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.

There is still last mile/miles concerns. Not every grocer can have a rail spur, but it can be serviced by a local fleet of electric trucks. The ultimate solution is a mix of various electrified transport.

Freight trolly has been a thing and is still used in some places. Between trains, freight trolly, and cargo bikes you could cover basically all urban use cases and most rural use cases.

Logistics predatss cars and trucks by quite a bit, the last hundred years has been an aboration masquerading as the norm. Those old solutions can be brought back.
