The above map shows the dispersion of the 800,000 refugees from Louisiana that fled as a result of the 2005 Hurricane Katrina disaster. This is measured by applicants for federal emergency assistance and is drawn from Chapter 9 of the draft US National Climate Assessment (big pdf). I found the map fascinating for showing how widely the disaster must have drawn on the resources of much of the southeastern US, but also the nation as a whole. I think Hurricane Katrina is a prototype for many 21st century disasters - where the combination of increasingly extreme storms combines with increasingly below sea-level coastal cities. Therefore it's particularly interesting to understand it's impact.
