I don’t disagree with you on future energy abundance. I too am an optimist. Renewables and Nuclear are a thing.

All I’m saying is that if we continue at this rate of carbon emissions, even only 10years, nevermind 30years (the time to develop and scale zero emissions planes, which has barely started) the planet will definitely see changes that won’t be nice. We are talking “Areas hosting 1B people today will see unsurvivable wet-bulb temperatures more than 100 days each year”. Mass migrations won’t be pretty.

The choice we are facing for the next 20 years is: Prepare your low carbon energy transition HARD, or prepare some damn solid walls around your country.
