Project 2005P: Glacial terminations: processes and feedbacks

Details

We propose a Project that brings together the latest results from modelling and data acquisition/synthesis efforts for the previous two glacial terminations to understand the processes that shaped these two time periods. Glacial terminations occur when Earth transitions from cold glacial conditions, with much larger ice sheets as well as lower sea level and atmospheric carbon dioxide (CO2) concentrations, to warm interglacial conditions like today. This Project will bring together scientists with expertise in marine and lake sediment cores, speleothems, ice core records, sea-level changes, as well as climate and carbon cycle modelling to share their latest research in the field, work together on refining the sequence of events occurring during the last 2 terminations in under to understand the processes at play. The goal of the Project is to improve our knowledge of the feedbacks and processes occurring during the last two terminations, for which we have the best records as well as new syntheses of observational data and new multi-model simulations. The lasting impact of glacial terminations on the following interglacial period will also be studied.

An international congress will be organised as soon as the global health situation allows it. In the meantime, the IFG leaders and PAGES QUIGS leaders would like to hold two informal virtual meetings of ~two hours each. Abstract submissions for the upcoming QUIGS-IFG virtual meeting on glacial terminations (10/12 November 2020, http://pastglobalchanges.org/calendar/2020/127-pages/2054-virtual-quigs-20) is open until September 10th 2020, by filling the following form:

We invite submissions of studies that advance our understanding of glacial terminations, including changes in climate, carbon cycle, and sea-level based on numerical experiments or paleo-proxy records. We particularly encourage submissions from early career researchers and postgraduate students. Each meeting will be ~2 hours long, set so as to maximise participation from different time zones, and free of charge. Each presentation will be ~10-12 min long, followed by a few minutes for questions and discussion.
