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.

You're a bit confused about buffer tanks. They are thermal stores and just store primary heating circuit water.

The water from the buffer tank isn't the hot water from the tap. The water in the buffer tank will be used to indirectly heat mains water. Either through a plate heat exchanger or an unvented cylinder.

I am not confused, although maybe my wording was confusing.

My point is, that generally speaking, you can't use water from the same tank to heat your drinking water and to cool your home (because it mixes and the resulting temperature will fill neither requirement). There are of course tons of variants of buffer tanks, and in some cases there are bypasses or there's a physical separation between heating water and (water used to heat) drinking water
