Reconstructing climate

Reconstructing climate from Late Glacial subfossil trees
Wednesday 7 October, 2020 – Wednesday 7 October, 20203:00 PM – 5:00 PM
Online
Part of the Hazard, Risk and Disaster (HRD) Research Seminar Series 2020-21.
Significant attention in paleoclimate research has focused on the transitional period between the last glaciation and the current Holocene interglacial, known as the Late Glacial (LG: ~14,000 – 11,000 calendar years before present (cal BP)). In the northern hemisphere, the gradual warming was interrupted by numerous cold episodes, including a significant reversal to near glacial conditions known as the Younger Dryas (~12 900 – 11 700 cal BP) as evidenced in Greenland ice core and European lake records.
In this talk, Maren Pauly discussed this intriguing climate period recorded in high-resolution subfossil tree-ring stable isotopes (δ18O, δ13C), as well as subsequent reconstructions of relative humidity and precipitation. Regional disparities and drivers in rate and magnitude of LG climate events were also discussed.
