Climate change is posing many challenges to coastal communities. Sea level rise flooding is one of the more obvious symptoms of a warming planet. Other problems include longer, hotter heat waves and droughts. This time of year in South Florida, sargassum seaweed season begins and it can run sporadically right through the fall.
The smelly, scratchy seaweed washes ashore by the ton on hundreds of miles of beaches in South Florida, Mexico and throughout the Caribbean islands. The seaweed drives tourists away and could one day threaten local real estate markets when buyers get fed up.
Scientists say seaweed blooms in the Caribbean and off Brazil are getting worse every year due to global warming heating up the ocean and humans using too much fertilizer on farms and lawns. Runoff containing animal waste from large-scale farms is also a problem.
Coastal communities are employing a number of methods to combat the seaweed. Some plow it into the sand, others truck it away at great expense. Some communities are even exploring ways to harvest and process the seaweed before it ever reaches land.
The sargassum seaweed problem is expected to get worse until humans stop or at least cut back the use of greenhouse gas producing fossil fuels and get water pollution under control. Real estate buyers and owners in coastal communities need to keep an eye on the seaweed problem as it could one day impact the value of their properties.
