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.

Let me just travel 30km to the shops by foot and carry shopping home another 30km back again

Have you heard of this miraculous thing called public transit? And there are things called panniers which are pretty cool too.

But frankly, if you don't have groceries within walking distance, your neighborhood and your zoning laws are very poorly designed.

And that's deliberate. Neighborhoods around the world are designed to require cars to live in, because of oil company lobbying, and also for "security", in order to keep out people too poor to own cars.

Getting rid of cars requires changing the various ways our cities are designed to make cars necessary. That's worth doing too.

In this graph a bus would be a lot worse than a far given the massive size, aerodynamic brick wall, and constant stops.

Yeah but you have to divide the footprint by the average number of travelers.

Which in non city environments with high frequency is often only a handful to a dozen at most. Not that it matters, as this graph doesn’t show or or try to compare per person, only calories per vehicle mile.
