2. Past Global Changes Horizons

In June, PAGES will be publishing its new, annual Past Global Changes Horizons magazine aimed at teenagers and young adults. This magazine is a scientific review of why the study of Earth’s history is important, and uses comics, pictures, and drawings that support short papers with strong messages about past sciences and how to prepare for a changing future. Articles cover different environments across the planet. If you would like to order a free hard copy of the magazine, please fill in your details here. The deadline to complete the order form is 30 June. More information on ordering a free hard copy will be forthcoming in the June newsletter. > Access volume 1 

3. Mobility Fellowships for African, Latin American and Caribbean early-career scientists

The call for applications for both the PAGES-IAI fellowship program aimed at Latin American and Caribbean early-career scientists and the Inter-Africa mobility program aimed at African early-career scientists is now open. Deadline for applications is 19 August. > More information 

4. Congratulations to Prof. Martin Grosjean

PAGES would like to congratulate Prof. Martin Grosjean, PAGES SSC member, and Director of the Oeschger Center for Climate Change Research, on being elected as a member of the National Academy of Sciences Leopoldina (Germany). "The Leopoldina is the oldest scientific society in the German-speaking world and the oldest permanently existing academy of natural sciences in the world. It has around 1,600 members." > Oeschger Centre website

5. Working group news

i. Mailing lists
Did you know all PAGES working groups have designated mailing lists? Stay up to date directly. > Details for all mailing lists

ii. Carbon in Peat on Earth through Time (C-PEAT)
Over 70 peat proxy datasets have been received thus far for the C-PEAT paleo database, and at least 50 more are expected shortly. C-PEAT data steward, Dr. Nicole Sanderson, assisted by undergraduate student Kendahl Hejl, have begun harmonizing the datasets for integration in Neotoma. You can still contribute to this effort and have your proxy data harmonized and published on Neotoma, and of course become co-author of community papers that will ensue. For more information, please contact show mail address or Nicole show mail address.

iii. Cycles of Sea-Ice Dynamics in the Earth system (C-SIDE)
a. Green et al. have published “Evaluating seasonal sea-ice cover over the Southern Ocean at the Last Glacial Maximum” in Climate of the Past. The authors analyzed Southern Ocean (SO) winter sea-ice (WSI) and summer sea-ice (SSI) cover in Last Glacial Maximum (LGM) simulations. These outputs were then compared against available proxy reconstructions. The authors identified "the potential drivers for intermodel Southern Ocean sea-ice differences, in addition to placing improved constraints on the LGM SO SSI and WSI extents. This improved understanding of sea-ice dynamics can provide valuable information about the earth's system and important insights into the strengths and weaknesses of models currently used." > Article 
b. The group is preparing the Climate of the Past special issue "Reconstructing Southern Ocean sea-ice dynamics on glacial-to-historical timescales". The deadline for submissions has been extended until 31 December 2022. > More information  

iv. Climate Variability Across Scales (CVAS)
a. CVAS leaders are planning a joint CVAS-PAGES2k meeting on regional variability at the centennial timescale. The group would like to implement this as a summer meeting in person (maybe incl. hybrid). Please get in touch with the CVAS leaders if you are interested in helping with the physical and/or scientific organization. > Contact leaders  
b. The group is also planning a new CVAS seminar series, with a focus of the former Paleoclimate Reanalyses, Data Assimilation and Proxy System modeling (DAPS) working group. In this series, they hope to cover all areas of proxy system modeling which have been developed up until now. If you want to help with the organization of the seminar, or have expertise in proxy system modeling and wish to contribute a discussion or talk, please get in touch with the group leaders. > Contact leaders 

v. Human Traces
The next webinar in the Human Traces seminar series will take place on 15 June with Prof. Nicolas Waldmann (University of Haifa, Israel) on “The Levantine corridor: a land bridge for early hominins migrations out of Africa and the birthplace of agriculture”. > Calendar

vi. Understanding past ecological trends (PaleoEcoGen
The recoding of the final seminar in the series for this semester, which took place on 21 April, is available to watch. The seminar was hosted by Dr. Allison Stegner (Postdoctoral Scholar, Department of Biology & Jasper Ridge Biological Preserve, Stanford University, USA) on "Tracking abrupt ecological change in the Quaternary fossil record". > Watch 

vii. Paleo constraints on sea level rise (PALSEA)
a. Daltona et al. have published on "The marine δ18O record overestimates continental ice volume during Marine Isotope Stage 3" in Global and Planetary Change. According to the authors, "This work urges caution regarding the reliance of the marine δ18O record as a de facto indicator of continental ice when few geological constraints are available, which underpins many Quaternary studies." > Article
b. The group have announced the final dates of their PAGES-supported workshop "Paleo Sea Level and Ice Sheets for Earth's Future". The workshop will take place from 17-20 July in Joyden hall, Singapore, and will include a hybrid option. The deadline for abstracts is 6 June. However, if you are an ECR or DCR, or require an acceptance/invitation letter in order to proceed to book travel, the deadline for abstract submission is 16 May. > Calendar 

viii. Pliocene and Miocene climate variability over glacial-interglacial timescales (PlioMioVAR
Abstract submission for the Galileo Conference titled “The Warm Pliocene: Bridging the geological data and modelling communities Conference (23-26 August 2022, Leeds, UK)” closes on 12 May. > Submit abstract 

