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.

I'm going to be doing this in my home, but it likely won't happen for another year. Due to the existing construction and the size of my property, it will have to be the most expensive option (vertical bore), and other areas need attention first.

I want one, I just really want to avoid a situation where I shell out for a system, and then next month Biden says he'll give a few thousand extra in rebates.

I want one and will replace my furnace when it breaks down, but it doesn’t help that at least around here an air source would cost about thirty percent more to run than natural gas. That wouldn’t be the case if I had to pay the true cost of the damage that the natural gas causes of course, but until that happens a lot of people are going to tend towards the cheaper option.

I’m also not to hopeful for a proper carbon tax anytime soon for reasons that Australia just demonstrated. It’s a tax on all citizens that disproportionately affects the poor and which energy companies will use as an excuse to massively hike rates, even if it never affected them in the first place. Naturally, when Australia repealed it most energy companies reacted by rasing rates again, but many americans won’t question it when Murdoch news blames that on climate regulation too.
