Oxygen drain will be apparent in oceans by 2030s

Climate models suggest climate change is slowly sapping oxygen from the world’s oceans. In some places, declining oxygen levels are already discernible, but in most oceanic regions, scientists struggle to differentiate between climate change-related losses and natural fluctuations.

A new model, developed by researchers at the University Corporation for Atmospheric Research, suggests scientists’ differentiation difficulties won’t last much longer. By the 2030s, oxygen losses caused by climate change will be widespread and readily apparent.
