The PEN is planning for its second General conference to take place in Leeds in the summer of 2018. The conference will gather members from around the world to discuss the network's themes from statistics to Palaeoclimate reconstructions.
The Data working group is holding the First UK Palaeoclimate Conference in Cardiff in September 2017. Further details, along with registration, will be available soon.
The Bayesian Inference in Stochastic Processes (BISP) meeting is a long running series of meetings which started in 1998. It attracts a statistical audience of people working in a mixture of theoretical and applied problems. The PEN session will include three talks from Andrew Parnell, Jochen Voss and Paul Blackwell on a mixture of palaeoclimate modelling topics from a statistical perspective.
The Past Earth Network (PEN) is happy to announce that it is able to provide some funding for the session "Marrying palaeo data records and paleoclimate modelling within a statistical framework" at the AGU Fall Meeting of 2016. This session is being convened by PEN Steering Committee members Alan Haywood (University of Leeds), Aisling Dolan (University of Leeds), Tamsin Edwards (Open University) and Emilie Capron (University of Copenhagen). The session covers inherent uncertainties surrounding the interpretation of proxy data (e.g. seasonal biases, age model uncertainties, geographical and temporal sparsity of records) and the simulation of past climates (e.g. inter-model differences and parameterisation uncertainty). The convenors welcome abstract submissions from any time period (especially pre-Quaternary) that address the following challenges: (1) Quantification of error and uncertainty in palaeo proxy records; (2) Quantification of uncertainty in complex models; (3) Methodologies which enable statistically robust model-data comparison, taking into account the nature and sparsity of data and model uncertainties; (4) Forecasting and future climate projections based on palaeoclimate analysis. AGU abstract submission opens on the 15th June 2016.
From 23-28 October 2016, the session titled 'Understanding Climate Variability in a warmer than present Pliocene World', organised by Ulrich Salzmann, Matthew Pound & Stijn De Schepper, will take place in Salvador Brazil. The session funded by the PEN, will address uncertainties in reconstructing past Pliocene environments by specifically focussing on the orbital to suborbital variability of climate and vegetation change throughout this geological epoch. Uncertainties caused by insufficient temporal data resolution have been identified by the PlioMIP 1 programme as one of the major constraints hampering an accurate data-model comparison. By focussing on variability in the available proxy-based data this session will address measurement errors, sampling uncertainty, calibration uncertainty, age uncertainty and spatial uncertainty, which are all key aims of the PEN data-working group. We also aim to bring together marine and terrestrial researcher, who often discuss their results in separated sessions/communities.
The PEN sponsored Ruza Ivanovic to attend Goldschmidt 2016 (Yokohama) and convene a session on ‘Tracing Ocean Circulation – Past and Present (session 16a). The session hosted 11 talks and 11 posters from scientists running climate models, measuring geochemical tracers of ocean circulation and using mathematical techniques to compare the measurements and simulations. The Past Earth Network and its upcoming workshop in Cambridge (September) was advertised on the session slide and in announcements. This is the first time a climate modelling theme has existed at Goldschmidt; a landmark in bringing together historically separate communities. As a result, there were many new faces at the conference, paving the way for exciting and fruitful new science. The session was so popular that there were often no spare seats, leaving standing room only for those later to arrive. A particular highlight was the impromptu session dinner, where 25 of the convenors, presenters and audience, most of whom had never previously met, spilled out of the over-running poster session and into a traditional Japanese restaurant. The key-note was given by Geoffrey (Jake) Gebbie, and invited speakers were Sandy Kirtland Turner, Daniel Lunt and David Thornalley. This was a very successful start to the enhanced model-data presence at the annual Geochemistry Conference, and a solid foundation for subsequent Goldschmidts – now looking ahead to Paris 2017!
At EGU2016 PEN sponsored a dinner which brought together over 25 climate scientists and statisticians from around the world. It gave people the opportunity to develop new collaborations and become newly engaged with the Past Earth Network. During the conference there were also a number of PEN related sessions including one co-convened by Dr. Aisling Dolan on “Antarctic palaeoclimates, sea level change and ice dynamics in past warm episodes: marrying models and data”. The session included talks on ensemble predictions of sea level rise based on Antarctic ice sheet modelling to statistical analysis of atmospheric dust content from ice core samples.
Dr. Julia Hargreaves also co-convened the session 'Paleoclimates from the Cretaceous to the Holocene: learning about past and future climate changes from numerical experiments and model-data comparisons'. The session focused on how modelling paleoclimates and the transitions between different climatic states still represents a challenge for models of all complexities.
We would like to the thank those that attended the PEN meeting during AGU Fall conference in San Francisco on 17 December 2015. The meeting was a well received rest-bite from the bustle of AGU with over 20 attendees from multiple research backgrounds. PEN will host more meetings in 2016 so keep an eye on the mailing lists for invitations.
