Short summary

We present lipid-based environmental and temperature reconstructions spanning the Holocene from three European varved lakes. At each site archaea are impacted by methane which influence lake water temperature reconstructions, and bacteria appear to respond to oxygen conditions and specific lake and environmental processes. Nonetheless, bacterial temperature reconstructions are comparable to regional climate data, showing the potential of varve archives for high resolution reconstructions.
