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.

A record surge of clean energy kept China’s carbon dioxide (CO2) emissions below the previous year’s levels in the last 10 months of 2024. (www.carbonbrief.org)

'Last 10 months' is a really weird way to word that. 10 months is literally over 3/4ths of the year. It's fucking embarassing at this point that the US has fallen this far behind when we should have been leading the charge on this from day 0. Still good news though and glad to know China is making a concerted effort.

Year on year Chinas emissions went up by 0.8%. That is why. Btw the US emissions fell by 0.2%. However with Trump that is not going to last.

Yeah this is the 4 years where China becomes the leader and the US lags behind. Hopefully the damage can be limited by industry.

Great news and much needed. Chinas emissions falling could very well mean global emissions start to fall. It also obviously weakens the fossil fuel industry in the rest of the world.

Its sorta sad that its 2025 and its like. hurray we did not increase. I will never be able to get the thought out of my head of what the world would be like if we had gore instead of bush. climate action instead of drill baby drill 25 years ago. Unfortunately we do have to get to the point of not increasing emission across the globe even if it should have happened ten or twenty years ago. I mean it should have started 50 or more years ago but we don't really have an excuse for the last 20 years.

Widely distributed local sources of renewable energy generation is the most straightforward path to reducing global conflict.
