Oxygen loss could be a huge issue for oceans

A major study into an ancient climate change event that affected a significant percentage of Earth's oceans has brought into sharp focus a lesser-known villain in global warming: oxygen depletion.
The study, just published in the prestigious Proceedings of the National Academy of Sciences, examined a past period of global warming around 94 million years ago, when oceans became de-oxygenated.
This famous period in Earth's geological history, known as an Oceanic Anoxic Event (OAE), was more severe and on much longer timescales than the current changes. But it has given the scientists studying this period an extreme case-study to help understand how the oceans are effected by high atmospheric CO2 emissions.
