2011 represents the highest damage cost-to-date in the U.S. for any year since 1980 when we began tracking Billion-dollar disasters. Economic damage costs to date in the US approach $32 Billion. The damage cost-to-date in the U.S. from natural disasters is typically less than $6 Billion, from the usual combination of winter storms, crops losses due to cold weather, springtime flooding and severe weather outbreaks.”
