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.

Although he referred to multiple “Manuals,” the president’s Truth Social screed is really about a single manual: the Federal Judicial Center’s Reference Manual on Scientific Evidence. The Reference Manual serves “as a go-to document judges can use when they deal with issues involving scientific testimony.” For the first time, the most recent version of the manual contains a climate science chapter. It describes the hard scientific evidence that fossil fuel burning is influencing extreme weather events. This science is anathema to the oil industry and to its conservative supporters, including the president, and they have responded by attacking the manual and its authors.

He hates anyone who knows more than he does. That's almost everybody.

its always funny when he learns something and in his speech says not many people know this followed by something everyone fucking knows.

"almost" is doing a lot of heavy lifting here...

That is everyone except a handful of designations. Everyone except babies, the dead, and the theoretically alive such as Mitch McConnel.
