Climate change is going to wreak havoc on the world’s oceans, according to two new studies, depleting the warming waters of the oxygen that fish and other sea life depend on to survive. By 2080, around 70 percent of the oceans on the planet will suffer from a lack of oxygen due to warmer temperatures, a study published in November by researchers with the American Geophysical Union’s journal Geophysical Research Letters concluded. The study finds that substantial deoxygenation of the middle ocean depths, where a large percentage of the fish that people eat are found, began occurring in 2021. The reason for the declining oxygen levels in oceans is that warmer waters hold less dissolved oxygen and ocean temperatures are rising at an alarming rate. According to another new study released this week and published in the scientific journal PLOS Climate, a majority of the world’s ocean surface has consistently exceeded the normal range since 2014.
