Frank Capra, Bell Telephone Science Hour

Bell Telephone Science Hour produced this video in 1958, explaining how the production of CO2 from factories and automobiles is causing the atmosphere to warm, melting the polar ice caps, and causing the sea level to rise.

Video length: 1:55 min.

Climate Literacy
About Teaching Climate Literacy

Emissions from the widespread burning of fossil fuels since the start of the Industrial Revolution have increased the concentration of greenhouse gases in the atmosphere. Because these gases can remain in the atmosphere for hundreds of years before being removed by natural processes, their warming influence is projected to persist into the next century.
About Teaching Principle 6
Other materials addressing 6b
Human activities have affected the land, oceans, and atmosphere, and these changes have altered global climate patterns. Burning fossil fuels, releasing chemicals into the atmosphere, reducing the amount of forest cover, and rapid expansion of farming, development, and industrial activities are releasing carbon dioxide into the atmosphere and changing the balance of the climate system.

man activities are impacting the climate system
About Teaching Principle H
Other materials addressing Hum
Melting of ice sheets and glaciers, combined with the thermal expansion of seawater as the oceans warm, is causing sea level to rise. Seawater is beginning to move onto low-lying land and to contaminate coastal fresh water sources and beginning to submerge coastal facilities and barrier islands. Sea-level rise increases the risk of damage to homes and buildings from storm surges such as those that accompany hurricanes.

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.

Human activities, such as reducing the amount of forest cover, increasing the amount and variety of chemicals released into the atmosphere, and intensive farming, have changed the earth's land, oceans, and atmosphere. Some of these changes have decreased the capacity of the environment to support some life forms.
Explore the map of concepts related to this benchmark
By burning fuels, people are releasing large amounts of carbon dioxide into the atmosphere and transforming chemical energy into thermal energy which spreads throughout the environment.

Teaching Tips | Science | Pedagogy | Technical Details

Teaching Tips

  • Teachers should embed this video in a presentation to create conversation about the history of atmospheric science and climate change.
  • Today we have data regarding the amount of CO2 in the atmosphere, changes in air temperature, sea level rise, and ice cap melting that confirms the comments made by the scientist in the 1958 video.

About the Science

  • This video, produced during the International Geophysical Year in 1958, focuses on how increasing atmospheric CO2 through industrial processes will absorb more heat, raise atmospheric temperatures, and likely cause melting of the polar ice caps, resulting in sea level rise.
  • Passed initial science review - expert science review pending.

About the Pedagogy

  • The video demonstrates that the scientific community has understood for decades that increases in gases that trap heat can impact global temperatures and lead to "catastrophic changes in our environment." This video explains that CO2 from automobiles and factories could cause global temperatures to rise, melting ice caps and causing a rise in sea level.

Technical Details/Ease of Use

  • The video is of very good quality with a classic look and sound.
