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.

I will just post this here from a previous time this was brought up: While China is building a LOT of renewable energy and it should be applauded for it, it is not the only thing that are building. China accounted for 95% of the world’s new coal power construction activity in 2023, according to the latest annual report from https://globalenergymonitor.org/

While that is true, I believe that those are all replacement power plants. As in there was already an old much dirtier coal power plant in operation that needed replacement. If that is also the case, emissions may have finally peaked and we can begin the long hard road of cleanup and total phaseout.
