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.

Politicians across the spectrum want more housing. Apartments are a great answer, because they also slash carbon emissions in a big way. (grist.org)

Nothing against single-family homes, but apartment buildings and condos are much more efficient for a number of reasons. For one, residents share walls, floors, and ceilings with their neighbors, surrounding them with excellent insulation. Secondly, the square footage of each unit tends to be smaller than detached homes, so there’s less air to manage. Accordingly, it takes less energy to climate-control apartment units and keep people comfortable: The typical resident of a downtown high-rise emits one-third as much greenhouse gases as a resident of a detached house in the suburbs.
