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.

Cycling like the Dutch would slash the world’s carbon footprint (www.euronews.com)

Dutch people cycle an average of 2.6 kilometres each per day. If this pattern was replicated worldwide, the study suggests, annual global carbon emissions would drop by 686 million tonnes.

This mammoth figure exceeds the entire carbon footprint of most countries, including the UK, Canada, Saudi Arabia and Australia.

They make ebikes now that really help with hills

As someone who's relatively recently started riding a motorcycle I feel like at that point skip the half measure and get an electric motorcycle. Really don't get the focus on bycicles in these discussions since I feel like it's liable to make people think it's a lost cause in areas like mine where the city is quite literally on a 20 degree slope minimum.

Wish I had an electric motorcycle to a degree but the 40 year old 110 is far more workable with what I intend to do with it what with reserve fuel and whatnot. Is it insane to plan a trip from SoCal to Washington on a 40 year old motorcycle? Yes. Will that stop me? Fuck no. My first trip up there was with a slowly dying 95 four runner I've got to up the standard set by 19 year old me.

True, but 4 hills = 20 miles.
