  • Coastal Louisiana wetlands face some of the world’s highest rates of relative sea-level rise and loss. Here, the authors show that there is a strong regional component to coastal Louisiana wetland vulnerability to relative sea-level rise as well as contributing to the understanding of subsidence in the region.

  • Extensive damage to coastal Louisiana from Hurricane Katrina in 2005 was largely attributed to high rates of relative sea-level rise caused by coastal subsidence. An examination of the underlying Holocene sediments shows that the compaction of peat-rich deposits contributes significantly to Mississippi Delta subsidence rates of up to 5 mm per year.

  • Over 13 years, coastal Louisiana’s wetlands have been endangered by a sea-level rise rate comparable to what is expected later this century. While the rate may not persist over the next few decades, this natural experiment indicates a 75% drowning of these wetlands by 2070 under current carbon emissions.

  • Without mitigation, relative sea-level rises under current climate change projections will exceed the capacity of coastal habitats such as mangroves and tidal marshes to adjust, leading to instability and profound changes to coastal ecosystems.

  • The world’s largest deltas, home to numerous megacities, are expected to bear the brunt of climate-driven sea-level rise. Now, a study shows that disentangling the human impacts on the Mississippi Delta in the past century can help make these systems more resilient.

  • The beginning of the Holocene interglacial was marked by ice-sheet melting and sea-level rise. A review of sea level and climate records identifies two sea-level jumps associated with the final drainage of glacial Lake Agassiz, and links them to an abrupt cooling event.

  • The 2008 Atlantic hurricane season once again highlighted the challenges awaiting low-lying population centres close to the ocean. In the face of global sea-level rise, unconventional thinking is required to make urban coasts more resilient.

  • Measuring coastal subsidence is essential to evaluating hazards associated with sea-level rise. This Review discusses the processes driving coastal subsidence, space-borne and land-based measurement techniques, as well as models for simulating observed subsidence and predicting future trends.
