Climate change and dead zones
Abstract Estuaries and coastal seas provide valuable ecosystem services but are particularly vulnerable to the co‐occurring threats of climate change and oxygen‐depleted dead zones. We analyzed the severity of climate change predicted for existing dead zones, and found that 94% of dead zones are in...
