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 compact SUVs now create less pollution, on average, than sedans, thanks to the rapid rise of small electric SUVs. (wapo.st)

The picture would of course look very different if manufacturers had chosen to make smaller inexpensive electric sedans.

To clarify, I find your reply unhelpful, because you explain the logical course of action for an individual to make the most of the current sorry state of western transport. US transport, to be specific.

And in reply to something obviously rheotorical.

Your answer is not even close to the most efficient solution to transport we might come up with as a society.

Meanwhime I am commenting about that hopelly improved future, where owning a car in the first place is no longer a choice made for you.

Where you can head out, and get to any point on the map for a reasonable cost, in a timely manner, while owning nothing more than the clothes you'd be wearing.

I literally live in a country where that is how it works. It's possible.

And I live in a country which As a Society just decided, by popular vote, to elect someone with the explicit goal of devolving what little remains of our sorry little public transport, and which promises a fight for our communities to hold one to what little we can, so yes, I gave an individual answer, because as a Society the answer is demonstrably“Drill baby, Drill” and “climate change is a hoax”.
