Today’s Highlights
Coastal subsidence dramatically amplifies sea-level rise exposure: a new study finds that the average relative sea-level rise experienced by coastal populations (6 mm/year) is roughly double the climate-driven absolute rate, with 71% of people living in subsiding regions. Meanwhile, Earth system model experiments reveal that AMOC weakening — not warming alone — drives the observed southward migration of the ITCZ, with profound consequences for global precipitation patterns.

Despite its strong influence on relative sea-level (RSL) rise, there is still low confidence in estimates of vertical land motion (VLM) and its contribution to RSL change. To address this problem, we synergize diverse VLM data, which now cover almost 65% of the coastal population, and are key to resolve small scale subsidence, including East, South, and Southeast Asian cities and populated deltaic regions, largely not covered by earlier geodetic measurements. We find that the average modern (1995-2020) global RSL rise experienced by coastal populations (6 mm/year) is about twice the climate-driven absolute sea-level rise. This reflects a strong tendency for higher rates of subsidence in densely populated areas, with 71% of the global coastal population living in subsiding regions. Paired with community efforts to extend consistent observations, these data are essential to ensure reliable estimates of present and future RSL rise to support risk and adaptation assessment.
Migration of the intertropical convergence zone driven by ocean circulation changes

The Intertropical Convergence Zone (ITCZ) is essential to global precipitation patterns and has major socioeconomic and environmental impacts. Yet its future position remains uncertain. Here, using reanalysis data, Earth system model simulations, and targeted sensitivity experiments, we assess risks of the ITCZ crossing any thresholds and find only about one-third of CMIP6 models with a more northern ITCZ mean position-closer to the observed climatological state-simulate a southward ITCZ shift consistent with recent observations. This shift requires a substantial weakening of the Atlantic Meridional Overturning Circulation (AMOC), while the warmer base state alone is insufficient to push it farther north. Furthermore, a collapsed AMOC pushes the ITCZ into the Southern Hemisphere without a warmer base state, and toward the equator when combined with a warmer base state—both cases leading to significant changes in global rainfall patterns. These findings imply that the observed southward ITCZ migration over recent decades is consistent with a weakened AMOC, within the context of coupled atmosphere-ocean interactions.
