it publically doesn't mean they don't do it at all.

Wiki:
In the early 2000s the USAF released an undated fact sheet that stated the conspiracy theories were a hoax fueled in part by citations to a 1996 strategy paper drafted within their Air University titled Weather as a Force Multiplier: Owning the Weather in 2025. The paper was presented in response to a military directive to outline a future strategic weather modification system for the purpose of maintaining the United States' military dominance in the year 2025, and identified as "fictional representations of future situations/scenarios."

It's junk science, along with cloud seeding, and others, having no significantly measurable effect.
It's all down to the energy, it's on a completely different scale, beyond what humanity can currently output.

A single volcano outputs more energy than a large nuclear stockpile, blocking out the sun over multiple countries, and affects temperatures for a year or two, and even that isn't so significant that we should worry about.

The main factors are on a completely different scale:
• Distance to the sun.
• Earth's mass.
• Earth's surface area.
• Earth's reflectiveness, how much of the energy gets sent back out.

Most of climate "science" is straight up fake, with the academic establishment buying into their own propaganda over the decades.

Bonus: Most of the talk about mega storms died down after NASA proved it's impossible on Earth due to lack of surface area.
They were trying to understand the Eye of Jupiter, a 400+ year old storm.

although there have been sporadic attempts to influence weather ( silver iodide [ seems like awfully expensive stuff to be scattering in bulk ] to nucleate droplet formation ), the airlines do not routinely add anything to jet fuel. anything other than carbon and hydrogen in the fuel severely reduces the lifespan of jet engines. the contrails you see are not an indication of anything but disturbed air in the stratosphere, with a little extra water vapor in it.

and, contrary to some of the theorists, weather modification cannot be directed to send a tornado to Enid Oklahoma on June 3 of this year. you can scatter sulfur to make high clouds, but you can't control where it goes. it's a whole lot like releasing a contagious disease germ and hoping it makes your enemies sick.
