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.

Have you lived anywhere other than a dense city? Mass transit doesn’t work everywhere.

Mass transit works just fine in rural areas when it’s properly constructed. Busses are about the single worst option for mass transit, and options like high speed rail excel in connecting rural areas to urban and exurban areas with better job opportunities and connecting urbanites to rural areas, both of which bring money to the rural areas.

Switzerland has one of the best rail systems in Europe yet it has more cars per capita than the UK at 604. The US is at 850. So creating a mass transit system in the US equal to the best in Europe would only reduce car usage by 30%. That's the best possible.
