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.

If So Many Americans Care About Climate, Why Don’t They Vote Like It? 11.2 million. That’s the number of Americans who rank climate as a their top priority but didn’t vote in the 2024 US elections (coveringclimatenow.org)

Voting is the baseline. The absolute minimum effort required. Its the least effective yet simplest thing to do to fix things.

Anyone who doesn't vote doesn't get an opinion. But pretending that voting will magically fix everything on its own is equally dumb.

Given that voting doesn't really affect policy (like at all, studies have shown this), I don't think it can be considered the baseline. If you want to count yourself as politically active and not just passively acquiescing to the system, you have to be involved with organizing your community.

"thoughts and prayers are the baseline for gun control" and other supernatural beliefs meant to steer people away from actually changing anything
