Sandy gave us just a taste of what's coming, and points to the tasks ahead, experts write:
As scientists who study sea level change and storm surge, we fear that Hurricane Sandy gave only a modest preview of the dangers to come, as we continue to power our global economy by burning fuels that pollute the air with heat-trapping gases.
This past summer, a disconcerting new scientific study by the climate scientist Michiel Schaeffer and colleagues — published in the journal Nature Climate Change — suggested that no matter how quickly we cut this pollution, we are unlikely to keep the seas from climbing less than five feet.More than six million Americans live on land less than five feet above the local high tide. (Searchable maps and analyses are available at SurgingSeas.org for every low-lying coastal community in the contiguous United States.)...There are two basic ways to protect ourselves from sea level rise: reduce it by cutting pollution, or prepare for it by defense and retreat. To do the job, we must do both. We have lost our chance for complete prevention; and preparation alone, without slowing emissions, would — sooner or later — turn our coastal cities into so many Atlantises.
