Theory 10/The rival is a different mechanism/Urban climate
Sky View or Waste Heat?
The claim
Urban heat island intensity follows sky-view factor because geometry controls radiative loss.
01The rival explanation
Dense districts also release more anthropogenic heat from traffic and cooling, so geometry is incidental.
02What would tell them apart
Anthropogenic heat peaks during working hours; radiative loss dominates at night.
03Prediction
The sky-view relationship should be strongest nocturnally.
04Refutation
If the relationship is equally strong by day, the rival wins.
