Teaching Tips

  • Use this video with Richard Alley in conjunction to any of the other CLEAN selected resources about the Earth's energy balance, carbon dioxide and the greenhouse effect.

About the Science

  • This short video explains the simple physics of the greenhouse effect and how more carbon dioxide in the atmosphere causes Earth to warm.
  • It shows graphs of atmospheric carbon dioxide and global mean temperature over hundreds of thousands of years.
  • The video does not cite the source of the graphs nor does it offer an explanation of how these graphs were developed or how these data are causally related. That said, this data is consistent with the scientific consensus and similar graphs are scientifically accepted.
  • Comments from expert scientist: Strengths include the clear verbal message and use of animated graphics.

About the Pedagogy

  • The presenter, Richard Alley, is a well-known climate scientist and an excellent communicator. The video is engaging and the graphics are colorful and fun.
  • There is background material on the main website - http://www.ei.lehigh.edu/eli/cc/index.html.

Technical Details/Ease of Use

  • The video resolution is sufficient for projection in a classroom.

Next Generation Science Standards See how this Video supports:

Middle School

Disciplinary Core Ideas: 1

MS-ESS3.D1:Human activities, such as the release of greenhouse gases from burning fossil fuels, are major factors in the current rise in Earth’s mean surface temperature (global warming). Reducing the level of climate change and reducing human vulnerability to whatever climate changes do occur depend on the understanding of climate science, engineering capabilities, and other kinds of knowledge, such as understanding of human behavior and on applying that knowledge wisely in decisions and activities.

High School

Disciplinary Core Ideas: 1

HS-ESS2.D3:Changes in the atmosphere due to human activity have increased carbon dioxide concentrations and thus affect climate.
