4th global coral bleaching event underway due to high ocean temperatures, exacerbated by climate change, affecting reefs worldwide.

The fourth global coral bleaching event is underway, affecting reefs worldwide due to unusually high ocean temperatures. Scientists warn that recovery is becoming more difficult as climate change leads to more frequent and intense marine heatwaves. Coral reefs, which support millions of people through their contribution to fish protein and nurture around a quarter of ocean species at some point in their life cycles, are crucial for coastal communities that depend on them for food and livelihoods. The annual economic value of the world's coral reefs is estimated at $2.7 trillion.
