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)

I believe the system is fundamentally broken but I still participate because you can't fix it by doing nothing. But yes, my coworkers are not people who's opinions will be changed by fact and reason. They're also the same people who say, "facts don't care about your feelings." Imagine that. But then they get all bent out of shape about how "no one is doing anything about this!" but then refuse to vote. My guy, you're not doing anything either!
