This following graph shows the projected future global average sea surface temperature. On the left hand side of the vertical line are historical (measured) data, whereas data on the right hand side are projected data. Answer the following questions. a) b) Global sea surface temperature change — historical — RCP2.6 — FlCP4.5 — RCPEJJ — FICPB.5 1 980 2000 2020 2040 2060 Year Is this graph showing anomalies? Brie?y explain your answer (Note, this means your answer should tell me that you understand what anomalies are) (2 points) Explain what the different RCP values indicate and why do they predict different temperatures? Relate your explanation to the graph (1.}; which RCP is indicating more or less of a change and why is thatzj3 points) For all RCP's, you see a solid line and a shaded area around the solid line. What is causing this variation? (Note, base your answer on your knowledge on how future climate is predicted) (3 points) What is the relationship between RCP's and emission scenarios? Why are we now using RCP's instead of emission scenarios? (2 points). Why do you think there is also a shaded area round the historical solid line?
