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:
How much each change to the atmosphere has warmed the world:
Recommended actions to cut greenhouse gas emissions in the near future:
Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

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?
OPM (Ounces per mile) seems to work out to nice numbers. A gas guzzler might use 13 OPM, where as a decently efficient sedan would be around 3. Plus we can keep our ridiculous American units, just the way we like them.
I was doing the metric equivalent.
The problem is mLs and ounces sound too small.
The good thing about 100 is that in turns mLs and ounces into liters and pounds, or gallons, as the case may be;
but that 100—I like units more than x-number-of-units as the basis of expression.
Nonetheless, I guess its GPHM, LPHKM, GPH, and LPH, until we come up with something better.
Then we have wp:natural gas vehicles and wp:miles per gallon gasoline equivalent, as LNG, CNG, and electric will probably become more common.
If 33.40 kilowatt-hours/mile ≈ 74.71 Mj/km
then if an electric car had an MPG equivalent of 40,
it'd be 0.835 kilowatt-hours/mile ≈ 1.87 Mj/km
Yeah, I was thinking about the same sorts of things. I think ounces are okay but not great. I cook a lot and have a good intuitive grasp on fl oz, but I’m not sure everyone does here. I wish we had a good unit bigger than miles/kilometers to use with liters/gallons. Leagues are still too small and megameters are too big, but both of those have the advantage of sounding awesome… and disadvantage of not being commonly used.
"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. 🤔
