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.

Yes and no. Yes they are built to be cheap and minimally code compliant but they are also way too fucking big. Most of the new construction I see is shitty ass mcmansions at 4k sqft and up with 5 bathrooms and 50 windows, when it could be 2800 sq ft to something close to passivhaus standards (PGH), all electric and very, very efficient for the same price. But somehow these asswipes needs a 5th bathroom to shit in so we are stuck with them optimizing construction to size and number of shitters, not efficiency. Unaffordability is a real issue but it's a cop out to shitty oversized inefficient housing. We need to use the codes and tax structures to build smaller efficient homes, which will actually help affordability.
