MethodsMethods
Normalized 2005 Damages = f(Ly * Iy * Wy * Py,c)
Ly = storm’s loss in year y, in current dollars (i.e., not adjusted for inflation)
Iy= ratio of the 2005 implicit price deflator for GNP to that of year y;
Wy= ratio of the inflation-adjusted 2005 fixed reproducible tangible wealth to that of year y;
Py,c = ratio of the change in the population of the coastal county(ies) most affected by the storm from year y to 2005.

Meaningful data?Meaningful data?
Normalized data contains climate information– ENSO (e.g., Katz 2002)
Consistent with catastrophe model results– Pielke et al. 2000
Includes primarily wind damage, not floodsPossibility of large underestimates pre-1950– NHC collection procedures– Federal hurricane relief– Comprehensiveness of loss estimates
Multiple datasets?

Looking AheadLooking Ahead
What will future damages look like?
Trend: doubling in real terms every 7-12 yearsIf this trend continues by ~2020– 1926 Great Miami = ~$500 billion– 1992 Andrew = ~200 billion– 2005 Katrina = ~320 billion
Damages will continue to riseWe may continue to underestimate loss potentialsSocietal change and climate change
