Behavioral Economics and Climate Change

Cass Sunstein suggests that we aren't scared enough of climate change.  He should consider distinguishing public action (i.e carbon pricing) versus private action (i.e individuals and companies moving away from flood plains).   This recent WSJ article suggests that private climate adaptation is taking place just as I predicted it would in Climatopolis!   An empirical issue arises, can the wealthy who are building big houses on stilts in these risky  (but beautiful) coastal areas withstand a punch in their new housing?    I believe the answer is yes.
