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.

Not on a per person basis. China also does the most to combat climate change, purely by virtue of its population. It also does the most research, has the most homed people, has the most fed people, delivers the most babies etc etc.

When dealing with different countries with wildly different populations, it's the amount per person and change per person that counts the most.

Unfortunately, by dividing by country, it becomes a game theory problem in that the actions you do don't have an effect. It's collective actions that work. As this becomes more imperative, the cost of those not acting will not be borne by countries that are and they will be punished in trade tariffs.
