  • There are scientists who study ice cores. Every summer a bit of ice in the north pole melts exposing liquid water to the air and interacting with it. Every winter that liquid freezes again. What we are left with are layers of ice that have been frozen in different years. These layers go back thousands of years. With our knowledge of atomic physics, we know what kind of isotopes exist in the atmosphere at certain temperatures. With this knowledge we can calculate the temperature of the earth in years past. We can also measure the amount of CO2 in the atmosphere that was present in the past. With this information we have found the is a direct relation to the temperature of the earth and the amount of CO2 present in the atmosphere.

    I am sure someone can explain this better than me, but this is the jist of it.
