Short summary
Isotopes of atmospheric O2 undergo millennial-scale variations during the last glacial period, and systematically increase during Heinrich stadials. Such variations are mostly due to vegetation and water cycle processes. Our modeling approach reproduces the main observed features of Heinrich stadials in terms of climate, vegetation and rainfall. It highlights the strong role of hydrology on O2 isotopes, which can be seen as a global integrator of precipitation changes over vegetated areas.
