Scenario Two: Carbon dioxide emissions decrease • Set the carbon dioxide emissions rate to 9.8 gigatons. • Set the time step size to 10 years. • Select the step forward button once. • Decrease the carbon dioxide emissions by 0.2 and press step forward. • Continue stepping forward once, decreasing the carbon emissions each time, until you reach 2110. • Record the data in the table below. Year Carbon Emissions (gigatons) Temperature (Fahrenheit) 1960 4.2 57.2 1970 5.8 57 1980 6.2 57.4 1990 7.8 57.6 2000 8 58 2010 9.8 58 Decrease carbon dioxide emissions by 0.2 each step forward for the rest of scenario two. 2020 0.2 2030 0.2 2040 0.2 2050 0.2 2060 0.2 2070 0.2 2080 0.2 2090 0.2 2100 0.2 2110 0.2
