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.

The main reason I'd be hesitant to get one is because I don't really ever set my thermostat to heat. Even during the once-in-a-lifetime freeze a few years ago, we never ran any heaters (granted, we live in an apartment, so only like 2.5 walls are exposed to the outside - would be very different in an actual house, but I'd still rather opt for better insulation, a single space heater, and a heated blanket over spending that same money on a heat pump that does nothing for years at a time).

If you live in an apartment, it's not your choice but the owner's? And a heatpump is an air conditioner in the summer. They cost about the same so why not have the option to heat too?
