Question

17. The figure below shows the IPCC 5th Assessment temperature anomaly projections for two baseline RCP scenarios for the period from 2081-2100.

Overall, how does the change in average surface temperature in this period differ for the RCP 2.6 pathway from the RCP 8.5 pathway?

RCP 8.5 has smaller (cooler) temperature anomalies

RCP 2.6 has larger (warmer) temperature anomalies

RCP 8.5 has larger (warmer) temperature anomalies

RCP 2.6 has smaller (cooler) temperature anomalies

18. Using the figure in question 17, how does the change in average surface temperature in this period for the RCP 2.6 and RCP 8.5 pathways compare in high northern latitudes to more equatorial latitudes?

a. For both, the change in high northern latitudes is the same as in equatorial latitudes

b. In RCP 2.6 the change in higher northern latitudes is greater than the equatorial regions but for RCP 8.5, the change in equatorial regions is higher than in northern latitudes

c. For both, the change in equatorial latitudes is greater than in high northern latitudes

d. For both, the change in high northern latitudes is greater than at equatorial latitudes

19. Approximately locate Washington D.C. on the RCP 2.6 figure in question 17. What range of change in average surface temperature is expected by 2100 in Washington D.C?
