The sea level around Mississippi is 7 inches higher than it was in 1978.1 This increase is mostly due to Mississippi’s sinking land, and it’s causing major issues. Coastal communities, such as the ones along the Mississippi Sound, are protected by barrier islands that are eroding from sea level rise. As this continues, communities could be threatened.2 Ocean water is overflowing more often into the streets during high tides and rain storms. This is not only dangerous for homes, cars, and city infrastructure, but it can also affect drinking water. There are already over 14,000 properties at risk from frequent tidal flooding in Mississippi.3 The state is planning over $1 billion in sea level rise solutions, which include barrier island restoration, dredging, beach renourishment, and hurricane protection.
Sea level rise is speeding up
Although the sea has only risen by 7 inches since 1978, its speed of rise has accelerated over the last ten years and it’s now rising by over 1 inch every 2 years.1 We know this because the sea level is measured every 6 minutes.4 Scientists use different equipment like satellites, floating buoys off the coast, and tidal gauges to accurately measure the local sea level as it accelerates and changes.
