NASA Goddard Space Flight Center Scientific Visualization Studio, USGS (US Geological Survey), NSIDC (National Snow and Ice Data Center)

This interactive visualization adapted from NASA and the U.S. Geological Survey illustrates the concept of albedo, which is the measure of how much solar radiation is reflected from Earth's surface.

Climate Literacy
About Teaching Climate Literacy

When Earth emits the same amount of energy as it absorbs, its energy budget is in balance, and its average temperature remains stable.
About Teaching Principle 1
Other materials addressing 1b
The interconnectedness of Earth’s systems means that a significant change in any one component of the climate system can influence the equilibrium of the entire Earth system. Positive feedback loops can amplify these effects and trigger abrupt changes in the climate system. These complex interactions may result in climate change that is more rapid and on a larger scale than projected by current climate models.

Energy Literacy

The energy of a system or object that results in its temperature is called thermal energy.
Other materials addressing:
1.2 Thermal energy.
Energy is a physical quantity that follows precise natural laws.
Other materials addressing:
Energy is a physical quantity.
Earth's weather and climate is mostly driven by energy from the Sun.
Other materials addressing:
2.3 Earth's climate driven by the Sun.
Physical processes on Earth are the result of energy flow through the Earth system.

Benchmarks for Science Literacy

Light and other electromagnetic waves can warm objects. How much an object's temperature increases depends on how intense the light striking its surface is, how long the light shines on the object, and how much of the light is absorbed.

Teaching Tips

  • This material could be used as homework or as discussion fodder.

About the Science

  • This interactive activity allows students to learn about how materials, such as snow, ice, and water, differ in their ability to reflect and absorb the sun's energy and how melting polar ice creates a positive feedback loop that accelerates global warming.
  • Students investigate how the presence of pollution, such as soot, lowers the albedo of ice and further increases melting. In addition, they observe the decline in Arctic sea ice cover from 1979–2007 and the effect of melting ice on sea levels.
  • Comments from expert scientist: Gives a good clear overview of albedo, and importantly, the ice albedo feedback. Nicely steps from basic concept of albedo, to role of albedo in the climate system.

About the Pedagogy

  • This interactive visualization is an effective tool that could be used in a discussion or as homework.
  • While not a very dynamic presentation, the visualization is effective.

Technical Details/Ease of Use

  • The visualization is downloadable (size = 43 MB).
  • Background essay and discussion questions are provided.
