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

Increased hydrothermal iron inputs from mid-ocean ridges, triggered by ice-age sea-level falls, supported higher surface primary productivity during the last two glacial terminations, according to proxy records of nutrient consumption in the eastern equatorial Pacific Ocean.

Two sister cities. A rising sea level. A shared thought experiment. 🌊
// How to bridge San Francisco and Kiel – A Sea Level Project
What if Kiel and San Francisco shared a clock – calibrated not to seconds, but to the rising sea? Jonathon Keats, Stephan Juricke, Tim Logan & Axel Schulz think it through at #Waterkant26.

Sea level rise is speeding up and scientists now know exactly why https://www.sciencedaily.com/releases/2026/05/260522023116.htm

The world’s oceans are rising at an accelerating pace, and scientists now say they can fully explain what’s driving it. Warming seawater is the biggest factor, while melting glaciers and polar ice sheets are increasingly pouring more water into the oceans each year. Researchers also solved a puzzling mismatch in sea level measurements that had lingered for years.
