Climate Change: Causing Huge ‘Dead Zones’ in Oceans by 2030

Man-made climate change is extremely threatening to the environment around the world. 97 percent of actively publishing climate scientists agree: Climate-warming trends over the past century are extremely likely due to human activities. Studies show that man-made climate change is already decreasing the oxygen levels within some parts of the world’s oceans, and by 2030 huge “dead zones” could start to appear.

The oxygen levels are declining because the increasing water temperature makes it difficult to absorb and distribute the oxygen. If carbon emissions continue at this rate, it will likely result in falling oxygen concentrations across large areas of the oceans. A decrease in carbon emissions is going to be a nearly impossible task to complete; everyone in the world will need to change how they go about their daily lives.

Environments around the globe are being effected on different levels by climate change. The Arctic, for example, has temperatures that are rising at twice the rate as they are across the planet as a whole. The process has already begun within the Atlantic Ocean, and the Pacific Ocean is likely to see large sections with reduced oxygen by 2030.

“Dead zones” are a huge problem for humans and the environment. These areas could pose a great threat to some forms of marine life at depths of 200 meters or more, which in turn poses a threat to us. We rely on the marine ecosystem for a variety of services – one of them is a food supply. "We rely on bottom fisheries in these areas. Our study was essentially on fish food," Levin said. "Species that form structures that provide biodiversity-sustaining habitat on the sea floor might be important to watch for susceptibility to ocean deoxygenation, acidification, and warming. They are also vulnerable to human disturbance."
