Sea level change doesn't just flood cities, it can also move the ground under them. up and down. Rapid sea-level rise drives increased faulting, and when we look at it relative to glacial sea-level change, one can also see it.

From Fragmentation To Integration - A Review Of Data–Model Integration In Land Subsidence Research
--
https://doi.org/10.1016/j.ancene.2026.100567 <-- shared paper
--
H/T @manonzero current drought conditions, increasing pressure on ecosystems, and ongoing climate adaptation challenges, land subsidence is receiving growing attention worldwide.
For anyone wanting to learn more about land subsidence, or get a refresher, [the authors] provide an overview of the processes involved, the ways it can be measured or estimated, the models used to simulate it, and how observations and models can be combined, [their] new [#openaccess] review paper [link above] may be of interest!
A central message of the paper is that understanding and managing land subsidence requires bringing these different sources of information together…”
--
“HIGHLIGHTS:
• Presents a comprehensive synthesis that unifies all major elements of integral land-subsidence research.
• Defines the methodological steps needed for full integration and positions them within the broader challenges posed by subsidence.
• Brings together and distills the key components of data, modelling, and integration into a coherent framework.
ABSTRACT: Land subsidence, the sinking of the Earth’s surface, is a multi-faceted hazard driven by both natural and anthropogenic factors, and poses significant risk to environments, ecosystems, and society. Despite decades of growing research output, substantial gaps persist between investigations on the diversity of causes, reflected in data and model insufficiency. These gaps hinder the understanding of the issue and impede the effectiveness of mitigation measures. Many studies have urged to include all identified subsidence processes acting in a single area in an integral framework, for which a complex analysis has not systematically been outlined before. Therefore, [they] focus here on bridging the gaps between various technical research disciplines involved. [They] stress the urgency for an integral approach that combines observations with subsurface information of all known subsidence processes in an area, and [they] appeal for utilizing them in physics-guided data integrations. Only then can all subsidence drivers be understood, and effective mitigation measures designed. [They] outline the elements for an integral approach in categorical tables and schematized figures, and [they] discuss the main opportunities and challenges in a stepwise workflow. Leveraging these opportunities naturally leads to more robust, scalable, and policy-relevant solutions and fosters a more sustainable future…”

Beyond The 100-Year Flood - Probabilistic Flood Hazard Assessment For King And Pierce Counties Under Future Climate Scenarios

[part of my old stomping ground as an engineering geologist]
H/T @Kees Nederhoff
“Flood maps are usually built from a single design storm. For King and Pierce Counties in the Pacific Northwest (USA), [the authors] tried the opposite - simulate 82 years of actual coastal and river conditions (plus 18 synthetic years) with SFINCS and let the statistics fall out cell by cell. That took about 5,400 yearly simulations and 194,000 CPU hours on USGS's Hovenweep HPC. Worth it!
The design-event shortcut turns out to hide a real hazard. A deterministic 10-year event underestimated flood depths by up to half a meter compared to the continuous runs.
The bigger surprise [to the authors] was how one-sided the climate signal is. One metre of sea level rise takes King County's expected annual flooded area from 161 --> 787 hectares, almost a factor of five. Changes in storminess over the same horizon barely register. And somewhere between 100 and 150 cm of SLR, land that never floods today starts flooding fast. If you plan adaptation in Puget Sound, that threshold matters more than any single return-period map.
[They] also propose Expected Annual Flooded Area (EAFA) as a probability-weighted alternative to the binary "inside or outside the 100-year zone" label…”

Assessment of Shoreline Change in Southeast Ireland Using Geospatial Techniques
--
https://doi.org/10.3390/su18073280 <-- shared paper
--
"... KEY INSIGHTS:
• Coastlines are highly dynamic — 57% accretion vs 42% erosion
• Strong contrasts between east-facing (Irish Sea) and south-facing (Atlantic) coasts
• Identification of critical erosion hotspots (e.g., Tramore) and accretion zones in embayments
• Coastal change is driven by a combination of wave climate, sediment availability, geology, and human activity

This new paper by @agrinsted (or rather #preprint, it's in #EGUSphere for #TheCryosphere in #OpenReview) is the first one to be submitted under our new #PRECISE project on #IceSheets + #SeaLevel - that officially kicks off next week. It was a very welcome return to the field of #crevasses #Ice + #Fracture that I worked on for my PhD.
Really nice work by Aslak and a clue as to what we're going to be working on the next few years! https://fediscience.org/@agrinsted/111092753792668775 -
