A new study finds that rising seas from climate change will bring in the second half of this century frequent flooding at elevations now only inundated once in every 100 years… Sea level in North Carolina is forecast to rise by between 12 and 20 inches by the middle of the century and by as much as 4.2 feet by the year 2100 unless there is a substantial reduction in greenhouse gas emissions, according to a new study published in the journal Climate Change… “Scenarios of future rise are dependent upon understanding the response of sea level to climate changes. Accurate estimates of past sea-level variability provide a context for such projections,” said Rutgers oceanographer Benjamin Horton, another of study’s authors.
