Oxygen is Disappearing from Earth’s Atmosphere

Researchers from Princeton University have recently completed analyzing Pleistocene Epoch ice cores from Antarctica and Greenland. From thirty years of data, they have created a record of atmospheric oxygen levels spanning the last 800,000 years. They built their research timeline by using measured rates of oxygen-to-nitrogen found...
