• In this watercolor and colored pencil piece, scientist and artist Jill Pelto, depicts tree rings, ice cores, and lichens, all of which help scientists reconstruct past climates. 
• The artwork introduces students to paleoclimatology, the study of the Earth's past climate and average global temperature using natural materials, fossils, or elements. 
  

Positives

• This watercolor and colored pencil piece will show students the importance of reconstructing past climates so that scientists understand how the environment responds to climate variability.
• The red line depicting the average global temperature is a simple and effective visual for the recent rapid increase in global temperature.

Additional Prerequisites

• Students should be familiar with proxy data and their function in determining past climates.

Differentiation

• Earth science classes could read the reference article about how proxies are used to infer past climate and then have a class discussion on climate proxies.
• Students could conduct a research project on the different kinds of proxies that can be used to estimate past temperatures on Earth.
• Other resources on this topic include this activity on using ice cores to learn about past climates and this lesson on analyzing tree rings to learn about past climate conditions.
