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.

After reading the article it sounds like compromise language to get fossil fuel producing countries to sign on to a statement. I guess the idea being if carbon capture technology improved in the future that could be done. They're not talking about the carbon capture from the air stuff, which is pretty dumb, but carbon capture at point of origin of emissions where co2 concentrations are much higher, like at power plants. Probably also dumb, but maybe slightly more feasible with theoretical future technology that doesn't exist. Overall it doesn't mean much though, it's a language compromise to get more countries to sign on to some symbolic statement the conference will issue. I don't think any new major actual agreements are being planned for this conference. Though in a deal unrelated to the conference, it sounds like the US and China have made an agreement to lower methane emissions they may announce there.
