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.

I'm expecting a relative near future where Americans are buying ever larger gas pickup trucks for 100K on credit while the rest of the world are buying small EVs for <20K, and switching to alternative forms of transport. And the Americans will swear up and down that their way is the way of "freedom".

So, the present, then?

The present for the US yeah, but much of the Western world have been following the US trend in many ways. I suspect (and hope) that it will turn back in the opposite direction as the world is flooded with cheap EVs and the public transportation work continues, as long as the rest of the world doesn't follow the US into the abyss.
