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.

We've known this for more than 50 years. If policy makers won't start making fossil fuels adequately expensive (which they won't), nothing will change.

We have millions of people who look at combusting more fuel and dumping more CO2 into the atmosphere as 'recreation', and base tons of entertainment and leisure upon it. You're entirely correct - from cruise ships burning bunker oil to dirt bikes nascar F1 vroom-vroom car culture and all the 2-stroke lawnmowers and leaf blowers - it's all gotta go. And the only way to convince them that the world is on fire and we absolutely must do this whether they like it or not is to price petrol according to it's impact.

I wish there was a way to make this happen before tens of millions die.
