  3. Climate Change Activity.doc Part 2 •  Sea Level rise in Hawaii SOEST’s Chip Fletcher • http://www.soest.hawaii.edu/coasts/sealevel/index.html • Watch the movie: • The 1 m contour at high tide - the "Blue Line Project" • Salt water flooding through storm drains in Mapunapuna • Model of Sea-level rise, coastal erosion, and wave overtopping in Waimanalo • Waikiki flooding under 1m of sea level rise

  4. Climate Change Activity.doc Part 3 • Earth Science Highlights: • http://svs.gsfc.nasa.gov/stories/earth_sci_20040422/index.html • Watch the movie: • SEASONS OF CHANGE: EVIDENCE OF ARCTIC WARMING GROWS • THE CASE OF SOOT AND RECEDING ICE

  5. Ice Core Exercise.doc Fig. 1 Age of Ice Core Layers Go to: http://www.pbs.org/wgbh/nova/warnings/stories/icecore.html

  6. Activity Exploring the History of Climate Change Students will analyze fabricated ice cores and record their physical and chemical characteristics.

  7. Compare pH and CO2. CO2 in solution with water becomes carbonic acid, dropping the pH, so measuring relative pH should indicate relative levels of CO2. • Measure particulates • Discussion Questions • Answer Ice Core Research

  8. Greenhouse Effect.doc PurposeMeasure the effect on temperature of a greenhouse gas (carbon dioxide—CO2) on a simulated atmosphere and compare this data against an atmosphere with lower levels of CO2.

  9. Space Atmosphere Land & Ocean Origin Percent (%)incoming Interaction/ Component Percent (%) Interaction/ Component Percent (%) Sun 100 Absorbed by atmospheric H2O, dust, O3 16 Absorbed by ground 51 Absorbed in clouds 3 Backscattered by air 6 Reflected by clouds 20 Reflected by surface 4 Balance 100= +49 +51 Table 1: Global Energy Balance Note: The percent of energy portions vary from author to author, depending upon the literature cited.

  10. Greenhouse gases • Natural • H2O • CO2 • CH4 • O3 • Anthropogenic • CO2 • N2O • CFCs • HFCs • PFCs • SF6 Under clear conditions, void of clouds, H2O vapor is the predominant greenhouse gas (60% to 70%). The second largest source of greenhouse gas is CO2,

  12. Follow procedures in handout and answer Analysis/ Synthesis Questions

  13. Greenhouse gas.doc • Objectives: • Students will: • Discuss the benefits of long-term data sets and studies • Use a long-term data set to plot graphs and examine patterns • Extrapolate what future climates may be like • Use empirical data to discuss how human activity is affecting the planet

  14. Materials: • Access to the Mauna Loa data set or printouts of the spreadsheet • Laptop with Excel • Access to the Mauna Loa data set or printouts of the spreadsheet • BBC News article for students, Ice Cores Unlock Climate Secrets

  15. Follow procedures and answer discussion questions.
