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.

The National Oceanic and Atmospheric Administration is narrowing the capabilities and reducing the number of next-generation weather and climate satellites it plans to build and launch in the coming decades ...

And just like that, the US bows out of another scientific segment we could have been leaders in. It also would be cool if an asshole with a 4 year term wasn't able to screw us all for generations so easily.

Executive branch needs a reboot. Too much riding on good faith, with the loopholes exposed. We need to fix it, or this just happens again.

Not just the executive branch. The US is a century or longer overdue for a new constitution.

The current one is just stale 1700s philosophy and patches of very disparate quality.
