Coral reef research has focused on the twin evils birthed by record-high greenhouse gas emissions: warming oceans and increasingly acidic seawater. These global threats are caused by seawater absorbing the excess heat and carbon dioxide that fossil fuel burning has added to the atmosphere. But there is another consequence that is seldom discussed.
