Kiribati Sees 10% Coral Bleaching as El Niño Warms Seas by 2C

2 articles · Updated · The New York Times · Aug 13

Around Christmas Island in Kiribati, about 10% of corals appeared bleached in dives over the past few days as an early El Niño takes hold.
Sea-surface temperatures there are already 2 degrees Celsius above the 30-year norm for this time of year, prompting researchers to deploy sensors tracking heat, salinity and reef stress.
Alyssa Atwood of Florida State University said the bleaching is likely to worsen through the end of 2026 because the El Niño now underway has not yet peaked.
Bleached corals can recover if waters cool, but prolonged heat can kill them, leaving Kiribati exposed early in what is expected to be one of the strongest El Niño events on record.

2026 Kiribati Coral Bleaching Emergency: El Niño, Climate Change, and the Fight to Save Pacific Reefs

Overview

In August 2026, Kiribati faces a severe coral bleaching crisis as a powerful El Niño and ongoing climate change drive ocean temperatures around Christmas Island to record highs. This rapid warming causes corals to bleach and die, threatening the region’s reefs and the communities that depend on them for food and protection. Past events show that pristine, well-managed reefs can recover, but rising global temperatures and local pollution make this harder. As tuna migrate away due to warming seas, Kiribati’s economy and food security are at risk. Active local conservation and urgent global climate action are essential to protect both reefs and livelihoods.
