I’m not saying this is wrong because I don’t know shit but when ships crossing the Atlantic were forced to switch to low sulfur fuel a few years ago the North Atlantic rose in temp a few degrees. Turned out the sulfur in the exhaust was causes clouds to form in the atmosphere and was shading the ocean and masking global warming in that region. Pretty much the opposite effect of what you’re saying this dude is claiming.
Speaking with my limited knowledge, there apparently are cooling contrails and warming contrails, but the warming ones are more common. I don’t know why or when the contrails are cooling or warming.
