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.

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?
The 50 is normalized to passenger. I think it's 30 per seat, but I guess they don't fill all the seats usually.
Normalized by passenger, certainly. However, it's easier to hit passenger capacity in a train than in a (private) car.
So if you just 4 people in an electric car then it beats a train? Huh
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.
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.
