Remember Katrina? In many regards, it's hard to forget--whether for how it uncovered a side of domestic poverty and racial injustice shocking to most Americans, or for how it blew the door open to tangible discussion of global warming's effect on weather patterns and vulnerable waterfronts. Unfortunately, much of the public shock and awe that followed Katrina has dissipated, and while the city still languishes, struggling to rebuild homes, schools, infrastructure and economy, New Orleans has largely drowned out of the public consciousness.
