Climate Change and Low-Lying Coastal Mississippi River Delta, USA – February 17th, 201329.9N 90W
Here, sediments can be seen spilling forth from the Mississippi River in Louisiana, USA. The low lying, coastal Mississippi River Delta region is particularly vulnerable to the climate change threats of sea level rise, increased flood risk and more intense hurricanes. The area is additionally plagued by human-induced environmental degradation that has occurred over the past 200-300 years. The region has lost 1,900 square miles of land since the 1930s and is losing the wetland areas that are crucial to the region’s ecosystem function, economy and character.
Global climate change has induced an increase in global mean sea level with a 3.1 mm/year average rate of increase since 1991. Climate projections indicate a widespread increase of more intense precipitation events, with an associated increased risk of flooding. Similarly, climate scientists also predict an increase in hurricane wind speed and total volume (click here for more information).
