Wed 24 Apr 17:30: Natural and forced behaviour of the Pacific Walker Circulation over the past 800 years Building doors are card operated, so latecomers may not be able to access the venue.
The Pacific Walker Circulation (PWC) is an important part of the global climate system, and affects weather and climate all over the world. However, our observational records of the climate system are too short to characterise the PWC ’s long-term internal variability, as well as how the PWC responds to external forcings such as volcanic eruptions and anthropogenic forcings.
In this seminar I will share a reconstruction of the PWC ’s behaviour over the past 800 years. I will outline how I calculated this reconstruction using a network of globally-distributed water isotope proxy records, as well as how I quantified uncertainties from different sources. I will share some new insights this reconstruction has allowed, including a close examination of the PWC ’s response to both volcanic and anthropogenic forcing.
Building doors are card operated, so latecomers may not be able to access the venue.

Wed 05 Jun 17:30: Extreme glacial implies discontinuity of early human occupation of Europe Building doors are card operated, so latecomers may not be able to access the venue.
The oldest known hominin remains in Europe [ca. 1.5 to 1.1 million years ago (Ma)] have been recovered from Iberia, where paleoenvironmental reconstructions have indicated warm and wet interglacials and mild glacials, supporting the view that once established, hominin populations persisted continuously. We report analyses of marine and terrestrial proxies from a deep-sea core on the Portugese margin that show the presence of pronounced millennial-scale climate variability during a glacial period ca. 1.154 to 1.123 Ma, culminating in a terminal stadial cooling comparable to the most extreme events of the last 400,000 years. Climate envelope–model simulations reveal a drastic decrease in early hominin habitat suitability around the Mediterranean during the terminal stadial. We suggest that these extreme conditions led to the depopulation of Europe, perhaps lasting for several successive glacial-interglacial cycles.
