Abstract

Scientists have discovered the oldest ice ever found, dating back 6 million years, in Antarctica. The ice contains air bubbles from the Pliocene epoch, a time before the ice ages when the Earth was warmer and carbon dioxide levels may have been as high as they are today. Initial analysis of the bubbles suggests that CO2 levels were low during the late Pliocene and only slightly decreased as the ice ages began. This discovery provides valuable insights into Earth's ancient climate and the potential impact of even small changes in CO2 levels. [Extracted from the article]
