Climate - truthful information about climate, related activism and politics.

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.

My point is that the US will always prioritize global domination over climate sustainability. Trump's first term did include private/state level US mandates for sustainability as a reaction to dooming-fascism. That movement weakened under Biden. Local hope movements are an uphill battle, but still possible.

Nature of US politics, and a popular vote favouring extreme strengthening of oligarchy, can again result in a strong pendulum movement away from climate destruction, but the next zionist/neocon candidate the DNC provides us will not prioritize global cooperation/sustainability any more than Biden did. Either US collapse, or a political movement based on UBI that disempowers the US empire will lead to lower US emissions.

I wouldn't say that the movement towards state action weakened under Biden; we got some great examples of it, such as the requirement for renewables in Minnesota.
