Nova Science Now

This PBS video shows how Klaus Lackner, a geophysicist at Columbia University, is trying to tackle the problem of rising atmospheric CO2 levels by using an idea inspired by his daughter's 8th-grade science fair project.

Video length: 12:06 min.

Climate Literacy
About Teaching Climate Literacy

Humans may be able to mitigate climate change or lessen its severity by reducing greenhouse gas concentrations through processes that move carbon out of the atmosphere or reduce greenhouse gas emissions.
About Teaching the Guiding Principle
Other materials addressing GPd
A combination of strategies is needed to reduce greenhouse gas emissions. The most immediate strategy is conservation of oil, gas, and coal, which we rely on as fuels for most of our transportation, heating, cooling, agriculture, and electricity. Short-term strategies involve switching from carbon-intensive to renewable energy sources, which also requires building new infrastructure for alternative energy sources. Long-term strategies involve innovative research and a fundamental change in the way humans use energy.
About Teaching the Guiding Principle
Other materials addressing GPe
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
mate is regulated by complex interactions among components of the Earth system
About Teaching Principle C
Other materials addressing Cli
Natural processes that remove carbon dioxide from the atmosphere operate slowly when compared to the processes that are now adding it to the atmosphere. Thus, carbon dioxide introduced into the atmosphere today may remain there for a century or more. Other greenhouse gases, including some created by humans, may remain in the atmosphere for thousands of years.

Teaching Tips | Science | Pedagogy | Technical Details

Teaching Tips

  • Use to teach both about climate science and scientific method/research process.
  • Educator should be aware that resource could be construed as advertising for this particular technology.

About the Science

  • Discusses problem of increased CO2 emissions, greenhouse effect, and carbon sequestration.
  • Scientist's research project tries to mimic what a tree can do in terms of absorbing CO2, and releasing O2.
  • Comments from expert scientist: This is an interesting idea, but video should take into account the total estimated cost of removing CO2 from the atmosphere including materials, transportation, installation and not just the electricity used.

About the Pedagogy

  • Interesting and engaging video about current research and development of innovative ideas related to trapping carbon.
  • Video models the use of scientific method for solving complex problems.
  • A 15-second commercial precedes video.

Technical Details/Ease of Use

  • Has closed-captioned text that can be turned on/off
