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…”

Romero et al present an ice-free and paleo sea level chronology for James Ross Island in the northeastern Antarctic Peninsula area. They found that the advance of the local ice cap happened sometime after 40,000 years ago, and this implies a period of retreated ice in MIS 3.

Scientists confirmed the new high, warning of consequences for #weather patterns, #sealevel rise, and #marine #ecosystems. Experts project 2026 could become the hottest year on record, with 2027 likely hotter still.

While there is agreement that sea levels are rising (not just subsidence, the only way some parts of the world are allowed to talk about it). But we're still working on the "how much" and what is the scale of the different contributors.

How is this for a feedback loop?
Ice sheets build up during a glaciation lowering global sea level → reduced water load leads to increased mid ocean ridge volcanism after a 10-20 kyr lag → volcanism releases iron in the ocean → iron causes plankton blooms → atmospheric CO₂ goes down → ice sheets build up
