The deadly trio-- global warming, acidification, and reduction in oxygen levels-- poses greater threat to oceans around the globe.

Reuters reported on Thursday an international study saying that though the rise of temperature is slower than before, the oceans are continuously warming and thrusting commercial fish stocks to the poles thus increasing the risk of extinction of some marine species.

Heat that forms from greenhouse gases in the air makes the oceans warm. When the carbon dioxide in the atmosphere mixes with the sea water, the reaction produces a weak acid. Lastly, the decrease in the oxygen levels in the water was also observed due to the blooms of algae coming from the sewage and the fertilizers flowing into the oceans.

The International Programme on the State of the Ocean (IPSO), a non-governmental group of leading scientists, told Reuters, “Risks to the ocean and the ecosystems it supports have been significantly underestimated. The scale and rate of the present day carbon perturbation, and resulting ocean acidification, is unprecedented in Earth's known history.”

The very same scenario involving the ocean also occurred 55 years ago which led to the extinction of numerous species. Furthermore, the rate of changes that we have now is much faster than before.

The Global Ocean Commission insisted on stronger implementing actions.

Trevor Manuel, co-chair of the commission and minister in the South African Presidency, told Reuters, "If the IPCC report was a wake-up call on climate change, IPSO is a deafening alarm bell on humanity's wider impacts on the global ocean.”

According to reports of the U.N.'s Intergovernmental Panel on Climate Change (IPCC) last week, the percentage of the probability that the human race contributed to global warming has increased to 95 percent from 90 percent in the year 2007.

Alex Rogers of Oxford University, scientific director of IPSO, said, "We are seeing impacts throughout the world.”
