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.

emissions down in last 10 months of 2024. Very likely that trailing 12 months are down too (not covered in article, but something they will pick up)

Your graph will make China look better when it includes 2024. The only thing you can control on energy mix is growth rate. Adding more fast enough. You should go easy on praise for US, as Ukraine war is both a massive emission increase, and scramble for new "good oil" supply developments, and deprioritization of global sustainability. The IRA, while better than nothing, is a scheme to protect monopoly profits using "climate change as a profitability/relevance economic engine" for the US market, and the solar/battery/EV tariffs designed to make actual progress as slow as possible.
