The prediction that this season’s El Niño phenomenon will be stronger than normal has alarmed the Ecuadorian scientific community, which has warned of its impact on the flora and fauna of the Galápagos Islands.

Home to the highest concentration of species not found elsewhere on Earth, the archipelago is made up of more than 230 islands, of which only four are inhabited. It is located in the middle of the Pacific Ocean, 1,000 kilometres off the coast of Ecuador.

The climatic phenomenon occurs periodically and in the equatorial Pacific is characterised by an increase in sea temperature and intense rainfall. Its strength is determined by measuring the water temperature in that area and comparing it to the normal average. If it is 2 degrees Celsius above normal, it is considered “very strong”.

The sea temperature will be about 2.2°C above normal, according to the latest projection from the US National Oceanic and Atmospheric Administration (NOAA), which means that “the impact will be significant”, says Franklin Ormaza, a professor and researcher at the Faculty of Maritime Engineering and Marine Sciences of the Higher Polytechnic School of the Coast (ESPOL).

Will El Niño put Galápagos wildlife at risk?
