Ocean dead zones will expand as CO2 asphyxiates deep-sea animals

Low-oxygen “dead zones” in the ocean could expand significantly over the next century, according to marine chemists. These predictions are based on the fact that, as more and more carbon dioxide dissolves from the atmosphere into the ocean, marine animals will need more oxygen to survive. Concentrations of carbon dioxide are increasing rapidly in the […]

Dramatic expansion of dead zones in the oceans

(University of Copenhagen) Unchecked global warming would leave ocean dwellers gasping for breath. Dead zones are low-oxygen areas in the ocean where higher life forms such as fish, crabs and clams are not able to live. A team of Danish researchers have now shown that unchecked global warming would lead to a dramatic expansion of […]
