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.

Most locations aren't like that; they're injecting into oil and gas deposits with the risk of subsequent leakage

Enhanced rock weathering is very cool if it can be made to work at scale. Most examples have issues with needing a lot of energy to mine and pulverize rocks

They are looking at using Tailings storage facilities in mining for this reason

with the risk of subsequent leakage

That risk is like telling:" humanity will go down due to a eruption of a super vulcano"

But i agree carbfix is no solution for global scales.
