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.

New England and Alaska are about to deploy a lot more heat pumps | The EPA awarded these cold regions with a combined $488M to replace fossil-fueled heating with efficient electric heat pumps. (www.canarymedia.com)

This is great, living in MA I see a majority of houses relying on old oil heating systems. Just checking Zillow listings and seeing the big ugly black tank in the basement it's very common. Mini split systems with heat pumps have started popping up more, especially in these older houses where it's easier to install than trying to install duct work for a full sized HVAC system.
