Right-wing chortling, cont.

Har har har. Stupid environmentalists.

If this theory holds up, it means that global warming and the build-up of heat-trapping gases are bringing about oceanic changes beyond those previously documented: a rise in sea level, more acidic ocean water and the bleaching of coral reefs.

Low-oxygen dead zones, which have doubled in number every decade and exist around the world, have a variety of causes....

What's happening off Oregon, scientists believe, is that as land heats up, winds grow stronger and more persistent. Because the winds don't go slack as they used to do, the upwelling is prolonged, producing a surplus of phytoplankton that isn't consumed and ultimately dies, drifts down to the seafloor and rots.

"It fits a pattern that we're seeing in the Benguela Current," said Andrew Bakun, a professor at the University of Miami's Pew Institute for Ocean Science who wasn't part of the Oregon study. "It's reasonable to think these hypoxic and anoxic zones will increase as more greenhouse gases build up in the atmosphere."

See, nothing to worry about. It's just the oceans running out of oxygen. Stop being such an alarmist.
