Short summary
Siberia is impacted by recent climate warming and experiences extreme hydroclimate events. We present a 220-year-long sub-decadal stable oxygen isotope record of diatoms from Lake Khamra. Our analysis identifies winter precipitation as the key process impacting the isotope variability. Two possible hydroclimatic anomalies were found to coincide with significant changes in lake internal conditions and increased wildfire activity in the region.
