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.

Yes and no. All externalities that impact others are non-consensual, but you could extend that logic to the consumption of any finite resource and even moreso for inefficiency — the current markets inefficient consumption of that finite resource means there is less for everyone, and increases the price and opportunities for everyone, with people born later at an inherent disadvantage. You could extend that logic further to any alteration of the environment or natural world whatsoever; to all human consumption. Using any resource creates an external degradation in the availability and opportunities of everyone else regarding that resource.

The free market doesn't have a solution though — essentially zero capitalist orgs have chosen to voluntarily consume less or cease emissions. The ones that do are at a competitive disadvantage due to higher costs vs competitors — laws and regulations are required to level the playing field so the competition is fairer... A free market solution is an oxymoron. The free market created this crisis.
