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.

New electric vehicles cost thousands more than similar models that run on gasoline. But a growing number of shoppers are discovering that for used cars, often the opposite is true.

Used battery-powered vehicles often sell for less than comparable cars with internal combustion engines, making them a good deal even before calculating savings in maintenance costs and fuel. That is expanding the number of people who can afford to buy such models.

Sales of used electric vehicles rose 40 percent in July from a year earlier, according to Cox Automotive, a research firm.

Depends if the pizza has dead animals on it or not

I am not so sure about that one. If your pizza has a 80 gram ham topping, and you drive four miles and back, I'd guess it is still the car use which weights heavier. Even if avoiding meat is better, of course.

Ultimately, one has to do the math. Carbon reduction is essentially a quantitative endeavour, and many outcomes when one actually measures and counts are counter-intuitive. For example, ship and truck transport of food over large distances can cost far less carbon than your car trip to the supermarket.
