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.

markets don't work that way. if you reduce demand (i.e. fewer people consume fossil fuels), and supply stays constant, that means that prices go down, which makes fossil fuels cheaper until people start using them again. eventually it balances out at an equilibrium state. supply and demand

Yes, thats assumed. However we are taking into account that machinery rusts away quickly. If you stop one refinery for example, that's not a smooth change, its an abrupt step. If we stay steady below the usual high, then trying to come back will be expensive. For that reason we'll see the price increase slowly...you need the fuel, so its a seller's market, they need to get paid as if their load was double in case they need to double. At some point it might drop a bit until it becomes a luxury item.

Here's an example where the price is going up became the supply keeps dropping and the demand keeps increasing regardless of the supply situation:

The same would happen to ice cars. People still want to use them if they have them, but the market keeps shrinking.
