Gallery: Aquatic Dead Zones Produce Greenhouse Gas 300X More Potent Tha...


We’ve heard a lot lately about the relationship between global warming and the ocean. An article in Thursday’s Journal of Science describes how aquatic dead zones — or hypoxic waters — create trouble for more than the organisms that live in the waters. In addition to their low levels of oxygen killing off marine life, they can also increase global warming. University of Maryland Center for Environmental Science oceanographer Dr. Lou Codispoti explains in his article how waters with depleted oxygen create high levels of Nitrous Oxide which can seep into the atmosphere and add to the greenhouse gas effect.

Surely they should base any assumptions on things that can be measured, such as a rise in sea levels. After all, surface temperatures go up and down, but the rise in sea levels reflects both melting ice and thermal expansion.
