> I'm not sure why you are lumping those two modes of transport together.

I think you misunderstand - "commercial flight" is referring to flying on one of the large carriers instead of privately. Both of those modes of transportation move large groups of people, together. Many people, one trip. Rail is available in Europe, but not in the US.

> Perhaps the reason it is not high on people's lists of things to fix, though, is that "the aviation industry only contributes around 2% of global CO2 emissions, with private air travel representing an even smaller fraction."

They are saying this is an "emergency" though. Is it a good idea to fly any plane during a climate emergency that will purportedly starve all of us? Why aren't these people concerned about starving themselves? This is an emergency and they aren't taking their own precautions seriously.
