The East Coast of the U.S. is sinking!
February, 2024
A new study published in nature combine the increasing threat of sea level rise with new satellite-based methods capturing land subsidence. A few millimeters of sinking plus a few millimeters of sea level rise per year can seem gradual, but the effects can be extreme. Especially when you include the overland flow of storm waters and the groundwater flow of higher water tables. Multiple articles have been written expressing their concern for SWISLR. The Seattle Times and New York Times discusses the impacts land management actions throughout history have had on the subsidence rates we are seeing today. An article published in CNN, also promoting this new study, reiterates the importance of studying the land subsidence and sea level rise together. When these two processes are thought of in tandem, predictions of at risk populations and buildings increases significantly.

As Saltwater Encroaches on Farms, Solutions Emerge From the Marshes
By Lisa Held, January 15th, 2024
Rising seas and saltwater intrusion threaten crop land globally. A farmer in New Jersey has decided to work with the encroaching marsh grasses and create plots of land where various tidal grasses will be grown to not only help erosion and flood control for the other fields, but also can be harvested as hay and as plugs for others to plan their own wetland buffers. Predictions estimate that farmers in the Mid-Atlantic are likely hotspots of saltwater intrusion risk. The farmers in these areas mostly grow corn and soy, but these plants can not survive the harsh salt mixture that is intruding into the fields. Farmers will have to adapt! Some farmers build dikes and gates that stop the water from coming onto their fields while others try to plant more salt tolerant crops that are also able to deal with the excess water from sea level rise, like tidal grasses. Farmers and researchers are working together to come up with solutions for these plots of land threatened by SWISLR.

A Flood-prone historic site decides to live with rising water rather than fight it
by Brady Dennis, January 1st, 2024
Areas like Wilmington North Carolina are constantly inundated with coastal waters, stressing the social and eco-systems along the coastlines. However, museum leaders at The Battleship North Carolina museum has decided to do something about the inundation they are facing. Leaders and pursuers of the museum have noticed the dramatic increase in tidal flooding since its opening in 1961. "In 2022, even though the museum had nearly a quarter-million visitors and its most successful financial year ever, the site experienced nearly 200 days of flooding." In response, the site's leaders decided to live with the water instead of trying to hold back the rising waters. The project plans to replace concrete barriers and rocky armoring with living shorelines and native vegetation, restore part of the parking lot to a tidal creek and wetland, and use green infrastructure for the remaining parking areas. Construction is expected to begin soon and wrap up ahead of the 2024 hurricane season, setting an example of what living with water could mean for the rest of North Carolina.

Ghost forests threaten New Jersey's Water ecosystem
by Ginger Zee, Lindsey Griswold, Daniel Manzo, and Ivan Pereira, Nov. 29th, 2023
Saltwater intrusion is killing the Atlantic white cedar trees throughout southern New Jersey. Through a combination of Superstorm Sandy, logging in the area, and the regional sea level rise of 4 inches in the last 30 years the soils lost their freshwater and could no longer support the white cedar trees, resulting in acres of 'ghost forests' throughout the area. These wetlands are important ecosystems providing many ecosystem services. Efforts are underway to replant trees and facilitate new growth of this vitally important cedar forest.

New Orleans's Saltwater Intrusion Scare Is a Reminder of a Nationally Looming Threat
By Marlowe Starling, Emily Driehaus, Aarohi Sheth, Oct. 31st, 2023
Although New Orleans adverted the saltwater intrusion threat to drinking water, many low-lying coastal towns further downstream of New Orleans and throughout the country still face the burden of salty drinking water. Combined drought, sea level rise, and decreased groundwater have increased the threat of saltwater intrusion to low-lying areas. These threats aren't new, but the federal emergency for New Orleans's saltwater intrusion threat allows for more attention on the topic of SWISLR. This article explains the scope of the problem and the risks associated with SWISLR for low-lying coastal communities.

Saltwater in the Mississippi Threatens Water Supply in New Orleans
by Colbi Edmonds, Sept. 23rd, 2023
New Orleans most recent threat is saltwater intrusion in their drinking water systems due to the drought conditions over the summer. Reduced water levels in the Mississippi river means that the salt wedge from the Gulf of Mexico is able to travel further north, potentially reaching water treatment plants near New Orleans in October. Back in July the Army Corps of Engineers built an underwater sill in the Mississippi aimed at stopping the slat wedge from moving north. Work will soon begin to make the sill higher to counteract the increased saltwater threat, but this is still just a band-aid for the problem and the progression of saltwater will continue if there isn't significant rainfall soon. Clean drinking water is being shipped to the threatened areas. The threat of SWISLR to drinking water is just one more issue many coastal communities are currently facing.

