A barrier wall proposed by the Army Corps of Engineers as one of several options being evaluated to shield the New York area from rare storms–which may well become less rare and more destructive with global warming–is the subject of a heated debate among planners and environmental experts. Supporters suggest that a barrier be constructed in the outer New York Harbor where it's mostly hidden from view, saying it would go the farthest in protecting people, land and valuable landmarks along the waterfront from a storm surge. Others fear the idea is a short-sighted measure that doesn't address major climate threats–and could even worsen matters by trapping sewage and toxins during flooding from high tides and storm runoff. President Donald Trump, however, remains the sole proponent of the mop-and-bucket approach, as the New York Daily News reports.
