3. Ike’s non-U.S. impacts Cuba suffered $3-$4 billion in damage, and 2.6 million people were forced to evacuate (23% of the population) The Southeast Bahamas had $50-$200 million in damage. Additional heavy damage occurred on the nearby Turks and Caicos Islands. Haiti suffered the most from Ike, with 74 deaths and ruinous flooding.

34. Is the weather getting more extreme?

35. The National Climatic Data Center’s Climate Extremes Index: http://www.ncdc.noaa.gov/oa/climate/research/cei/cei.html 1.Percentage of U.S. with max temperatures much below normal and much above normal. 2.Percentage of U.S. with min temperatures much below normal and much above normal. 3.Percentage of U.S. in severe drought and with severe moisture surplus. 4.Percentage of U.S. with a much greater than normal proportion of precipitation derived from extreme (equivalent to the highest tenth percentile) 1-day precipitation events. 5.Percentage U.S. with a much greater than normal number of days with precipitation and without precipitation.

41. Is the weather getting more extreme? Yes. NOAA (Gleason et al., 2008) concluded that the percentage of the U.S. seeing extreme temperatures and precipitation has generally been increasing since the early 1970s. These increases were most pronounced in summer. No trends were noted in winter. 5 of the 15 most extreme years in the past century occurred since 1997.

42. Will Hurricanes Increase in Frequency and Intensity?

44. Expect a 5% increase in hurricane winds per °C of ocean warming (Emanuel, 2005). Expected increase in SST by 2100: 1-2 °C. Hurricane wind speeds should increase by 5- 10%. Difference in wind speed between a Cat 3 and Cat 4: 15%. Thus, major hurricanes in 2100 should do 1.5 - 3 times more damage than they do now.

45. But Sea Level Rise may be Underestimated

46. 1910-1920: NJ coast was exposed to high water levels from extreme storms less than 200 hours per year. Early 1990's: Coast was exposed to high water from storms of the same magnitude 700 to 1200 hours per year. No increases in storm intensity or frequency that might account for the increasing high water levels. Conclusion: Increase in storm surge exposure of the coast was due to sea-level rise of 1 foot over the 80-year period (Zhang et al.,1997) …Which would lead to increased storm surge damage.
