Climate Change is impacting the world and the oceans are facing the worst condition as indicated in the new study by the International Union for Conservation of Nature (IUCN). The new study says that climate change and the increasing temperatures of the oceans have reduced the amount of oxygen available into oceans by 2 percent between 1960 and 2010.
The study also shows that the oxygen levels in some of the tropical regions have dropped by up to 40 percent and scientists have said that a slight more decline in the percent will be irksome for big, energy-dependent fish like marlin, sharks and tuna. Low oxygen levels will drive them to shallow water which will raise concern over a risk of overfishing.
The IUCN report also said that this could upset delicate ecological balances by favoring sealife tolerant of low oxygen, like microbes and jellyfish. Even “basic processes” on Earth like the cycling of nitrogen and phosphorous could suffer and it also reports that nutrient pollution from farming and other sources is also a problem on coastlines.
This finding adds another remark to the future that could be affected due to climate change.
