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.

Huge respect for the man but

His research trip in 2023 meant taking 40 days to travel from Europe to Bougainville and 72 days to return. According to his calculations, carbon emissions from this slow 28,000-kilometer (17,400-mile) round trip was 10 times lower than flying.

Taking 50x the travel time to safe 10x in emissions... I don't think I have it in me. I accept to replace a 45 minutes flight with 7-10 hours of train (and do it often) but that's about the limit of my sanity.

I have to agree, but I also respect the hell out of anyone willing to stick to their beliefs this hard.

That's some Willy Fog lecel of perseverance though. In fact, Willy Fog had better options before air travel became a thing.

The real travel are the friends we make along the way
