Ancient Air Bubbles: Scientists May Have Discovered Cause of Low Atmospheric Oxygen Levels

Atmospheric oxygen levels may have decreased during the last 800,000 years due to glacial erosion. Studying air bubbles preserved in Antarctic ice for up to 1.5 million years have uncovered the likely cause of the depletion of oxygen in the atmosphere for not less than 800,000 years.

Air Bubbles Preserved in Antarctic Ice Highlights the Possible Cause of Low Oxygen Level

An unidentified culprit has been the cause of oxygen declines in our atmosphere for not less than 800,000 years. After analyzing the air bubbles stored in Antarctic ice for about 1.5 million years the likely suspect was caught. In the late Pleistocene, oxygen levels started to decline significantly, and it seems that glaciers may have been a factor, as per researchers.
