From a climate change/fisheries/pollution/habitat destruction point of view, our nightmare is here, it’s the world we live in.”
This bleak statement about the current status of the world’s oceans comes from Dr Wallace Nichols, a Research Associate at the California Academy of Sciences. Al Jazeera asked Dr Nichols, along with several other ocean experts, how they see the effects climate change, pollution and seafood harvesting are having on the oceans.
Their prognosis is not good.
Dr Nancy Knowlton is a marine biologist at the Smithsonian Museum of Natural History in Washington DC. Her research has focused on the impact of climate change on coral reefs around the world, specifically how increasing warming and acidification from carbon dioxide (CO2) emissions have affected oceans.
While she is unable to say if oceans have crossed a tipping point, Dr Knowlton offered this discouraging assessment, “We know it’s bad and we know it’s getting worse, and if we care about having coral reefs, there’s no question we have to do something about CO2 emissions or we won’t have coral reefs, as we do now, sometime between 2050-2100.”
Since at least one quarter of all species of life in the oceans are associated with coral reefs, losing them could prove catastrophic.
