You've already seen the graph on the left, which shows observed and projected changes in fossil fuel carbon emissions. The graph on the right shows projections of direct damage to the U.S economy as a function of global temperature change. This damage includes impacts such as loss of crops due to excessive heat, loss of worker productivity due to extreme temperatures, and impacts to coastal development due to sea level rise. The dots and vertical lines show the result of the model and the uncertainty for that predicted value. The gray shaded area represents the 90% confidence interval for the predicted effects. Evaluate the following statements and determine whether they are supported or not by the data in the graphs. Global Carbon Emissions Direct Damage to U.S. Economy 30 14 25- Higher Scenario (RCP8.5) - 12- 20 10- 15- 8 Fitted values 6- 10 4- 2- Even Lower Scenario (RCP2.6) -Higher Scenario (RCP8.5) 0+5 Lower Scenario (RCP4.5) -2 TT T m 1900 1050 1950 2000 2000 2050 2100 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 Temperature Change (°F) Year Adapted from NCA4 Vol. II, 2018, U.S. Global Change Research Program Drag "Supported" or "Not supported" to the end of each statement. Reset Help Supported A temperature change of 10°F will result in a loss of about 6% of the U.S. gross domestic product. Supported Not supported There is no way for the U.S to eliminate losses to the U.S economy due to climate change. The RCP2.6 scenario will result in the smallest losses to the U.S. economy. Reducing fossil fuel carbon emissions by about 5GtC/yr by the end of the century will limit the rise in temperature to less than 2.5°F. Higher fossil fuel emissions will result in greater damage to the U.S. economy. Fossil Fuel Carbon Emissions 5 0 -5 Observed Lower Scenario (RCP4.5) Even Lower Scenario (RCP2.6)
