Lifetime Achievement for Fritz

Details: Published: Thursday, 01 March 2018 14:59

A fantastic announcement has been made today by the International Paleolimnology Association (IPA) regarding PAGES' former Scientific Steering Committee member and co-chair Sheri Fritz.

"Put your hands together for Prof. Sheri Fritz, who will receive the Lifetime Achievement Award from the IPA! The award honors Dr. Fritz' career contributions to paleolimnology. She has accumulated a stellar record of achievement in the field of diatom taxonomy, biogeography, and paleo-environmental interpretation. Her work has had a wider impact across the fields of ecology, limnology, and paleoclimatology. She will receive the medal at the upcoming IPA meeting, which will be held in Stockholm, Sweden next June. Congratulations to Sheri on this well-deserved award!"

PALSEA Med Sea GIA paper

Details: Published: Monday, 26 February 2018 10:17

Members of PAGES PALSEA2 working group recently published "MIS 5e relative sea-level changes in the Mediterranean Sea: Contribution of isostatic disequilibrium" in Quaternary Science Reviews.

Paolo Stocchi et al. compare field data with numerical modeling to show that (i) glacio- and hydro-isostatic (GIA) adjustment is an important contributor to the spatial and temporal variability of the sea-level highstand during MIS 5e, (ii) the isostatic imbalance from the melting of the MIS 6 ice sheet can produce a >2.0 m sea-level highstand, and (iii) a two-step melting phase for the Greenland and Antarctic Ice Sheets reduces the differences between observations and predictions.

OC3: Top-10 in AGU journal

Details: Published: Monday, 19 February 2018 14:54

Congratulations to lead author Andreas Schmittner and the OC3 working group.

The paper "Calibration of the carbon isotope composition (δ13C) of benthic foraminifera" in Paleoceanography (an AGU publication) was one of the journal's top downloaded articles in recent publication history.

At the end of 2017, the article was in the top 10 with 914 downloads - an impressive achievement for the group's first product.

Hydrological variability in C.A.

Details: Published: Monday, 19 February 2018 11:37

A new contribution to the PAGES 2k Network Climate of the Past Special Issue reconstructs hydrological variability to determine flood and drought patterns on the Pacific coast of Central America between 1640 to 1945.

Led by Alvaro Guevara-Murua, the authors demonstrate the potential for assessing societal impacts by drawing on documentary sources from the cities of Santiago de Guatemala (now Antigua Guatemala) and Guatemala de la Asunción (now Guatemala City). Access the paper here.

Read about the latest PAGES' news, meetings and opportunities from around the world in this month's e-news.

Highlights include the launch of PAGES Early-Career Network, Scientific Steering Committee (SSC) members Pascale Braconnot and Darrell Kaufman being selected for the IPCC AR6, and upcoming deadlines for new working group and meeting support applications.

SSC members on IPCC AR6

Details: Published: Wednesday, 14 February 2018 14:20

PAGES Scientific Steering Committee (SSC) and Executive Committe (EXCOM) members Pascale Braconnot (France) and Darrell Kaufman (USA) have been selected for the IPCC Assessment Report 6 Working Group I.

Pictured at the 2017 SSC Meeting, Braconnot (middle row, white top) will be Review Editor of Chapter 8 and Kaufman (bottom row, far left) will be Lead Author in Chapter Two.

"The paleo perspective plays a key role in climate science and I’m honored to help represent our community in the IPCC process," said Kaufman. "I’m committed to integrating the paleo perspective into AR6 in a way that highlights the most policy-relevant aspects of our science – an opportunity that I’ve aspired to for many years."

Charcoal-based fire recons

Details: Published: Wednesday, 14 February 2018 10:55

The Global Paleofire Working Group 2 (GPWG2) discuss new opportunities for charcoal-based fire history reconstructions in a paper published today in the first issue of Fire.

Written by Julie Aleman, Andy Hennebelle, Boris Vannière, Oliver Blarquez and GPWG2 members, it is a product of the group's meeting in Montreal, Canada, in October 2017.
