Recorded sources
0 sources for · 9 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that evaporative coolers work in humid climates?

No. Multiple reference and peer-reviewed sources state that evaporative coolers are not suitable or effective in humid climates, since the air is already saturated and adding moisture does not cool. Some sources note only desiccant-assisted or hybrid systems work in humid conditions.
