🚨 Paper Alert!
In 2023, Mexican coral reefs experienced an unprecedented bleaching event.
But bleaching wasn’t the biggest issue.
Our study in Proceedings B @royalsociety.org shows a marine heatwave caused massive coral mortality and pushed reefs from production to net erosion

El Niño 2026 is now bleaching corals that returned after 2023.
The 2023 heatwave killed most corals in the Mexican Pacofic. New colonies became established. They’re turning white before recovery can take hold #ENSO

A new study by López-Pérez and colleagues shows a two-decade decline in skeletal density of Pocillopora corals in the Mexican Pacific tied to rising temperature, lower pH, and aragonite saturation, highlighting reef vulnerability under climate change.
Two decades of skeletal density decline in Pocillopora spp. corals in the Mexican Pacific Ocean: Insight into a tropical eastern Pacific acidification scenario?
Corals demonstrate vulnerability to environmental changes, exhibiting the capacity to substantially modify coral calcification. In this study, we estimated declines in the density of Pocillopora…

Heard of "Darwin's paradox"? It refers to Charles Darwin's observation that coral reefs are wildly productive despite occurring in nutrient-poor tropical oceans. Reefs are, so the story goes, oases in marine deserts 🏝️...
Turns out that 2/3 of these assertions are very wrong...
