Short summary
New foraminiferal data from the Bahama region are used to investigate the mechanisms regulating subtropical climate. Our results suggest that the sensitivity of the low-latitude climate increased at times of enhanced sea-surface freshening in the subpolar North Atlantic. This has further implications for future climate development, given the ongoing melting of the Greenland ice sheet.
