Study: Global warming worsening watery dead zones

Study: Global warming worsening watery dead zones | Culture Collapse Disorder | Scoop.it

Global warming is likely playing a bigger role than previously thought in dead zones in oceans, lakes and rivers around the world and it's only going to get worse, according to a new study.

 

Dead zones occur when fertilizer runoff clogs waterways with nutrients, such as nitrogen and phosphorous. That leads to an explosion of microbes that consumes oxygen and leaves the water depleted of oxygen, harming marine life.

 

Scientists have long known that warmer water increases this problem, but a new study Monday in the journal Global Change Biology by Smithsonian Institution researchers found about two dozen different ways — biologically, chemically and physically — that climate change worsens the oxygen depletion...

Spring rains bring life to Midwest granaries but foster Gulf of Mexico 'Dead Zone'

Spring rains bring life to Midwest granaries but foster Gulf of Mexico 'Dead Zone' | Culture Collapse Disorder | Scoop.it
The most serious ongoing water pollution problem in the Gulf of Mexico originates not from oil rigs, as many people believe, but rainstorms and fields of corn and soybeans a thousand miles away in the Midwest.

 

Keynoting a symposium at the 245th National Meeting & Exposition of the American Chemical Society, the world’s largest scientific society, Nancy N. Rabalais, Ph.D., emphasized that oil spills like the 2010 Deepwater Horizon disaster, claim a terrible toll. Sometimes, however, they overshadow the underlying water pollution problem that has been growing more and more severe for almost 40 years.

 

“The Dead Zone is a vast expanse of water, sometimes as large as the state of Massachusetts, that has so little oxygen that fish, shellfish and other marine life cannot survive,” Rabalais explained. “The oxygen disappears as a result of fertilizer that washes off farm fields in the Midwest into the Mississippi River. Just as fertilizer makes corn and soybeans grow, it stimulates the growth of plants in the water — algae in the Gulf. The algae bloom and eventually die and decay, removing oxygen from the water. The result is water too oxygen-depleted to support life.”.. (Click title for more)
