Adugna Woyessa was a little boy the first time drought tore his country apart. As harvests failed in rain-starved regions of Ethiopia in the early 1970s, and his school turned a classroom into a grain store for farmers to send aid, he had no idea that scientists were beginning to connect the force parching its fields with cyclical shifts in trade winds that had long supercharged violent weather from South America to Australia.

The now notorious El Niño – Spanish for “little boy” – was named by fishers in the Pacific in the 1800s, but it was not until the 1970s that scientists understood its global nature and began to piece together the historical impact of the natural weather pattern characterised by hot years and brutal extremes.
