A speleothem record of Holocene climate variability from southwestern Mexico
Abstract A paleoclimate reconstruction for the Holocene based upon variations of δ 18 O in a U–Th dated stalagmite from southwestern Mexico is presented. Our results indicate that the arrival of moisture to the area has been strongly linked to the input of glacial meltwaters into the North Atlantic...
