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.

Just to give it a real world example. Between 2012 and 2022 Chinas electricity generation from coal increased by 1,675TWh. Globally it only increased by 1,329TWh. So coal emission would have decreased, if China would have built some sort of low carbon power generation instead. The other country adding a lot of coal in that timeframe was India with 576TWh. To put that into perspective high income countries generated 2,192TWh from coal in 2022. So just working in the rich countries does not solve climate change alone(it has to happen thou). All poor countries should however also be aware that even if they get rich, they face the same problems rich countries have today, of shutting down perfectly good fossil fuel infrastructure to save the planet.
