During summer 2010, exceptional heat and drought in western Russia (WRU) occurred simultaneously with heavy rainfall and flooding in northern Pakistan (NPK). Here, we use the Great Eurasian Drought Atlas (GEDA), a new 1,021 year tree-ring reconstruction of summer soil moisture, to investigate the variability and dynamics of this exceptional spatially concurrent climate extreme over the last millennium. Summer 2010 in the GEDA was the second driest vear over WRU and the largest wet-dry contrast between PK and WRU; it was also the second warmest year over WRU In an independent 1,015 year temperature reconstruction. Soil moisture variability is only weakly correlated between the two regions and 2010 event analogues are rare, occurring in 31 (3.0%) or 52 (5.1%) years in the GEDA, depending on the definition used. Post-1900 is significantly drier in WRU and wetter in NPK compared to previous centuries, increasing the likelihood of concurrent wet NPK-dry WRU extremes, with over 20% of the events in the record occurring in this interval. The dynamics of wet NPK-dry WRU events like 2010 are well captured by two principal components in the GEDA, modes correlated with tropical Pacific ocean temperatures and a pan-hemispheric extratropical wave train pattern similar to that observed in 2010. Our results highlight how jigh resolution paleoclimate reconstructions can me used to capture some of the most extreme events in the climate system, investigate their physical drivers, and allow us to assess their behavior across longer timescales than available from shorter instrumental records.
