"Oi, why is Singapore so hot?" I don't recall when my brothers first started asking me that question, to be honest. I do, however, remember this single question being repeated incessantly during any occasion that we were outdoors while growing up in Singapore. When we were eating our weekly chicken rice lunches, or when playing football, or after we escape the heat (and deluge of humidity) by dashing indoors into the air-conditioned comfort of a shopping mall. ---------------
