Session Description:
The impact of Polar hydroclimate change is not only local, but also global through various feedbacks and teleconnections. However, a lack of spatiotemporal observations makes quantification and understanding of Polar hydroclimate difficult. Paleoclimate proxies can provide more holistic views of past hydroclimate in these regions. Moreover, new methods enable tracking of both amount and source of local precipitation. Progress in the use of isotopes and other proxies have enhanced our understanding of how major shifts in atmospheric circulation patterns affected hydroclimate in the past. Also, co-development of numerical approaches, successfully integrating models and experimental data, has made it possible to link hydroclimate variability to shifts in the atmospheric water cycle in a long-term context. This session aims at highlighting recent progress on Polar and Subpolar hydroclimate in a paleoclimate context, bringing together proxies, data syntheses and model simulations. Contributions exploring the mechanisms behind Polar hydroclimate variability are particularly welcome.
