Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.
As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades:
How much each change to the atmosphere has warmed the world:
Recommended actions to cut greenhouse gas emissions in the near future:
Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

I agree with that. It seems overblown that some folks were opposed to spreading two kilograms of limestone dust and measuring the result.
A single aerobatic flight of an ultralight aircraft with a smoke trail probably requires more pyrotechnical material, not to speak of fuel. Not to speak of a proper passenger or cargo flight. Not to speak of a satellite launch.
People already do the things anyway, only without properly understanding the results.
As for the argument that "then everyone will start experimenting" - well, that depends on the result of the previous expriment, does it not? And some do it anyway. China has a weather modification bureau, Saudi Arabia practises cloud seeding to increase chances of rainfall, etc.
I agree. While I am very skeptical that high altitude geoengineering would work, to me at least this massive fear around studying the upper atmosphere in these ways just makes it more likely that a rouge nation will go ahead with it anyway, precisely because these large margins of errors provide a hope that it could save millions of their citizens lives for negligible cost.
Of course, the other possibility is that it might actually work as expected, we did after all see a big change post fuel oil sulfur regulations, in which case we will have killed more people than died in both world wars purely out of unfounded fewrmongering.
Given the number of real people who are dying today because of climate change, I feel that it is negligent to not at least look into every card we have at our disposal to save lives.
