4. Recall the researchers' two predictions: droughts will last longer rainy periods will be wetter Are these predictions supported by the data from Figure 3? For each prediction, give a specific example from Figure 3 that demonstrates how the prediction is supported or not supported, citing the years and/or the rainfall amount as appropriate. RESPONSE: Yes, these predictions are supported by the data presented in figure 3. The intensity of wet periods has increased along with the recurring drought period. E.g., the intensity of the wetter period has increased phenomenally in the 20th century. 7 out of 10 wettest years have occurred in the 20th century and the 20th century was also the century worst affected by droughts evident in the higher proportion of line below the mean rainfall line. Thus, both observations stand true. 5. In the scientific method, when a prediction turns out to be true, the hypothesis that generated the prediction is supported. When a prediction is false, the hypothesis is not supported. Do you think that the hypothesis that weather cycles in northwestern Australia are more extreme now than in the past is supported? Use your response to Question 4 to justify your answer. 700 Instrumental Rainfall ( mm) Reconstructed Rainfall 600 500 400 Rainfall (mm) 300 200 100 Series "Reconstructed Rainfall" Point "1849" Value: 195,09 0 1800 1805 1810 1815 1820 1825 1830 1835 1840 1845 1850 1855 th th tho 9988 ARBRE 2010 Year
