A reliable benchmark of the last 640,000 years millennial climate variability
International audience How often have past climates undergone abrupt transitions? While our understanding of millennial variability during the past 130,000 years is well established, with precise dates available, such information on previous climate cycles is limited. To address this question, we id...
