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 in Antarctic ice suggest that glacial erosion caused atmospheric oxygen levels to dip over the past 800,000 years.
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.
An unknown culprit has been removing oxygen from our atmosphere for at least 800,000 years, and an analysis of air bubbles preserved in Antarctic ice for up to 1.5 million years has revealed the likely suspect.
