Climate - truthful information about climate, related activism and politics.

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.

Ah that scam of carbon offsets. Guys let us pollute a little bit more, we promise we'll pull it out of the air later.

This is about carbon capture and storage (which takes energy and concrete and by this report doubles the carbon impact of just burning the coal).

Yeah its largely a thing for carbon offset regulations. Like if you emit too much you owe fees but if you "offset" your emissions in some way you can deduct that from your emissions. Stuff like paying tree planting organizations, and imvesting carbon capture technology. The carbon offset scheme dont work, we have to emit less

You are right, but this isn't about offsets.
