Earth’s Most Profound Climate Change Occurring in the Oceans –“Drastic Loss of Oxygen”

Oceanographers from GEOMAR Helmholtz Centre for Ocean Research Kiel just published the most comprehensive study on global oxygen content in the world’s oceans so far in the journal Nature, showing that the ocean’s oxygen content has decreased by more than two percent over the last 50 years.

Climate change models predict the oceans will lose oxygen because of several factors. Most obvious is simply that warmer water holds less dissolved gases, including oxygen.

Another factor is the growing stratification of ocean waters. Oxygen enters the ocean at its surface, from the atmosphere and from the photosynthetic activity of marine microorganisms.
