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.

No, that’s not how it works in the general case. There are ways to setup a house to back power but it’s more complicated than just plugging it in.

So what you're saying is that the general case is that it feeds back into the grid unless there are additional measures taken? But at the same time, it's not the general case? Huh?

Without proper safeties in place back flowing power to the grid becomes extremely dangerous for line technicians

Which is why, where I live, you have to register your devices with the utility company.

I was saying the general case is that they aren’t tied to the grid, but that they could be setup to do so. I’m almost definitely wrong about how often these are tied to the grid though.

Yup! I’d be shocked if a country didn’t make you inform your utility.
