A More Troubling Picture of Sea Level Rise Is Coming into View

Scientists have uncovered a “blind spot” in the research on rising seas, revealing that tens of millions of people thought safe from coastal flooding are at risk of inundation. Across much of the world, sea levels are higher than previously assumed and land is sinking faster.

By Fred Pearce • April 9, 2026

Excerpt: "The other new study focused on the world’s #RiverDeltas. It has long been known that many #deltas are sinking under the influence of #Groundwater pumping. But as Robert Nicholls, climate adaptation researcher at the University of East Anglia, notes, 'There have been lots of different estimates.' Data were inconsistent and based on crude, delta-wide estimates. 'Now at last we have a consistent data set, with high spatial resolution.'

"That data comes from Leonard Ohenhen, an earth system scientist at the University of California, Irvine, who used satellite-mounted radar to produce 3D maps of subsidence on 40 of the world’s biggest and most populous river deltas. He has found that subsidence afflicts more than half those deltas. Most startlingly, in 18 cases subsidence rates exceed those of #RisingTides — hence, more than doubling the effective yearly rise in local sea levels, and in some cases multiplying it tenfold.

"This again puts tens of millions of people once thought safe from rising tides this century in imminent harm’s way, including those living on the deltas of the #Nile in #Egypt, the #Mekong in #Vietnam, the #Mahanadi in #India, and the #YellowRiver in #China. If the current rate of subsidence persists, these areas will be flooded much sooner than thought.

"Researchers say many deltas and other low-lying coastal areas not included in the two studies are at greater risk than believed and urgently require detailed investigation of both actual sea levels and the rate of land subsidence."

What is clear is that the #KoksilahWatershed is experiencing erratic flow levels throughout the year which is #endangering the health of the entire #ecosystem. , It is also clear that impacts on the #watershed have been accentuated by #ClimateChange. With low elevation, the watershed is losing snow earlier and has more rain in the winter leading to more floods. The current trajectory of the #KoksilahRiver is dire and will impact everyone in the entire watershed.

" #GroundwaterExtraction has the most impact during low flow times of the year, when salmon depend on cooling groundwater inflows for their survival. If wells are drawing from shallow aquifers closely connected to the river, groundwater extraction will immediately reduce in-stream flows. In 2017, 2018 and 2019, in-stream flows in the Koksilah were forecast to become dangerously low, and provincial managers requested voluntary reductions in water use. In each of these years, an order to cease water diversion was under preparation in case voluntary efforts were not enough. In August 2019, a Fish Population Protection Order was issued under the Water Sustainability Act"
