Looks like trains are about 50wh/km

I couldn't find any info on planes, but that'd be interesting to see how massive that would be too.

It's that normalized by passenger or is that just the train?

[-] federalreverse@feddit.de 16 points 3 months ago

Normalized by passenger, certainly. However, it's easier to hit passenger capacity in a train than in a (private) car.

[-] huginn@feddit.it 3 points 3 months ago

Wait the private car isn't normalized as 1 person per car or 1.2 average people per car?

Deeply suspicious framing if that's the case.

[-] federalreverse@feddit.de 2 points 3 months ago

You misunderstood me. For one, I simply assumed that locomotives have big engines for a reason and thus the number can't be calculated for the entire train. For two, when I mentioned the capacity of cars, I meant maximum passenger capacity. I said that because at maximum passenger capacity, cars become a reasonable means of transportation whereas normally, they are ridiculously inefficient.

So if you just 4 people in an electric car then it beats a train? Huh

The 50 is normalized to passenger. I think it's 30 per seat, but I guess they don't fill all the seats usually.

Climate - truthful information about climate, related activism and politics.

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.
