Records of past climate change from human measurements (e.g., thermometers, rain gauges) typically go back < 150 years. These time scales are too short to examine climatic variability on geologic time scales.   For this reason, Earth Scientists use trees, corals, sediments and glaciers to study fluctuations in climate going back hundreds and thousands of years.

Earth Scientists in MEAS work with colleagues to understand the integrated Earth, Marine and Atmospheric System.
