Deep learning based reconstructions of the Atlantic meridional overturning circulation confirm twenty-first century decline

Environmental Research Letters
Gaining knowledge of the past and present variations of the Atlantic meridional overturning circulation (AMOC) is crucial for the development of accurate future climate projections.

Pantropical Indo-Atlantic temperature gradient modulates multi-decadal AMOC variability in models and observations

npj Climate and Atmospheric Science, 2023
Interconnections between ocean basins are recognized as an important driver of climate variability. Recent modeling evidence suggests that the North Atlantic climate can respond to persistent warming of the tropical Indian Ocean sea surface temperature ...

The South Atlantic Meridional Overturning Circulation at 34.5°S in 2017 and 2022

Journal of Geophysical Research: Oceans, Volume 131, Issue 10, October 2026.
Abstract The Atlantic Meridional Overturning Circulation (AMOC) at 34.5°S is investigated using hydrographic data from two research cruises conducted in 2017 and 2022. Data from the South AMOC Basin‐wide Array (SAMBA) are used to close the 2022 section.

Simulated Ocean Oxygen Under Miocene Boundary Conditions

Paleoceanography and Paleoclimatology, Volume 41, Issue 10, October 2026.
Abstract The Miocene Climatic Optimum (MCO; 16.9–14.7 Ma) was a warm interval with atmospheric CO2 ${\text{CO}}_{2}$ comparable to end‐of‐21st‐century projections under intermediate emission scenarios. Proxy records indicate the Oxygen Minimum Zone (OMZ) in the Eastern Tropical Pacific (ETP) was small or non‐existent during the MCO, expanding only when

Deciphering the Link Between Modeling Errors and the North Atlantic Surface Warming Pattern Projected by CMIP5 and CMIP6 Models

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract The North Atlantic Subpolar Gyre (NASG) has warmed much less than the global ocean over recent decades, thereby suggesting a human‐caused slowdown of the Atlantic Meridional Overturning Circulation (AMOC). This North Atlantic “warming hole” is also found in climate projections, yet with a model‐dependent timing, location and intensity. Here we

Diagnosing the Atlantic Meridional Overturning Circulation in density space is critical in warmer climates [PDF]

Ocean Science
The Atlantic Meridional Overturning Circulation (AMOC) plays a crucial role in shaping the global climate system by redistributing heat and influencing large-scale climate patterns.

New Constraints on the Onset of Antarctic Glaciation From Combined Radiogenic Hafnium and Neodymium Isotopes

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract The drawdown of atmospheric CO2 likely triggered Antarctic glaciation during the Eocene‐Oligocene Transition (34 Ma). Accurately constraining this shift from “greenhouse” to an “icehouse” climate is essential for understanding global carbon cycle dynamics.

AMOC-emulator M-AMOC1.0 for uncertainty assessment of future projections

, 2016
State-of-the-science global climate models show that global warming is likely to weaken the Atlantic Meridional Overturning Circulation (AMOC). While such models are arguably the best tools to perform AMOC projections, they do not allow a comprehensive ...
