What Could Happen to the Ocean’s Carbon If AMOC Collapses
Mass glacier melting may have led this influential ocean current system to collapse at the end of the last ice age. A pair of modeling studies examines how such a collapse could affect dissolved inorganic carbon and carbon isotopes in Earth’s oceans.

How Greenland’s Glacial Troughs Influence Ocean Circulation
Glacial troughs in Antarctica promote mixing of warm and cold water, affecting global climate. A new study explores whether the same is true in troughs along Greenland’s coastline.

Water Density Shifts Can Drive Rapid Changes in AMOC Strength
High-latitude variations in density, which appear to be driven by changes in atmospheric pressure, can propagate to midlatitudes and affect the current’s strength within just a year.

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.
