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.

Appreciated, and I understand a dry heat is more pleasant than a swamp and that the UK doesn’t have AC by default. But I mean very specifically that Brits will seem surprised every year that June is hotter than May. You suggest they get A/C and they say “nah, it’s just a heat wave, innit?”

It’s a three or four month long “heat wave” and it happens every year.

Now that heat pumps are becoming a norm, air conditioning will become a moot point. But for real, for us, we'd get like two days of summer and it would rain for three months straight, hence the reluctance to invest. It's only thanks to climate change that we're now getting sustained heat. This is genuinely a novelty to us.
