A sediment core from Lake El´gygytgyn (NE Russia) provides a continuous high-resolution record from the Arctic spaning the past 2.8 Ma. The core reveals numerous "super interglacials" during the Quaternary, with maximum summer temperatures and annual precipitation during marine benthic isotope stages (MIS) 11c and 31 ~4-5 °C and ~300 mm higher than those of MIS 1 and 5e. Climate simulations show these extreme warm conditions are difficult to explain with greenhouse gas and astronomical forcing alone, implying the importance of amplifying feedbacks and far field influences. The timing of Arctic warming relative to West Antarctic Ice Sheet retreats implies strong interhemispheric climate connectivity. STUDY NOTES: Multiproxy sediment data from Lake El'gygytgyn, NE Russia for the past 2.800 Ma. Data include core recovery, the age-depth model, sediment facies and mass movement deposits, sediment physical properties, total organic carbon content, paleomagnetic reversals, pollen data, pollen derived temperature and precipitation reconstruction data, and elemental ratio derived from X-ray fluorescence scanning.
