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.

Heat pumps were supposed to transform the world. But it’s not going as planned. | Heat pump sales, critical to the transition to clean energy, have slowed in the U.S. and stalled in Europe. (wapo.st)

Not gonna lie: it's my own fault on this one.

Switching my furnace and hot water heater to heat pump models is 100% on my to-do list for my house. There are even federal rebates / tax incentives I could have taken advantage of this year (hopefully they'll be available next year). I just...haven't. Mostly it's just due to having to schedule work for ancillary parts of the process like removing the flues and replacing the metal panels on the roof where those are now. Those steps aren't strictly required, but I'd like to have them done at the same time.
