Aerosol–cloud interactions are the largest uncertainty in radiative forcing. We combined machine learning and long-term satellite observations to quantify aerosol fingerprints on tropical marine clouds, using degassing volcanic events in Hawaii as natural experiences, and found that cloud cover increased relatively by 50% in humid and stable atmosphere, leading to strong cooling radiative forcing.

Deep CO<sub>2</sub> release and the carbon budget of the central Apennines modulated by geodynamics

The regional geodynamic gradient controls metamorphic carbon release during mountain building and regulates the inorganic carbon budget, according to carbon estimates in two river catchments of Italy’s central Apennines.

Weakening of the Atlantic Meridional Overturning Circulation abyssal limb in the North Atlantic

Nature Geoscience, Published online: 19 April 2024; doi:10.1038/s41561-024-01422-4

Mooring observations and hydrographic data suggest the Atlantic Meridional Overturning Circulation abyssal limb has weakened over the past two decades in the North Atlantic, most likely due to reduced Antarctic Bottom Water formation rates.
