So there are papers. There are studies on tons and tons of things. One of the things you learn really studying science is that there are always papers, and you really have to immerse yourself in a field to see what’s actually happening.

People who believe in chemtrails need to prove that the it’s being done, is being done at industrial scale (not just a few one off experiments), and that this is harmful to human health or the environment.

Ocean fertilization to soak up CO2 has been extensively studied and in that case there are documented experiments, but we are not doing it at scale… mostly because nobody wants to pay for it and because we are not 100% sure the CO2 will actually be sequestered. There’s also some concern about side effects on ocean ecosystems.

A lot of things get studied.

Of course the real conspiracy I keep hearing is that this is some kind of mind control thing. Why? Even if that were possible, why bother when you can mesmerize humans at scale with mindless slop scrollers like TikTok and program them like a zombie army. Much cheaper and done 100% in the open.

I've never taken much of an interest in the chemtrail thing, but it does seem funny that governments are proposing to do more or less the same thing they denied doing!

I can't see this being the answer though. Maybe I'm wrong, but it wouldn't be the first time environmental measures have proven destructive. Some of the most invasive pests have been brought in to control a less invasive ones e.g. cane toads in Australia. The road to Hell is paved with good intentions.
