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.

I live in San Diego, one of the cities getting its grant money pulled. San Diego is a near ideal place to have a bike-centered transportation system. Inclement weather is rare, and I use a bike for my daily transportation. I bike more miles per year than I drive. There is a decent bike path network, but there is lots of room for improvement, so it sucks that the money is being pulled. Cargo bike and ebike adoption could make a lot of sense for so many people, but a lot of people are rightfully afraid of dicing it out with cars.

I just got back from visiting family in Encinitas and damn near everyone has a bike there, majority of them are e-bikes.
