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.

New documents show how a deceptive PR strategy pioneered in 1950s California first exposed the risk of climate change and then helped the industry deny it.

Isn't the exception biochar?

[–] silence7 2 points 1 week ago

Maybe. It's of fairly limited resale value compared with the cost of producing it and transporting it. I don't know of anybody making it near me with the expectation that they can profit as a result; I mostly see small-scale production when doing things like disposing of hazard trees

Biochar is an attempt to make a product from the effort, and it's a leading one we have. It's still better for the net result to just bury the carbon without trying to gain anything. But like I mention above, that's a literal money sink and no company would do that without being subsidied for the effort.
