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.

Butter, milk, beef, chocolate and coffee accounted for about 40 per cent of the increase in food prices over the past year, despite making up barely a tenth of the typical household food basket, according to the Energy and Climate Intelligence Unit (ECIU) research group.

Switching to a plant-based pattern solves the top 3.

So who are pushing the false narrative that it's wages and taxes that are driving food-price inflation? Oh, right: "industry groups."

That probably also means they're using recent events as an excuse to fatten their profit margins.
