El Niño 2026-27 as a polycrisis: What happens when health and energy systems fail simultaneously?

the gist

A 'super' El Niño is developing in the tropical Pacific. NOAA puts the chance of strong to very strong conditions during January to March 2027 at more than 83 percent. El Niño is a natural climate phenomenon, but it shifts weather worldwide and can bring more extreme heat, drought and flooding on top of climate-driven extremes. Earlier major events in 1982-83, 1997-98 and 2015-16 were followed by severe consequences. The concern is a 'polycrisis': heat could strain power grids just as hospitals are flooded with patients, so failures in energy and health systems would compound each other.

so what

Planning for each hazard alone isn't enough when disasters hit simultaneously, so health and energy systems need to be prepared together.

fun fact

El Niño is Spanish for 'the boy' and was named by Peruvian fishermen who noticed warm water around Christmas.
