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.

Calling it staggering is really overselling it.

My renewables are staggeringly vast

Honestly I'd hedge my shit across multiple fuel sources and types if I could afford it.

And let's be clear that the ability to turn off the valve to petro-fuel ALL AT ONCE is a power that will be useful politically.

I'm a smalltime farmer on ~4000 sqm (~2 acres). I can't think of anything that would replace my diesel tractor effectively now. Even though I'm just using it to till from time to time, it uses a lot of power to do that. An electric option that could tick all the boxes would be cool, but there's no way I could afford that. For large-scale farmers, I don't know what can exist that would meet their power and timing needs.

I am looking forward to getting an electric car as my next vehicle, though.
