PETM: Unearthing Ancient Climate Change

American Museum Natural History

In this video, a team of paleontologists, paleobotanists, soil scientists, and other researchers take to the field in Wyoming's Bighorn Basin to document how the climate, plants, and animals there changed during the Paleocene- Eocene Thermal Maximum (PETM) when a sudden, enormous influx of carbon flooded the ocean and atmosphere for reasons that are still unclear to scientists. The PTEM is used as an analog to the current warming occurring. The scientists' research may help inform our understanding of current increases in carbon in the atmosphere and ocean and the resulting impact on ecosystems. Supporting materials include essay and interactive overview of animals that existed in the Basin after the PETM event.

Video length: 8:11 min.

Climate Literacy
About Teaching Climate Literacy

Individual organisms survive within specific ranges of temperature, precipitation, humidity, and sunlight. Organisms exposed to climate conditions outside their normal range must adapt or migrate, or they will perish.
About Teaching Principle 3
Other materials addressing 3a
Scientific observations indicate that global climate has changed in the past, is changing now, and will change in the future. The magnitude and direction of this change is not the same at all locations on Earth.
About Teaching Principle 4
Other materials addressing 4d
Based on evidence from tree rings, other natural records, and scientific observations made around the world, Earth’s average temperature is now warmer than it has been for at least the past 1,300 years. Average temperatures have increased markedly in the past 50 years, especially in the North Polar Region.
About Teaching Principle 4
Other materials addressing 4e
Environmental observations are the foundation for understanding the climate system. From the bottom of the ocean to the surface of the Sun, instruments on weather stations, buoys, satellites, and other platforms collect climate data. To learn about past climates, scientists use natural records, such as tree rings, ice cores, and sedimentary layers. Historical observations, such as native knowledge and personal journals, also document past climate change.

Scientific investigations usually involve the collection of relevant data, the use of logical reasoning, and the application of imagination in devising hypotheses and explanations to make sense of the collected data.
Explore the map of concepts related to this benchmark
The earth's climates have changed in the past, are currently changing, and are expected to change in the future, primarily due to changes in the amount of light reaching places on the earth and the composition of the atmosphere. The burning of fossil fuels in the last century has increased the amount of greenhouse gases in the atmosphere, which has contributed to Earth's warming.
Explore the map of concepts related to this benchmark
The world contains a wide diversity of physical conditions, which creates a wide variety of environments: freshwater, marine, forest, desert, grassland, mountain, and others. In any particular environment, the growth and survival of organisms depend on the physical conditions

Teaching Tips

About the Science

  • This video illustrates how a team of paleontologists and geochemists do field research to determine changes in climate and biota during the PETM.
  • Comments from expert scientist: The video provides a clear and concise view of the way the earth scientists explore past climate change. The topic explored in this resource is relevant. Since the PETM is an analog for modern warming, it captures the viewer's attention and provides a nice example of one approach to projecting future changes on the planet.

About the Pedagogy

  • An essay about the PETM event and impact accompanies the video.
  • In addition there is a link to an interactive activity and a question set that complement the video.
