Carbon dioxide and global warming

  • Exhibition Text

    • The amount of carbon dioxide (CO2) in the atmosphere is related to global temperature: as the Earth warms, CO2 increases, and vice versa. Measuring CO2 in ice cores provides a record of atmospheric CO2 variation over thousands of years — from one glacial period to another. By tracking the natural variability of CO2, scientists have discovered that the recent rise in atmospheric CO2 has been caused by human activities.
