For example, as water warms it holds less dissolved oxygen than cooler water.

As a result, the world’s oceans, coastal seas, estuaries, rivers and lakes are undergoing a process known as “deoxygenation.”

When dissolved oxygen levels fall to about 2 milligrams per liter – compared to a normal range of roughly 5 to 10 mg/L – many aquatic organisms become severely stressed.

Scientists call this low oxygen threshold “hypoxia.”
