Short summary
We use cave rocks to reconstruct northern Siberian climate in 8.68 ± 0.09 Ma. We show that when the global average temperature was about 4.5 °C warmer than today (similar to what is expected in the coming decades should carbon emissions continue unabated), the Siberian Arctic temperature increased by more than 18 °C.
