Title: Chapter One - Introduction, Page 5 Title: "Carbon dioxide levels have increase 40% over the past 200 years." NOAA. 270 ppm in 1806. 382 in 2006. Year PPM CO2 Increase 1806 270 - 2006 382 40% (382/200 = 1.41) Title: NOAA Earth System Research Laboratory data provides details. Title: Data is shown in this graph. Actual data is shown in the reference document.

Then draw projection to 2100. Title: By 2100 from the graph it looks like close to 700 ppm. Title: Reference: Atmospheric CO2 Levels and Rates of Change by Thomas J. Pfaff, Ithaca College and Victor J. Donnay, Bryn Mawr College. This is a detailed lesson plan for calculus students. Title: On page five, this formula is shown. y = 0.013 t^2 + 0.518 t + 310.44 Where y = CO2 in PPM t is the year minus 1950. Title: For 2100 what would be the CO2 levels? t = 2100 - 1950 = 150 y = .013 x (150) ^ 2 + .518 (150) + 310.44 y = 292.5 + 77.7 + 310.44 y = 680.64 CO2 ppm Title: This agrees with the graph hand drawn projection. Title: The End Lesson Title: Steven Levy Math, "Livestock's Long Shadow" Chapter 1, Page 5 Lesson Plan for High School Description: This lesson shows how to use a polynomial to make a forecast. Steps: (1) make a graph from the data Make a Graph a) x-axis years, 1950 to 2100 b) y-axis 0 to 800, CO2 PPM c) add these points: Year PPM 1960 317 1970 326 1980 339 1990 354 2000 370 2010 390 (2) sketch the forecast to the year 2100 (3) calculate CO2 level for 2100 using polynomial This lesson shows how math could be used to make forecasts. I will post a video to go with this lesson. Tags: math,polynomial,algebra,climate
