Teaching Tips | Science | Pedagogy |
- If video is implemented in middle or high school classrooms, pausing periodically to review and discuss might help students absorb the breadth of the information.
- Prepare handouts with the different graphs and let students take notes directly on them.
- Provide students the opportunity to ask questions and research how the data was collected, limitations of the data sets, and assumptions made in the data analysis.
- The following resources may give students the opportunity to easily analyze the data presented in the video: Mauna Loa CO2 measurements: http://www.esrl.noaa.gov/gmd/ccgg/trends/#mlo_data Concentrations of CO2 from year 0 to 2005: http://www.globalchange.gov/HighResImages/1-Global-pg-14.jpg; Paper written by Revelle and Seuss: http://onlinelibrary.wiley.com/doi/10.1111/j.2153-3490.1957.tb01849.x/pdf; Paper written by Bolin and Eriksson: http://nsdl.org/sites/classic_articles/Article8.htm GlobalView CO2 Map: http://www.esrl.noaa.gov/gmd/ccgg/globalview/co2/co2_documentation.html; Recent Monthly CO2: http://www.esrl.noaa.gov/gmd/ccgg/trends/mlo.html; Ice Age Cycles (800,000 years): http://nas-sites.org/americasclimatechoices/files/2012/10/Figure-14.png; Atmospheric Methane, Nitrous Oxide, and Carbon Dioxide Concentrations and Radiative Forcing: http://www.ipcc.ch/publications_and_data/ar4/wg1/en/spmsspm-human-and.html; Global Methane vs. Time: http://www.noaanews.noaa.gov/stories2006/images/methane-global-average-05-2006b.jpg; Global CFC concentrations vs. Time: http://www.sciencedirect.com/science/article/pii/S0269749199000883; AIRS Mid-Tropospheric Carbon Dioxide animation: http://airs.jpl.nasa.gov/news_archive/2010-03-30-CO2-Movie/; Nations' CO2 production since the Industrial Revolution: http://barryonenergy.wordpress.com/2012/04/17/ghg-on-the-rise/
About the Science
- This video explains why we know that humans have caused greenhouse gas concentrations to increase.
- Evidence includes measuring atmospheric greenhouse gas inputs and uptakes through direct measurements, satellite measurements, and analysis of carbon isotopes.
- Comments from expert scientist: The material goes through the main greenhouse gases and provides a discussion and graphs to indicate that they are increasing in a way that is unprecedented in the records up to now. It highlights the molecules –carbon dioxide, methane, and nitrous oxide and CFCs and states information about their production and states how they are both natural and produced by humans.
About the Pedagogy
- No additional supporting materials.
- Video is methodical in its historical approach to the story, providing records of the scientists contributing to the study of CO2 in our atmosphere and greenhouse gas concentrations. Science-heavy video covering a lot of data.
- Because of the wide variety of data covered in this video, students may need additional support to understand the graphs. URLs for the graphics are listed in the "Related URL" field below.
- Graphs and other visuals may need more time for real understanding.
