re: #121 Spare O’Lake

Has anyone here actually experienced any change in sea levels - or do we need to be in a satellite to notice it?

Louisiana’s wetlands.

A football-field sized area disappears every 30 minutes. This is due to many factors, but global warming may be one of them:

Since 1930 water has consumed more than 1,900 square miles (4,900 km) of the state’s land. This loss equates to the disappearance of 25 square miles (65 km) of wetlands each year or a football field sized area every 30 minutes.



T

he eastern coastline of Louisiana is much more susceptible to erosion than the western coastline because much of the eastern coastline was created by silt deposits from the Mississippi River. The western coastline is marshy, but the marshes only extend inland by 30 miles (48 km) at the most, then the elevation begins to increase and the marshes fade into solid grounded prairies. Therefore, rising sea levels due to global warming and coastal erosion, are not and will not affect the western coastline as profoundly as it will the eastern half, which may cease to exist.
