PAGES congratulates the 2k Network working group as the PAGES Executive Committee approves continuation into Phase 4!
The first three phases of the PAGES 2k Network generated global paleotemperature record that were critical to the IPCC Sixth Assessment Report (AR6). However, the AR6 also highlighted that hydroclimate-related variables across CMIP6 projections still have notable uncertainty and regionally low agreement between models.
The 2k Network Phase 4 will therefore focus on providing hydroclimatic data to constrain models that are used to simulate future changes, while using these same models to provide dynamical understanding of past hydroclimate. This is critical for enhancing understanding of hydroclimate changes over the Common Era, including quantification of the influence of changes in oceanic and atmospheric circulation patterns on regional hydroclimate.
The 2k Network has four main objectives providing focus for Phase 4 activities:
1. Reconstruct spatial and temporal hydroclimate variability and change over the Common Era from local to global scales;
2. Evaluate and constrain Earth system models using hydroclimate proxy data, whilst using models to inform process-level understanding of Common Era hydroclimate;
3. Develop tools and practices to maximize interoperability of 2k data products, including data sets from earlier phases; and
4. Translate the science into evidence-based policy outcomes.
More details on these objectives will be published in the coming weeks. If you are interested in any of these research themes, then please keep an eye out in future newsletters and announcements, as the 2k Network will be soliciting for involvement.
In particular, they are actively seeking people involved in climate policy and climate services: if this is you, then please get in touch!
Along with the new phase of the 2k Network comes a new coordination team! The group welcomes Alyssa Atwood (Assistant Professor, Florida State University, USA), Georgy Falster (Postdoctoral Fellow, Australian National University, Australia), Ben Henley (Lecturer, Monash University, Australia), Matt Jones (Professor, University of Nottingham, UK), Lukas Jonkers (Postdoctoral scientist, MARUM, Germany), Anaïs Orsi (Assistant Professor, University of British Columbia, Canada), and Hussein Sayani (Senior Scientist, SLR Consulting, USA), who will join previous 2k coordination team members Nikita Kaushal (Postdoctoral Research Fellow, ETH Zürich, Switzerland) and Helen McGregor (Associate Professor, University of Wollongong, Australia) to steer Phase 4 through the next three years.
