Your task is to make two graphs each with time on the x-axis and temperature on the left-hand y-axis. The right-hand y-axis can be any other measurement, measurement by proxy, or estimate (CO2, insolation, etc.) for a similar time period. Then write a short paragraph for each graph that describes the relationship between the temperature and other parameter.
