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.

40% of global ship traffic is simply moving fossil fuels around! Renewables make much of this traffic obsolete (slrpnk.net)

in the US i found figures ranging from 6 to 12% the largest sector by usage is road traffic using ~45% of the oil in us

here's a chart for EU

Fascinating! Thank you for sharing!

I bet the 12% are direct use (pipe tail), not all the shit that goes into building and maintaining this orchestrated dance, i.e. at lvl 1 the roads, tires, cars, fuel transport etc. and what does into maintaining and operation the infra to keep lvl 1 gking etc. But accounting (oil, co2...) for end products is surprisingly difficult.
