The oxygen content in the world's oceans has decreased by more than two per cent in the past 50 years and could decrease by seven per cent by 2100, a new study shows.

The study, conducted at the GEOMAR Helmholtz Centre for Ocean Research in Keil, Germany, is being called the the first in-depth study of global ocean oxygen content, examining how global warming is impacting oceanic oxygen and why it is a concern.

After studying 50 years of data, researchers found the greatest volume of oxygen losses had occurred in the North Pacific, while the largest percentage loss was in the Arctic Ocean.

The main cause for the drop in oceanic oxygen is climate change, they say, specifically rising water temperatures.

Warmer water temperatures account for 15 per cent of oxygen loss, the researchers found, the majority from reduced stratification — when surface water doesn't sink to the ocean floor — caused by changing temperatures in the Arctic and the melting of sea ice.

It is serious matter, is it a climate change thing or just what happens on this planet in normal regular cycle. Who really knows

Added later: Astroids may not have only thing to wipeout life on this planet in the past.
