Short summary

Globally, lake ecosystems have undergone significant shifts since the 1950s due to human activities. This study presents a unique ~220-year sediment record from a remote Siberian boreal lake, providing a multiproxy perspective on climate warming and anthropogenic air pollution. Analyses of diatom assemblages, diatom silicon isotopes, and carbon and nitrogen sediment proxies reveal complex biogeochemical interactions, highlighting anthropogenic influences even on remote water resources.
