A new modeling study shows that to accurately interpret data derived from an iconic proxy of past Atlantic overturning strength, we must consider the complex factors governing the proxy systematics.

La corriente de Florida podría estar desacelerándose, pero no por mucho
Una corrección necesaria a un conjunto de datos ampliamente utilizados redujo las estimaciones de los científicos de cómo se ha debilitado la circulación oceánica.
Centennial-Scale Jumps in CO2 Driven by Earth’s Tilt
Antarctic ice records uncovered seven previously unknown jumps in atmospheric carbon dioxide. These events may have been driven by changes in Earth’s tilt.
The Florida Current May Be Slowing Down, but Not by Much
A needed correction to a widely used data set reduced scientists’ estimates of how ocean circulation has weakened.
How Did We Miss 20% of Greenland’s Ice Loss?
The ice loss was hidden in places existing monitoring methods can’t reach, such as hard-to-map fjords. Machine learning helped scientist revise mass loss estimates and uncover patterns in glacial retreat.
Arctic Salinity Pushes the AMOC Swing
A model of the Atlantic Meridional Overturning Circulation (AMOC), pioneered by Henry Stommel over 60 years ago, can exhibit realistic cyclic behavior if the role of Arctic salinity is included.
Nonlinear Effects of Wind on Atlantic Ocean Circulation
Simulations reveal the influence of reduced and enhanced wind stress on the Atlantic Meridional Overturning Circulation.
“Sticky” Ice Sheets May Have Led to More Intense Glacial Cycles
New research attributes a shift to longer, stronger glacial cycles to increased friction between ice sheets and bedrock in the Northern Hemisphere 1 million years ago.
Understanding Abrupt Climate Change in the Late Quaternary
During the late Quaternary period, a series of abrupt climate changes in the tropics and sub-tropics driven by changes in ocean circulation were both dramatic and disruptive.
A 50,000-Year History of Current Flow Yields New Climate Clues
The first high-resolution historical record of Europe’s Glacial Eastern Boundary Current sheds new light on ocean circulation, ice sheet dynamics, and climate change.
