Theory 54/Tropical Rainforest/Fire
Rainforest Fire Is Drought Against Fuel
The claim
Fire enters tropical rainforest when the ratio of drought severity to fuel connectivity exceeds a threshold, so a dry year with fragmented fuel still does not burn.
01Mechanism
Humidity resists ignition while fuel carries it; both must be favourable, which is why rainforest fires are rare and episodic.
02Prediction
Fire occurrence should track the ratio.
03Refutation
Fire tracking drought alone would remove fuel.