ix. Disentangling climate and pre-industrial human impacts on marine ecosystems (Q-MARE)
a. Agiadi et al. have published a paper on “Potential and limitations of applying the mean temperature approach to fossil otolith assemblages” in Environmental Biology of Fishes. In their study, the authors explore the applicability of the mean temperature approach to fossil fish faunas by using otolith assemblage data from the eastern Mediterranean and the northern Adriatic coastal environments of the Holocene and Early Pleistocene. Their findings show that the mean temperatures of the otolith assemblage "can successfully capture compositional shifts in marine fish faunas based on variations in their climatic affinity driven by regional climate differences. However, the index is sensitive to methodological choices and thus requires standardized sampling." > Article 
b. The group has launched a monthly online seminar series which will be held approximately the first Wednesday of every month. The series aims to cover all fields of interest to the working group and community, and all are welcome. The first seminar took place on 4 May with Dr. Susan Kidwell on "Where we are and what’s next in understanding the nature of ordinary shallow-marine fossil records”, and the recording is available to watch. Further seminars have also been announced. > Watch 

x. PAGES-PMIP Working Group on Quaternary Interglacials (QUIGS)
In their most recent paper on "Marine Isotope Stage 11c: An unusual interglacial" in Quaternary Science Reviews, authors Tzedakis et al. "trace the characteristics of MIS 11c and explore their most likely causes. MIS 11c was preceded by the largest Quaternary ice volume expansion of MIS 12, which ended with a long period of ice rafting and interhemispheric heat transfer." Further, the authors suggest that "the duration of MIS 12 and the size of ice sheets exceeded a critical threshold that triggered a deglaciation despite the weak insolation forcing. " > Article 

xi. Speleothem Isotopes Synthesis and Analysis (SISAL)
The group would like to thank everyone who attended the recent seminar by Jasper Wassenburg on “Trace elements: partitioning in speleothem calcite and aragonite and their control on mineralogy”.
For those who were not able to attend or want to review some of the content, the recording of the talk is now available on the PAGES YouTube channel. > Watch 

6. PAGES Early-Career Network (ECN)
i. The ECN are looking for new regional representatives to join the PAGES ECN community. If you, or someone you know, is interested in fostering collaboration and promote the work of early-career paleoscientists around the world, please apply. > Apply 
ii. The PAGES-INQUA joint ECR workshop: Past Socio-Environmental Systems (PASES) will be taking place from 20-24 November in La Serena, Chile. The workshop aims to facilitate scientific exchange between early-career researchers (ECRs) from a broad range of disciplines that work within the overarching theme of climate-environment-cultural change, which is at the core of both PAGES’ and INQUA’s missions. Innovative ideas and approaches that tackle multiple hypotheses of changes where human, environment and climate interact at different temporal scales and across different geographies are welcome. Registration opens on 2 June and closes 15 July. > Calendar

a. The DEEPICE project has launched a 7-minute video which features interviews from the project participants. It also provides a fascinating overview of the project, with some mesmerizing footage of the site in Antarctica. > Watch
b. There will be a DEEPICE Training school on Statistical and modelling tools in Bremerhaven, Germany from 19-23 September. It will focus on statistical and modelling tools used for ice cores analysis. In particular, students will attend courses on time-series analysis with application to existing ice core data, as well as introduction to climate modelling dynamics, coupled ocean-atmosphere-ice climate models and ice dynamics processes. All details will be made available on the DEEPICE website. > Website

ii. Ice Core Young Scientists (ICYS)
a. The 15th seminar in the ICYS series was held on 3 March with Jeff Severinghaus (SCRIPPS, UC San Diego, USA) on “Mean ocean temperature reconstructions based on noble gas ratios” and Markus Grimmer (University of Bern, Switzerland) “MIS5-6 mean ocean temperature data from the EDC ice core”. The recordings are now available to watch on the ICYS page. > Watch 
b. The next seminar will take place on 19 May at 14:00 UTC with Margit Schwikowski, PSI on "Environmental changes from glacier ice cores and the ICE MEMORY initiative” and  Carla Huber, PSI on “Recent accelerated melting endangers high-mountain glacier archives". > Calendar 

iii. LandCover6k 
a. Githumbi et al. have published a new paper in Earth System Science Data on “European pollen-based REVEALS land-cover reconstructions for the Holocene: methodology, mapping and potentials”. The authors present “the first temporally continuous and most spatially extensive pollen-based land-cover reconstruction for Europe over the Holocene.” > Article
b. Sun et al. have published on “Pollen-based reconstruction of total land-cover change over the Holocene in the temperate steppe region of China: An attempt to quantify the cover of vegetation and bare ground in the past using a novel approach” in CATENA. Sugita’s REVEALS model is the best method to estimate regional plant cover using pollen data from lakes. However, these reconstructions suggest that the sum of all plants’ cover is 100%. However, as the authors point out, "land cover is not always represented by vegetation alone, the area of bare ground can be significant in many types of biomes, e.g., in alpine or steppe regions." In their paper, the authors propose a novel strategy to reconstruct the regional land-cover from pollen data. The results suggest that the method provides plausible estimates of vegetation cover for the sub-regions within the study area. > Article 
c. Wan et al. have published in Quaternary International on "Regional land cover changes of the last 6,500 years in middle and southern subtropical China". This paper is very exciting because it is the first application of the REVEALS model in the tropics with validation of the application using modern pollen/vegetation data. > Article 
d. There will be a Special Issue of Climate of the Past on "Past vegetation dynamics and their role in past climate changes". Manuscripts can be submitted until December 2024. If you are interested in submitting your manuscript, please first contact one of the guest editors. All information is available in the pdf. > Download pdf 

iv. Ocean Circulation and Carbon Cycling (OC3)
