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.

Volcano sulfur emissions are well known and the same thing from shipping emissions.
@Einskjaldi @silence7 sulfate aerosols cause acid rain, respiratory irritation, and can even cause severe cardiopulmonary diseases leading to premature deaths.
But even if we could find some reflective aerosol that isn't toxic, computer models of SRM/geoengineering have shown frightening negative side effects including slowed global circulation leading to an uneven temperature gradient that would disrupt the jetstream, leading to increased atmospheric blocking in the form of stagnant high-pressure systems that lock in hot air for extended periods a.k.a. "heat domes" and effectively exacerbating some of the worst problems the climate crisis is already causing

Yes, like most cases where this is brought up the local case is what you're referencing but it doesn't affect your breathing if it's released over the open ocean. And the point is that we have been polluting sulfur in large amounts already and we've just recently started doing that less.
@Einskjaldi so you want to pollute the world with toxic chemicals and it's going to make everything worse. Sorry, are you a Captain Planet villain?
It's not toxic is the point, and it's a tiny fraction of what volcanoes put out. Things are like you can can do nothing and be smug as 90%of all species die off or do everything you can to cool the planet.
