Lake El’gygytgyn, Russia Biomarker Data During the Mid-Pleistocene Transition K. R. Lindberg, W. C. Daniels, I. S. Castañeda, and J. Brigham-Grette

Short summary
Earth experiences regular ice ages resulting in shifts between cooler and warmer climates. Around 1 million years ago, the ice age cycles grew longer and stronger. We used bacterial and plant lipids preserved in an Arctic lake to reconstruct temperature and vegetation during this climate transition. We find that Arctic land temperatures did not cool much compared to ocean records from this period, and that vegetation shifts correspond with a long-term drying previously reported in the region.
