Climate change: Causes of Unprecedented Temperatures Rise World’s Oceans Are running out of Oxygen Rapidly
-Rahil Khan
We have been alarmed many times about the crisis that human civilization is going to face due to climate change. But this time, scientists brought about surprising information about a new crisis. Scientists say that due to climate change, the Oxygen concentration in the ocean is rapidly decreasing. As a result, several marine fish are feared to disappear in the near future.
After a long study, the International Union for Conservation of Nature (IUCN) published this report when COP25 was being held in Madrid, Spain. It is one of the great studies of the history of the sea.
IUCN’s research also shows that due to climate change, not only oxygen but also the amount of protein, vitamins, and minerals in seawater is constantly decreasing. Researchers have found oxygen deficiency in 700 locations around the Seas and Oceans.
In 1960, a similar study was conducted and then Oxygen depletion was found at 45 locations in the oceans. Those cultivating near the coast use different pesticides in their field. These pesticides are rich with Nitrogen and Phosphorus, a part of which generally drain into the sea.
This is the main cause of reducing the amount of oxygen in the seawater, according to the study. Also, in recent times climate change is accelerating oxygen shortages.
The IUCN study also says that the seawater is also being affected due to a continuous increase in carbon dioxide (CO2) in the atmosphere. As the temperature of the sea surface is being increasing day by day, the seawater temperature is also increasing duly. Scientists say that oxygen concentration is lower in hot water.
However, if oxygen is low in the water, it doesn’t mean that all fish are in harm. Oxygen is a major problem for fishes that swim fast. On the other hand, the temperature at sea is now ideal for jellyfish.
IUCN official Minna Epps said, “We are being heard that the Oxygen is decreasing in the ocean. But the situation is come down so degraded not been thought before this research is conducted.
