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.

Surely, by that logic low prices would also drive demand and increased useage?

They do. What you actually want is high prices for consumers and low prices for those doing extraction. That's the idea behind a carbon tax or sabotage aimed at the oil and gas midstream.

So you’re saying high prices lead to increased useage over low prices and low prices lead to increased useage over high prices at the same time? Does this mean average prices lead to decreased oil useage?

Usage has increased no matter the price for decades. Using pure price mechanisms to globally cut fossil fuel use means splitting consumer prices from wellhead prices.

Useage has increased, but for your first comment to make any sense the war’s effect on prices must have caused an increase over and beyond a world in which it didn’t happen.
