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.

Really wish this point was hammered harder, it's so unbelievably stupid, the way we're deliberately handing this opportunity off to anyone else. The US became economically dominant in large part by being well positioned to exploit and develop huge emerging tech scenes / markets, and then doing that by funding R&D, projects, etc.

We're again positioned to be absolutely dominant in one of the most important, or maybe the most important, tech booms of humanity so far. "Conservatives" should love the idea of getting viable green technologies first, it's THE way to keep the global order similar to how it's been.

Not that I personally want things to stay like that per se, but regardless better green tech sooner is generally better for the whole planet. It's insane to watch these idiots just focus on the near term and literally give away the keys to power for the next century.

I would also expect an I crease in carbon tariffs worldwide. They are allowable under wto rules and with the USA implementing tariffs, other countries will seek ways to do the same while protecting themselves. The USA not following two rules would be a boon to China and Russia to ignore patent laws. It will be carrot and stick.
