What am I looking at?

Ships burn fuel; sulfur in the exhaust seeds clouds with extra droplets.
Bright cloud lines are ship tracks — more, smaller droplets reflect more sun (the Twomey effect).
Sun sparks bounce off bright tracks (cooling ✓) or reach the dark ocean (warming).
Sea color = temperature: indigo is cooler than 2019, deep blue is the baseline, and warming walks it through teal and green toward hot yellow-green. A big sprayer fleet can cool it below baseline.
IMO 2020 lever: the real-world rule cut fuel sulfur 3.5%→0.5%. Tracks collapsed; hidden warming emerged.
Sprayer boats are marine cloud brightening — proposed deliberate track-making with sea salt.
Meters are toy-scaled to real published magnitudes, not a climate model.
