Climate Literacy
About Teaching Climate Literacy

The abundance of greenhouse gases in the atmosphere is controlled by biogeochemical cycles that continually move these components between their ocean, land, life, and atmosphere reservoirs. The abundance of carbon in the atmosphere is reduced through seafloor accumulation of marine sediments and accumulation of plant biomass and is increased through deforestation and the burning of fossil fuels as well as through other processes.
About Teaching Principle 2
Other materials addressing 2d
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.
About Teaching Principle 5
Other materials addressing 5b
Observations, experiments, and theory are used to construct and refine computer models that represent the climate system and make predictions about its future behavior. Results from these models lead to better understanding of the linkages between the atmosphere-ocean system and climate conditions and inspire more observations and experiments. Over time, this iterative process will result in more reliable projections of future climate conditions.

understanding of the climate system is improved through observations, theoretical studies, and modeling
About Teaching Principle O
Other materials addressing Our
The overwhelming consensus of scientific studies on climate indicates that most of the observed increase in global average temperatures since the latter part of the 20th century is very likely due to human activities, primarily from increases in greenhouse gas concentrations resulting from the burning of fossil fuels.

Notes From Our Reviewers The CLEAN collection is hand-picked and rigorously reviewed for scientific accuracy and classroom effectiveness. Read what our review team had to say about this resource below or learn more about how CLEAN reviews teaching materials
Teaching Tips | Science | Pedagogy | Technical Details

Teaching Tips

  • May be useful when discussing the types of data and technology used to understand climate change and oceanographic response to that change.
  • For students to understand images of Earth seen by different satellites, educator may want to pause video and explain what they are seeing.

About the Science

  • Earth-based scientific research is augmented by the NASA Earth Observing satellite system that gathers data about ocean surface temperature, surface winds, sea level, circulation, and even marine life.
  • Information the satellites obtain help us understand the complex interactions driving the world's oceans today - and gain valuable insight into how the impacts of climate change on oceans might affect us on dry land.
  • Emphasis is on the importance of satellites and downplays the importance of surface-based research.

About the Pedagogy

  • Full transcript of narration is available.
  • Video shows satellites looking down at images of Earth but doesn't explain what the images show (infrared images, ocean circulation images, etc.)

Technical Details/Ease of Use

  • Variety of formats and resolution options available to maximize quality.
  • Downloads are slow.
