Modern thermometers were invented in the 1700s. Barometers were invented in 1600s. To learn about climate in more ancient times, scientists must look for clues in the environment. Climate changes are recorded in Antarctic ice sheets, sediments on the ocean bottom, rock formations growing in caves, and more.
