Chemical reactions require a certain amount of energy. Cool and temperate are easy ways of saying that there's less heat energy available.
If you're wondering about tropical islands... salt and moisture are corrosive, no matter what the temperature. Heat just allows the salty spray to do its work far more quickly. Water and salts are some of the most reactive substances on earth, they love to get tangled up in other molecules. When the oxygen in air or water combines with something else, like iron, we usually call it rust.

Corrosion occurs with a combination of different metals. The metal that is highest on the electron scale will be the anode and the other is cathode.
