The earth’s climate has cycled between ice ages over the last two and a half million years. Ice cores drilled in Antarctica and Greenland evidence the relationship between greenhouse gasses in past atmospheres and temperature. As snow falls and is compacted, air is trapped in the ice. Scientists extract these trapped air bubbles to measure the percentage of greenhouse gasses present in the past atmosphere. By examining the oxygen and hydrogen isotopes in the ice cores it is possible to estimate the temperature at which ice was formed. The results show that CO2 and CH4 co-vary with temperatures over the past 400,000 years. This supports the theory that the carbon content in the atmosphere and global temperature are linked. When CO2 and CH4 increase, temperature rises and vice versa.
