During the 1950s, Danish scientist Willi Dansgaard discovered that rain carries a record of the temperature at which it fell. Dansgaard realized he could read temperatures deep into the past by studying the chemical makeup of ice core samples.
This video introduces Dansgaard, Camp Century in Greenland, and the science behind studying ice core samples.
I storyboarded, created the assets and animated a series of segments for the longer video.
