    Can I please buy some of that $2.90 per gallon gasoline?

      Cheap gas is half the reason we’re in this mess.

    I get confused by any other system than KMs per litre

      I wish that were used. But instead we get this inverse, L/100 km.

      Edit: after reading the article, apparently this is actually better. Even though km/L might seem easier to work with, it is misleading in terms of how you compare two vehicles.

    Good point, but GPHM has more syllables, and GPM makes it sound small;

    but still, maybe 50, 25, 15, and 10 MPG could be expressed as 0.02, 0.04, <0.07, and 0.1 GPM.

      Just drop the M - GPH/gallons per hundred is just as short and easy to say as MPG.
      In Australia we say “litres per hundred”, there’s no point specifying kilometres because what else would it be?

        “x ℓ/100”

        ​

        maybe.

        ​

        maybe “x mL/km” (“x milliliters/km”)—as in “80 mL/km”

        or

        maybe “x kL/Mm” (“x kiloliters/megameters”)—as in 0.8 kL or 800ℓ/Mm"

        ​

        I have to think about it. 🤔

    It’s why the 2007 Chevy Tahoe Hybrid won a green car award. It may have been a measley 21MPG city (11.2 L/100km, 4.8gal/100mi), but that was 30% better than previous models.

    Notably, the US DOE shows gal/100mi on their fuel economy website already. https://www.fueleconomy.gov/feg/bymodel/2007_Chevrolet_Tahoe.shtml https://www.fueleconomy.gov/feg/bymodel/2008_Chevrolet_Tahoe.shtml

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.
