In a paper published in Nature Climate Change, Ove Hoegh-Guldberg, director of the Global Change Institute at the University of Queensland, together with Greg Rau of the Institute of Marine Sciences at the University of California, and Elizabeth McLeod of The Nature Conservancy, say new tactics are needed to save oceans from CO2 emissions.
“It’s unwise to assume we will be able to stabilise atmospheric CO2 at levels necessary to prevent ongoing damage to marine ecosystems,” Professor Hoegh-Guldberg said.
“In lieu of dealing with the core problem – increasing emissions of greenhouse gases – these techniques and approaches could ultimately represent the last resort.”
In addition to using shade cloth over coral reefs, the paper suggests novel marine conservation options, including applying low-voltage electrical current to stimulate coral growth and mitigate mass bleaching; adding base minerals such as carbonates and silicates to the ocean to neutralize acidity; and converting CO2 from land-based waste into dissolved bicarbonates that could be added to the ocean to provide carbon sequestration.
