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.

EBikes are awesome. I live in a hilly area where riding is tough. EBikes allows people of all ages and abilities to get out. Even with the assistance you still burn calories... as long as it's assisted peddling and not the illegal bikes I see delivery guys riding.

I ride road bikes but when I get older and less capable I'll certainly invest in an ebike.

I don't begrudge the deliverers their powered bikes, they have a tough enough gig and it's one less car. I do wish e-scooters would stop going fast among foot traffic though. My kid moves pretty unpredictably, and has had near misses in pedestrian areas
