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.

Massachusetts is behind on its climate goals. Could tracking vehicle mileage be the answer? (www.wgbh.org)

You could just slap a carbon tax on it, no need to track people

Cars aren’t even the main problem. When you burn coal, oil or gas to produce electricity and heat for various purposes, that’s covers vast majority of the emissions. Maybe start with the biggest emitters?

I'm not against that either, but the article mentioned tracking cars, which sounds expensive. Charging a carbon tax on fuel is almost self reporting
