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.

What If the Clean Energy Transition Costs Much Less Than We’ve Been Told? Talk about astronomical costs of a sustainable economy is leaving out some of the savings of using fewer fossil fuels (insideclimatenews.org)

It literally doesn't matter. The financial cost is of no importance to sensible people - we know that the flooding of coastal cities, being unable to grow food, millions of climate refugees, etc. outweighs any short-term cost of slowing the climate crisis. On the other hand, the financial cost is the only thing of import to fossil fuel companies, because they are capitalists in a capitalist system - short-term profit is their priority every time.

The denier line has moved on from "it's not human caused" to "it's too late/expensive to do anything about it anyway", aiming for pessimism and doomerism to let them continue business as usual.

Having things like this we can counter with helps people argue and motivate to continue the fight.
