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 were supposed to hit peak emissions. Why won’t they stop rising? (www.vox.com)

Big polluters know their resources are finite. They’re deliberately cooking the planet because after some threshold has been reached, they’re going to pivot their enormous infrastructural and industrial capacities into geoengineering.

We’ll be paying BP and Shell to keep the planet cool eventually.

That's indeed tinfoil-hattery. These companies care about quarterly profits and they extrapolate the future from the past (where nothing bad ever happened to them). They may find another business model eventually but they'll make it up on the go.

They're extracting as much as possible until the starship is ready and the base on mars is complete.

Bruh even a +5°C war-torn Earth is an infinitely better place to live than Mars. Mars would just be quieter.
