Heat pumps are so perfect for a climate like the UK.

Wait until the AMOC collapses. Ever had -20℃ weather for four-plus weeks at a time in Jan/Feb? That’s what you’ll be getting when the AMOC collapses.

Very few heat pumps sold anywhere before 2020 were able to reliably handle that kind of cold. And I’m betting that near-0% of the heat pumps installed in GB are of that kind, even the ones being installed right now.

Our heat pump stops working around 32F/0C. I read that they should work down to around 0F/-17C, but that has not been our experience.

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.