Here’s a Look at the Water Crises That Might Be Coming to You Soon
By Somini Sengupta, June 25th 2023
This story is a look at Bangladesh - how climate change is shifting the landscape and water availability, and how communities in Bangladesh are coping with these threats. The low lying delta of Bangladesh is one of many places that is at the forefront of climate issues, facing threats that the rest of the world may face in the future.
Flooding is affecting coastal farm land and rice production. One story described within this article talks about flash floods affecting the timing of harvest and decreasing the yields of produce. To counteract flooding, the use of floating gardens is spreading across Bangladesh, where farmers are able to grow their crops on top of the water. However, this does not solve saltwater intrusion - and the increasing salinity is changing more than just the farms. The mangrove forest, that provides flood and storm protection, are dying and new mangrove species are taking over. The impact this shifting ecosystem will have on local communities is not yet known.
A more direct salinity impact on local communities is the drinking water supply. Many efforts are being made to counteract the increasing salinity to farm fields and drinking water like growing vegetables in pots or collecting rain water for a drinking supply. These reactions to climate hazards are not a long-term solution, and the United Nations estimates that at leas $160 billion a year is needed for adaptation efforts in developing nations globally. Although these are stories of successful adaptation to current changes, without support or global emission reduction, "Bangladesh can do little to stay above the surface... Whatever we do is not going to be enough" (Mr. Chowdhury, the lawmaker).

New studies show 'unprecedented' sea-level rise along the North Carolina coast
By Gareth McGrath USA Today Network, April 25th 2023
Sea levels are rising faster than what most scientists had expected - the World Meteorological Organization found that "global sea levels are rising at more than double the pace they did during the first decade of measurements from 1993 to 2002, and hit a new record high last year." Recent work at Tulane University and the Virginia Institute of Marine Science at William & Mary have shown the increase in SLR in these past few decades.

Retreat in Rodanthe
Story by Brady Dennis, March 13th 2023
The sea has taken yet another home along the coast of North Carolina. The outer banks community is home to some of the most rapid rates of erosion and regional SLR. More and more houses are at risk of collapse, and as their risk grows, fewer options are available to homeowners for these risky properties. Instead of solutions, homeowners are faced with just trying to by time until their property is eventually taken by the sea as well. There are disagreements on what can be done and who is responsible, some wanting to protect what they have with government support (e.g. beach nourishments) while others want to move away - which would be at their own cost. Both options come with repercussions that make the choice impossible.

Worried about Sea Level Rise? Look for the Lichens.
By Ian Rose February 28th, 2023
Knowing which coastal areas are at risk of SWISLR is a massive task that is at the top of many people's list. Lichen can potentially help identify areas that are at risk of increasing SWISLR. Roger Rosentreter and Ann DeBolt - botanists at Boise State University - have studied lichen communities at two state parks. The state park closer on a barrier island is subject to SWISLR, while the other is 500 meters inland. Rosentreter and DeBolt have started building a list of species that can withstand SWISLR and can be used as indicators for the presence of SWISLR.

Rising Sea Levels Are Threatening Affordable Housing. What Can Local Governments Do?
By Nyla Holland January 18th, 2023
Sea Level Rise threatens coastal communities and ecosystems. Communities are already at risk to floods and storm inundation from the current sea level, with racial and economic legacies exacerbating the damages. Nyla Holland introduces 5 things that local governments can do to combat sea levels. 1) Determine the flood risk, 2) Develop resiliency with elevation, 3) Create gray and green infrastructure, 4) Implement zoning, buyout, and relocation programs, and 5) Engage community members.

Rising sea levels could swamp the US coastline by 2050, NASA predicts
By Joe Phelan, November 30th 2022
A new study analyzing three decades of satellite data finds that sea level rise is accelerating. By 2050 sea levels could rise a foot above current waterlines. With new satellites gathering data our understanding of sea level rise is increasing. Some hope that findings like these will encourage decision-makers to focus on address the current climate crisis.

Saltwater is moving up the Mississippi River. Here's what's being done to stop it
by Debbie Elliott, October 27th 2022
Due to droughts in Louisiana, the salt wedge is moving further up the Mississippi river. The salt water is impacting municipal water and commercial water use. The US corps of engineers is planning to build an "underwater levee," aka. a berm of sand that will stop the saltwater from moving further upstream.

'Ghost forests' are creeping across NC's coast at an alarming rate. Researchers are trying to stop them.
by Jack Igelman, August 12th 2022
Ghost forests are spreading with climate change. The coastal area of North Carolina known as Down East is vulnerable to many climatic hazards. Duke doctoral candidate, Patrick Gray, has found that the evolution of ghost forest is "a slow-motion haunting, as the shifting ecological change occurs over months, years or decades." However, Down East residents don't see these shifts as a threat. Instead, "what people see as an existential threat are the problems of fish politics, development, getting priced our of their communities." This Carolina public press article goes on to state that the protection of vulnerable coasts needs to include the people who live and develop the landscape.

Sand dunes experience significant erosion due to sea-level rise and extreme storms
By Alan Williams, July 20th 2022
As sea levels rise sand dunes are moving landward. Due to coastal infrastructure, the migration of dunes is not possible in urban areas which may cause a loss of dune habitat. Researchers are surveying and modeling dune migration. A recent article found that Dunes have been retreating at an average rate of 0.5-1 m per year.

As sea levels rise, coastal wetlands are expected to change dramatically
By Sophia Friesen, July 5th 2022
Researchers at the Wetland and Aquatic research center in Louisiana find that rising sea levels will cause widespread loss of coastal wetlands, especially in North Carolina. As sea levels rise, coastal wetlands will potentially move inland and take over freshwater wetlands as salt intrudes inland, while the original saltwater wetlands drown due to the higher sea levels.
