Oceans losing oxygen; West Coast affected early

eats shoots 'n leaves

Deoxygenation due to climate change is already detectable in some parts of the ocean. New research finds that it will likely become widespread between 2030 and 2040. Other parts of the ocean, shown in gray, will not have detectable loss of oxygen due to climate change even by 2100.

The oceans are losing oxygen, and climate change is the culprit.

Areas earliest hit are the western coasts of North America and Africa and the northeastern coast of South America.

The result will be major shifts in marine life, including the development of major dead zones.

And given that much of the world depend son ocean fish for protein, the changes could portend serious human and political crises.

From the American Geophysical Union:

A drop in the amount of oxygen dissolved in the oceans due to climate change is already discernible in some parts of the world and should be…
