High-resolution Greenland Ice Core data show abrupt climate change happens in few years
Udgivelsesdato: 1 August The last two abrupt warmings at the onset of our present warm interglacial period, interrupted by the Younger Dryas cooling event, were investigated at high temporal resolution from the North Greenland Ice Core Project ice core. The deuterium excess, a proxy of Greenland pre...
