Vulnerability of Louisiana's coastal wetlands to present-day rates of relative sea-level rise
Coastal Louisiana has lost about 5,000 km2 of wetlands over the past century and concern exists whether remaining wetlands will persist while facing some of the world's highest rates of relative sea-level rise (RSLR). Here we analyse an unprecedented data set derived from 274 rod surface-elevation table-marker horizon stations, to determine present-day surface-elevation change, vertical accreti...
متن کاملThresholds of sea‐level rise rate and sea‐level rise acceleration rate in a vulnerable coastal wetland
Feedbacks among inundation, sediment trapping, and vegetation productivity help maintain coastal wetlands facing sea-level rise (SLR). However, when the SLR rate exceeds a threshold, coastal wetlands can collapse. Understanding the threshold helps address key challenges in ecology-nonlinear response of ecosystems to environmental change, promotes communication between ecologists and resource ma...
متن کاملUncertainties in Measuring Populations Potentially Impacted by Sea Level Rise and Coastal Flooding
A better understanding of the impact of global climate change requires information on the locations and characteristics of populations affected. For instance, with global sea level predicted to rise and coastal flooding set to become more frequent and intense, high-resolution spatial population datasets are increasingly being used to estimate the size of vulnerable coastal populations. Many pre...
متن کاملSpatial Hedonic Models for Measuring the Impact of Sea-Level Rise on Coastal Real Estate
This study uses a unique integration of geospatial and hedonic property data to estimate the impact of sea-level rise on coastal real estate in North Carolina. North Carolina’s coastal plain is one of several large terrestrial systems around the world threatened by rising sealevels. High-resolution topographic LIDAR (Light Detection and Ranging) data are used to provide accurate inundation maps...
متن کاملMultivariate spatio-temporal modelling for assessing Antarctica's present-day contribution to sea-level rise
Antarctica is the world's largest fresh-water reservoir, with the potential to raise sea levels by about 60 m. An ice sheet contributes to sea-level rise (SLR) when its rate of ice discharge and/or surface melting exceeds accumulation through snowfall. Constraining the contribution of the ice sheets to present-day SLR is vital both for coastal development and planning, and climate projections. ...
