Abrupt changes in climate and ice sheets during glacial-interglacial cycles: INQUA July 2019 Dublin

Lauren Gregoire

Dear colleagues,

 

We would like to draw your attention to our session on ‘Abrupt changes in climate and ice sheets during glacial-interglacial cycles’ at the forthcoming INQUA Congress, 25-31st July 2019, Dublin. The session aims to address the cause and consequences of forced/unforced climate and ice sheet events in the Quaternary and we welcome a diverse range of abstract submissions on this theme.

 

Details are copied below and the abstract deadline is 9th January (http://www.inqua2019.org/call-for-abstracts/).

 

Please pass on this message to your research groups and anyone else who you think would be interested to attend. It’s shaping up to be a great conference!

 

Best wishes,                                                            

Lauren
[On behalf of the session convenors: Ruza Ivanovic, Lauren Gregoire, Laura Robinson]

ABRUPT CHANGES IN CLIMATE AND ICE SHEETS DURING GLACIAL-INTERGLACIAL CYCLES

 

Understanding how and why rapid environmental changes took place in the Quaternary remains a key challenge in the field of climate science. In particular, it remains difficult to reconcile the chain of events between recorded warming, cooling, iceberg calving, ice sheet melt and sea level rise. Many of these events have been linked with changing greenhouse gases, collapsing ice sheets and rapid reorganisations of ocean circulation. However, the fundamental questions remain: How can progressive climate trends trigger rapid changes? What are the internal instabilities and ice-ocean-atmosphere interactions that drove the sudden transitions? Are they stochastic responses in a variable Earth System or are the processes consistent across glacial-interglacial cycles? What was their environmental impact?

 

For this session, we invite contributions that seek to better constrain the chain of events surrounding abrupt changes in climate and ice sheets during glacial-interglacial cycles. We encourage submissions covering mechanistic-modelling, data acquisition and reconstructions of the events and their impact.

 

INVITED SPEAKERS:

- Ayako Abe-Ouchi (University of Tokyo)

- Andrea Burke (University of St Andrews)

- Victor Tsai (California Institute of Technology, Caltech)
