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.

These kits absolutely can push power into the grid, usually with payment for the generation. Just because they may not be allowed where you live doesn't mean they don't exist.

If you happen to have an old Ferraris meter without a ratchet it can even run backwards when you produce more than you consume. And, of course the 800 Watt EU limit is a worst case limit. If you feed in on a dedicated (no other consumers or generators) line with its own fuse and sufficient wire crossection you can feed in up to about 2 kW. Be aware that the fuse will not trigger if you have a near-short while you generate peak or near peak which can cause overheating and is a fire hazard. While none of the above is legal and you will lose house insurance in case some electric-related fire event occurs it is safe technically.
