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: Graph of temperature as observed with significant warming, and simulated without added greenhouse gases and other anthropogentic changes, which shows no significant warming

How much each change to the atmosphere has warmed the world: IPCC AR6 Figure 2 - Thee bar charts: first chart: how much each gas has warmed the world. About 1C of total warming. Second chart: about 1.5C of total warming from well-mixed greenhouse gases, offset by 0.4C of cooling from aerosols and negligible influence from changes to solar output, volcanoes, and internal variability. Third chart: about 1.25C of warming from CO2, 0.5C from methane, and a bunch more in small quantities from other gases. About 0.5C of cooling with large error bars from SO2.

Recommended actions to cut greenhouse gas emissions in the near future:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

Computer simulations reveal that spraying sea salt aerosols may keep global temperatures near 2020 levels as air pollution falls—but may also redraw regional weather patterns. (www.anthropocenemagazine.org)

Both? Both is good.

Because if you read the article you would know that this only works to suppress another degree of global warming that is looming over our heads, one that will happen if and when we stop polluting the planet.

At worst, we could use this to smear out the effects of climate change to allow ecosystems a little more time to adapt. At best, carbon capture becomes viable at some point in the next thousand years and we can gradually stop spraying sea salt while reducing atmospheric CO2 to prevent most of the damage that extra degree would have caused.

(also, plants are the best construction material we have; lumber yards are cool even if the owners aren't).

Maybe we could try some sequestration, too. But only after we stopped flying and consuming like vultures and took the money from the rich. ++ Its equally important to stop polluting the seas with our garbage, reducing CO2 won't help anything if it's the only thing we do.
