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.

Don’t worry. Some private company will come in and sell you something to fix it. I mean, it won’t and it will be a total scam. But they will sell it to you. And gosh darn it, you will buy it.

It looks like America is self-destructing. I'm not sure that's a bad thing for the planet in the long run. But sure, it'll cause a real mess going down.

And of course it is tragic. But somehow I'm less worried about the climate change aspect of all this - at least on a planetary scale - compared to how worried I normally am about climate change.

halting the Environmental Protection Agency’s progress on dealing with and researching PFAS

Not directly global warming related, but especially sad. PFAS is a global polluter as it gets into the rain cycle. Freshwater fish everywhere are unsafe to eat.

I'm angry at the baseless ignorance of putting a GDP cost to global warming. It is a wealth and quality of life cost, but spending can be just as high or higher. The US is at especially high risk of collapse with low housing build rate, and vehicle inflation from tariffs. Insurance inflation must necessarily significantly reduce quality of life and property values as disaster risk and agricultural yields are impacted. Property devaluations is bank failure risk.

Relying on US was always a poor plan, as it is most politically corrupt nation on earth. Far bigger than US climate policy, however is ending war in Ukraine. Immediate 3% drop in global diesel use, and lower oil prices that mean less lobbying for climate terrorism, and drilling expansions. Rest of world is more important than US for emissions, and decoupling from its oil extortion attempts is a likely reaction to US belligerence to former allies.
