  abstract = {{T}he {Y}ounger {D}ryas stadial, a cold event spanning 12,800 to 11,500 years ago, during the last deglaciation, is thought to coincide with the last major glacial re-advance in the tropical {A}ndes(1). {T}his interpretation relies mainly on cosmic-ray exposure dating of glacial deposits. {R}ecent studies, however, have established new production rates' for cosmogenic {B}e-10 and {H}e-3, which make it necessary to update all chronologies in this region(1,5-15) and revise our understanding of cryospheric responses to climate variability. {H}ere we present a new {B}e-10 moraine chronology in {C}olombia showing that glaciers in the northern tropical {A}ndes expanded to a larger extent during the {A}ntarctic cold reversal (14,500 to 12,900 years ago) than during the {Y}ounger {D}ryas. {O}n the basis of a homogenized chronology of all {B}e-10 and {H}e-3 moraine ages across the tropical {A}ndes, we show that this behaviour was common to the northern and southern tropical {A}ndes. {T}ransient simulations with a coupled global climate model suggest that the common glacier behaviour was the result of {A}tlantic meridional overturning circulation variability superimposed on a deglacial increase in the atmospheric carbon dioxide concentration. {D}uring the {A}ntarctic cold reversal, glaciers advanced primarily in response to cold sea surface temperatures over much of the {S}outhern {H}emisphere. {D}uring the {Y}ounger {D}ryas, however, northern tropical {A}ndes glaciers retreated owing to abrupt regional warming in response to reduced precipitation and land-surface feedbacks triggered by a weakened {A}tlantic meridional overturning circulation. {C}onversely, glacier retreat during the {Y}ounger {D}ryas in the southern tropical {A}ndes occurred as a result of progressive warming, probably influenced by an increase in atmospheric carbon dioxide. {C}onsidered with evidence from mid-latitude {A}ndean glaciers(16), our results argue for a common glacier response to cold conditions in the {A}ntarctic cold reversal exceeding that of the {Y}ounger {D}ryas.},
