While no two El Niños are identical, stronger events — including outbreaks in the early 1980s and in 2015-16 — tend to produce predictable outcomes. They can pressure agricultural production, energy markets and global shipping routes while increasing the threat of disease outbreaks. Even before the El Niño declarations this week, its effects had been felt across several regions, including a delayed start to India’s monsoon season and a temporary halt to Peru’s anchovy fishing season.
