Climate Change Main Cause of Global Coral Bleaching

Climate Change Main Cause of Global Coral Bleaching

A new study shows that climate change, not just natural events like El Nino, is the main cause of coral bleaching.

Coral bleaching happens when the ocean gets too warm, and the corals lose their colorful algae.

This study looked at big bleaching events from 1998 to 2025 and found that human-caused climate change makes these events more likely and widespread.

Without climate change, bleaching would be rare.

The study also found that in the future, climate change will still be a bigger risk for coral reefs than El Nino.

Many people and countries depend on healthy coral reefs for food and jobs, so reducing emissions is crucial to save them.
