Analyze the impact of climate change on sea level rise, study ice cores to understand historical climate patterns, and measure the greenhouse effect on temperature. Use long-term data sets to extrapolate future climates and discuss human activity's impact on the planet.

Activity Exploring the History of Climate Change Students will analyze fabricated ice cores and record their physical and chemical characteristics.
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
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.
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.
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,
Follow procedures in handout and answer Analysis/ Synthesis Questions
