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.

With all the oil burning from both the Iran war and Russian invasion, I doubt that optimism, but it just a gut feeling seeing these videos of huge flames and smokes. I hope they are right ๐Ÿคž

Most of that oil would've burned anyway, just a little bit at a time, inside a combustion chamber, after being refined and distributed somewhere.

When an oil pipeline or well catches fire, it burns in a spectacularly dirty way, but the net CO2 emissions in the atmosphere is actually reduced from shutting down that facility so that it can't process and export as much oil anymore. Meanwhile, the logistics and pricing effects probably destroy demand, so that the world as a whole burns less oil afterward.
