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.

Chinese President Xi Jinping on Wednesday told the United Nations that by 2035, his country plans to reduce its greenhouse gas emissions by 7%–10% below its peak, and called out “some countries” for moving against the global clean energy transition

Alongside the economy-wide emission reduction goal, Xi said that within 10 years, China plans to increase its installed capacity of wind and solar power to over six times its 2020 levels. It also plans to boost the share of non-fossil fuels in domestic energy consumption to over 30%.

The difference is they might be able to do it, vs us who alternate between electing virtue signaling, ineffectual center right sheep, and outright fascist, climate change denying monsters.

There is more than just the US and China, despite what Lemmy says.
