Coastal cities such as Washington D.C. could be at risk of severe flooding over the rest of the century, warned a new research. The sea levels in Washington D.C. and Wilmington North Carolina have passed the "Tipping point' already.
Also, other East coast cities may now expect to reach a point where they may have to experience "nuisance-level flooding" for at least 30 days annually by the year 2050.
"Coastal communities are beginning to experience sunny-day nuisance or urban flood, much more so than in decades past. This is due to sea level rise. Unfortunately, once impacts are noticed, they will become commonplace rather quickly," said William Street lead study author and oceanographer.
"We find that in 30 to 40 years, even modest projections of global sea level rise - 1.5 feet by the year 2100 - will increase instances of daily high tide flooding to a point requiring an active, and potentially costly response and be the end of this century, our projections show that there will be near-daily nuisance flooding in most of the locations that we reviewed" he added.
At the annual American Geophysical Union meeting, Street of National Oceanic and Atmospheric Administration (NOAA) explained the reporters that it was an "emergency flooding crisis."
Tide-gauge data and mainstream sea-level-rise projections were used by the new research to show that the frequency of coastal flooding is rising and will continue to rise faster for most parts.
This means, the sea levels will continue to rise as well and for now maximum attention is being given to rise in sea levels.
