Safe Mode: On
'Sea Level Rise Due To Global Warming Poses Threat To New York City'

ScienceDaily (Mar. 16, 2009) — Global warming is expected to cause the sea level along the northeastern U.S. coast to rise almost twice as fast as global sea levels during this century, putting New York City at greater risk for damage from hurricanes and winter storm surge, according to a new study led by a Florida State University researcher.


Jianjun Yin, a climate modeler at the Center for Ocean-Atmospheric Prediction Studies (COAPS) at Florida State, said there is a better than 90 percent chance that the sea level rise along this heavily populated coast will exceed the mean global sea level rise by the year 2100. The rising waters in this region -- perhaps by as much as 18 inches or more -- can be attributed to thermal expansion and the slowing of the North Atlantic Ocean circulation because of warmer ocean surface temperatures.

Yin and colleagues Michael Schlesinger of the University of Illinois at Urbana-Champaign and Ronald Stouffer of Geophysical Fluid Dynamics Laboratory at Princeton University are the first to reach that conclusion after analyzing data from 10 state-of-the-art climate models, which have been used for the Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report. Yin's study is published in the journal Nature Geoscience.

"The northeast coast of the United States is among the most vulnerable regions to future changes in sea level and ocean circulation, especially when considering its population density and the potential socioeconomic consequences of such changes," Yin said. "The most populous states and cities of the United States and centers of economy, politics, culture and education are located along that coast."

The researchers found that the rapid sea-level rise occurred in all climate models whether they depicted low, medium or high rates of greenhouse-gas emissions. In a medium greenhouse-gas emission scenario, the New York City coastal area would see an additional rise of about 8.3 inches above the mean sea level rise that is expected around the globe because of human-induced climate change.

Thermal expansion and the melting of land ice, such as the Greenland ice sheet, are expected to cause the global sea-level rise. The researchers projected the global sea-level rise of 10.2 inches based on thermal expansion alone. The contribution from the land ice melting was not assessed in this study due to uncertainty.

Considering that much of the metropolitan region of New York City is less than 16 feet above the mean sea level, with some parts of lower Manhattan only about 5 feet above the mean sea level, a rise of 8.3 inches in addition to the global mean rise would pose a threat to this region, especially if a hurricane or winter storm surge occurs, Yin said.

Potential flooding is just one example of coastal hazards associated with sea-level rise, Yin said, but there are other concerns as well. The submersion of low-lying land, erosion of beaches, conversion of wetlands to open water and increase in the salinity of estuaries all can affect ecosystems and damage existing coastal development.

Although low-lying Florida and Western Europe are often considered the most vulnerable to sea level changes, the northeast U.S. coast is particularly vulnerable because the Atlantic meridional overturning circulation (AMOC) is susceptible to global warming. The AMOC is the giant circulation in the Atlantic with warm and salty seawater flowing northward in the upper ocean and cold seawater flowing southward at depth. Global warming could cause an ocean surface warming and freshening in the high-latitude North Atlantic, preventing the sinking of the surface water, which would slow the AMOC.

  • The whole story is it may happen, not that it is happening. Despite all you read about the polar caps melting, there has been absolutely not change in the water levels near New York. Gorebal Warming is a hoax. There have been no changes in sea levels at all around the world.

    • Facts: "In 1883 the Indonesian volcano Krakatoa exploded releasing an estimated 25 cubic kilometers of greenhouse gases and other particulate pollutant matter into the atmosphere and changed the global climate drastically for years. A deep layer of colder ocean water still exists as result of the Krakatoa eruption.

      Current global greenhouse emissions are pegged at an approximate 27 million metric tons. The comparison: 1 square kilometer =1 billion metric tons; 1 cubic kilometer = 1,000 x 1 More..

    • That's what I heard, it all could be related to the sun activity. It's happened before and will happen again.

      And we are well within the bounds of temperature fluctuations due to solar activity.

      I mean seriously, people cant even do a good job predicting weather trends beyond 5 days, but I am going to be told with certainty about global warming? ROFL

      By all means, I don't think we should trash the planet, but I am not going to be a pushover on the matter... Green tax's anyone?

      And just as anything else, we haven't tracked the levels all across the world in every continent and section of the ocean to see if this is truly a factor.

  • Yep, and just as the "Ozone Layer is Depleting," the tides will lower since everything is cyclical but we haven't measured the long term, 500 year cycle of the tides. This most likely is the effect of the tides being unusually high over a 100 year history if, the tide levels have been tracked for that long, but not over a longer term to see if the levels ever got this high in history. I'm sure they have and people thought the end of the world is nigh back then as well.
