Short summary

Regional variability and changes in ocean dynamics during 1900–2015 were obtained in the western North Atlantic Ocean from a global sea level reconstruction. An unprecedented long period of weakening in the Gulf Stream (GS) flow since the late 1990s was found. The variability and slowdown of the GS were related to the Atlantic Meridional Overturning Circulation. The reconstruction captured observed variability in the coastal sea level and GS flow on timescales of ∼5–50 years very well.
