Warming Stripes (State)

Ask a Question

  • This collection of graphics displays long-term temperature trends for each state using a color gradient.
  • Each colored stripe represents one year, with blue indicating a year cooler than average, and red indicating a year warmer than average.
Teaching Tips


  • Students can easily visualize warming temperatures using these simple and engaging graphics.
  • Images can be downloaded for offline use.

Additional Prerequisites

  • The entire site is available in Spanish by clicking the ES button on the right side of the page.
  • The images are based on the original warming stripes graphics by Ed Hawkins.
  • This data uses the 20th-century average as the standard reference for the temperature anomalies.


  • These graphics can be used in science classes to visualize the warming trends of a state and compare trends between states.
  • Elementary science teachers could use these images to introduce the idea of warming temperatures in their state. The images are colorful and easy to understand, which will make them great resources for younger ages.
  • Cross-curricular connections can be made with art or design classes by challenging students to come up with their own compelling visuals that display climate data.
  • Warming Stripes are some of the most common climate data visualizations and have been used around the world to raise awareness of global temperature increases. Students can discuss why these images are so effective and compelling. Additionally, students can research how these graphics became popular and the different ways they have been used.
  • Other similar resources include this interactive U.S. map displaying daily temperature anomalies, NASA's temperature tracker, and this math lesson plan where students assess temperature trends for their city.
Scientist Notes
This resource depicts extremely hot periods in US states from 1895-2021, smoothened using records of average temperature anomalies from 1901-2000. The stripes are an effective tool to create awareness of the implication of rising average temperatures and the urgent need to address climate change. This resource is recommended for teaching.
