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 in a similar situation. Finding a good installer is tricky. I'm in a terraced property so similar there as well because there's very little space to install an air source pump. In an ideal world everyone would have 27mm piping but in my case I could get away with less and some better insulation. Sure it might not achieve the maximum efficiency possible but I'd hazard it's at least a better than our current boiler.

For now though I'm probably going to stick with the boiler with an OpenTherm stat to keep it running low. I'll try and bump up our insulation and hopefully things improve in a couple of years when the boiler gives up the ghost.
