10% Land mass loss in the future for Miami and New Orleans

Climate change might be a contentious issue with strong opinions on either side of the argument but some things are pretty well known with the fact that some areas of the United States will see a change in their land mass due to rising waters.

In a study done by the University of Arizona over 100 coastal cities are listed as those facing serious risk from rising sea levels. Miami and New Orleans alone could lose up to 10% of their coastal region by 2100.

The University of Arizona research points to global warming trends and effects in the United States that impact coastal areas inhabited by 50,000 or more people and not just those who live on or near the beach. The researchers point out that damage from sea-level rises also infiltrates through creeks, channels, adjacent low-lying areas, and inlets, which means that beach-bums are not the only ones who should be concerned.

“Our work should help people plan with more certainty and to make decisions about what level of sea-level rise, and by implication, what level of global warming, is acceptable to their communities and neighbors,” said co-author Jonathan T. Overpeck.

The researchers also found that global temperature averages will be 8 degrees warmer than they currently are by the year 2100.

“That amount of warming will likely lock us into at least 4 to 6 meters of sea-level rise in subsequent centuries, because parts of the Greenland and Antarctic ice sheets will slowly melt away like a block of ice on the sidewalk in the summertime,” said lead researcher, Jeremy L. Weiss.
