The Carbon emissions of the aviation and shipping industry is around 2-3% respectively. Railways are like 0.7%. Most of the world's transportation emissions are from road transportation - cars and trucks.
In fact the amount of aviation oil demand in the US has declined for 50 years straight. So efficiency gains have outpaced demand growth. Although the demand for aviation oil has probably increased globally.
Half of the climate change impact of aviation comes from contrails and not the fuel consumption. That's the lowest hanging fruit in that sector and Google is already working on that.
I can see why you might be confused by the impact of aviation and the disproportionate attention the media gives the subject. This is because the media wants to blame carbon emissions on the 1% and not the lives of Middle class people. Most of the world's emissions comes from middle class stuff like electricity demand, steel, cement, road transportation, heating and livestock production.
Fortunately we might be on a good tragectory. Coal demand peaked 10 years ago. It will starting decline rapidly soon as India and China deploy a fuck tonne of solar and batteries. Oil demand will probably peak in 2027. ICE vehicle sales already peaked in 2017. We will probably hit peak emissions in 2025.
"Most of the world's emissions comes from middle class stuff like electricity demand, steel, cement, road transportation, heating and livestock production." Again, not entirely true. For example, in the U.S., "The top income decile emits 34% of energy-related CO2, and when we include the next decile, 17%, we see that the top 20% of earners emit more than 50% of the energy-related CO2." https://briefedbydata.substack.com/p/co2-emissions-are-an-inequality-problem
These are also questionable predictions: "Oil demand will probably peak in 2027. ICE vehicle sales already peaked in 2017. We will probably hit peak emissions in 2025."
In the future, I will look into aviation-related emmions, but you might consider not starting comments with "You're wrong on many levels."
I think you are missing my point. On its own, air travel isn't a big impact on climate change, but this is yet another example where we are using more energy. The bottom line is that to reduce emissions we have to reduce some things, and so far society is unwilling to reduce much of anything. Hence, as I noted in an earlier replay, we continue to increase our use of fossil fuels.
Huh. I was not aware there was a post covid boom in coal demand. My guess my metric would have correct 5 years ago when I first heard it. As far as I know China accounts for 50% of global coal demand. Coal demand is likely to fall significantly in coming years there.

"Coal demand peaked 10 years ago." Nope, coal, like all fossil fuels, is still increasing. https://briefedbydata.substack.com/p/world-energy-consumption

My main point still stands - aviation is unlikely to make a significant impact on climate change.

You're right on the second point.
