A reading that explains how the analyses of hydrogen and oxygen isotopes from ice cores determine past temperatures on Earth.
Students will learn how isotopic ratios of hydrogen and oxygen in water molecules from the ice-cores can be used to infer temperature variations in the past on Earth.
Use this tool to help students find answers to:
- How are isotopic ratios from ice cores used to calculate past temperatures?
- Which isotopes of hydrogen and oxygen are used to compare against a standard to draw inferences about temperature variations in the past?
