   New magnetic data from loess and paleosol successions in southern Siberia, track the major climatic variations over the last glacial-interglacial cycle. Profiles of magnetic susceptibility correspond to oxygen isotope stages 1-5. The magnetic-susceptibility data confirm that the wind-vigour magnetoclimatological model is a viable alternative to the classic pedogenic model. These are identified?for the first time in Siberian records as the signature of the abrupt cold pulses responsible for the Heinrich layers in North Atlantic marine sediments. The data form a component of climatic teleconnections across the Northern Hemisphere, allowing correlations to be made among: 1) Siberian magnetic susceptibility stratigraphy, 2) data recorded from other loess-paleosol successions in China, European Russia, Europe, and North America, 3) North Atlantic ice-rafted detritus, and 4) sea-surface temperatures derived from molecular stratigraphy of marine sediments off the northwest coast of Africa.
