Summary: The Arctic is warming much faster than the rest of the planet. This warming can be amplified or attenuated by natural climate variability. However, the sparse meteorological and instrumental data in the Arctic, when available, do not extend beyond the last 50 years. This reality prevents an adequate understanding of the climate system in this highly vulnerable region. To overcome this lack, we use annually laminated sediments (varves) at the bottom of Arctic lakes. This allows us to go back in time, typically several millennia before present, with annual temporal resolution.
