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.

hydrogen blends [...] compared to gas

I get the jitters reading that. They're both gases. Is it so hard to write "methane"?

I mean if someone says they have gas central heating I wouldn't question which gas it is. In context I think it makes perfect sense. Feels a little pedantic tbh.

It might be propane. Indeed very unlikely for central heating. But pretty likely if they're cooking with "gas".

They're both gases, but when somebody says they have a gas heater, I'm not about to ask if it's xenon powered
