This lacks scientific models or sources that quantify the magnitude of the reduction in ship tracks and the resulting impact on sea temperatures. They are not in the science.org article[1] he links either.

Usually posts with little evidence and the use of the phrase "may be causing" result in flagged posts, but not when it fits a certain narrative?

It still lacks scientific models, though it is too recent a phenomenon for us to have an accurate modelling. Even then, in the last three years we had La Nina which kept the temperatures cold, while this year it's el Nino which is increasing the effect.

Leon Simons presented his findings in front of aerosol society.

I also wanted to ask, what is the certain narrative it fits?

Towards the end of that article were links to a few studies. Here's the first linked study I found: https://www.nature.com/articles/s41586-022-05122-0

That study says little about fewer ship tracks causing sea warming and nothing about the magnitude of any possible sea warming.

If you'd made it through the abstract you would have read how ship tracks cause cooling.
