Coastal damage to be more common and extensive?

From The Guardian comes this news:

Marcia McNutt, who last week announced her resignation as director of the US Geological Survey, told a conference that Sandy had left coastal communities dangerously exposed to future storms of any size.

“Superstorm Sandy was a threshold for the north-east and we have already crossed it,” McNutt told the National Council for Science and the Environment conference in Washington. “For the next storm, not even a super storm, even a run-of-the-mill nor’easter, the amount of breaches and the amount of coastal flooding will be widespread.”

McNutt, a professor of marine geophysics, was careful to preface her public remarks by saying she spoke as a scientist and not an Obama Administration official. But the unusually stark warning from a departing Obama official indicates the challenges ahead in protecting American population centres from the extreme storms of a changing climate.

“Before Sandy, someone asked me what my climate change nightmare was. Before Sandy, I said it was that with the extra energy in the atmosphere-ocean system it feeds super storms that intersect mega-cities left rendered defenceless by rising seas,” McNutt said in a brief interview following her public remarks. “That is where we now are.”
