We’re pleased to announce that we’re now inviting abstracts for the WWRP/WCRP S2S Summit at the University of Reading, UK, 3-7 July 2023.

Sub-seasonal to seasonal (S2S) prediction–2 weeks to a season ahead–is increasingly filling the gap between weather and seasonal climate forecasts, helping provide early warnings of high-impact events such as tropical cyclones, floods, droughts, heat, cold waves and their compound impacts on society. As the S2S forecast skill continues to improve through a better understanding of physical mechanisms involved, model advances and statistical calibration of model forecast outputs, more products are becoming available for decision makers to advance applications and services.

The Summit will celebrate the success of the WWRP/WCRP S2S Prediction Project over 10 years as it moves towards its completion in December 2023. The event welcomes contributions on all aspects of S2S science, including:

·       Physical mechanisms leading to predictability on sub-seasonal timescales,
·       Mddel evaluation and diagnostics,
·       Predictability and prediction studies,
·       Extreme events,
·       Traditional Model Output Statistics (calibration, verification) as well novel approaches such as, Machine Learning.
·       Examples and best practices of development, application, value and communication of S2S products.

Contributions making use of both the S2S and SubX databases are encouraged as these are complementary data sources for advancing sub-seasonal to seasonal prediction research. Forecasting of sub-seasonal weather statistics within the first season, including high impact weather and monsoon onset/cessation dates are also welcome.

The deadline for abstracts is 15th January 2023 and authors will be notified of abstract acceptance and presentation type by 28th  February. Abstract submission should be through the web-from on the conference website: https://research.reading.ac.uk/s2s-summit2023/

Meet with us in “Remarkable Rwanda”­­­­

The next WCRP Open Science Conference (OSC) will take place in 2023, with the major goal of bridging science and society by “advancing climate science for a sustainable future.” Climate risk, early warning, attribution, uncertainty, tipping points, irreversibility, and abrupt climate change are just some of the topics that will be discussed, both on a global and regional scale, as well as the fundamental science that is critical to advancing these important topics.­­­­­

Science leaders, politicians, policy makers, intergovernmental agencies and NGOs will share ideas on how climate research leads to a sustainable future. Natural and social scientists, humanities scholars, and practitioners from around the world will showcase their work, learn from each other, and explore new ways to work together to build the future we want. The OSC will feature the latest research from across the WCRP community (Core Projects, Lighthouse Activities, Grand Challenges) and from all of our key partners.

Together with the University of Massachusetts (UMass), Amherst, we are excited to invite applications for the position of Director of the Climate and Cryosphere (CliC) International Project Office (IPO). The position will remain open until filled, with a preferred start date of 1 March 2023. For full details and instructions on how to apply, please see the CliC website.

A draft version of the Fifth National Climate Assessment (NCA5) is now available for a 12-week public review and comment period. Additional information on this request can be found in the Federal Register Notice.

People who wish to review and comment on the draft report can do so via the USGCRP Review and Comment System (registration required). Instructions for comment submission are available on that site and in this brief recording and user guide .

In addition to this public comment period, NCA5 is being reviewed by a committee of the National Academies of Sciences, Engineering, and Medicine. All of the feedback received through these reviews will be considered by the chapter authors for future drafts of the assessment. The final version of NCA5 is expected to be released in late 2023.

This review is free and open to everyone. Please note that this is a draft document and it should not be cited, quoted, or distributed for purposes beyond this review.

ESA externally-hosted Climate Fellowships (10+ posts based in any hosting institutes in European Member States, 2-yr research proposals)

Closing date: 31 January 2023

The objective of this initiative is to support early-career scientists in the field of Earth Observation for Climate Research. To date the Climate Change Initiative (CCI) has funded 24 research fellowships to further improve and exploit Essential Climate Variable (ECV) products. To continue this research-excellence, ESA is calling for new proposals under the umbrella of the CCI Fellowship scheme. Host Organisation’s candidates shall propose a 2-year research plan contributing to at least one of the following areas: exploitation of the CCI ECVs to improve our understanding of carbon, water and energy cycles and investigate the long-term response of our climate system; cross-ECV research topics ranging from (but not exclusive to) teleconnections, tipping points, ice-ocean- atmosphere interactions, ocean surface currents, sea level budget closure, atmospheric trace gases, land- atmosphere exchange, terrestrial hydrology, and climate and human health; topics related to the exploitation of CCI ECVs in the context of Coupled Model Intercomparison Project (CMIP). Full details can be found at this link https://climate.esa.int/en/esa-climate/esa-cci/fellowships/call-for-research-fellowship-proposals/

The international Commission for Atmospheric Chemistry and Global Pollution (iCACGP) is calling for nominations for new members and officers to its Scientific Commission. iCACGP advocates for research into atmospheric chemistry to address questions in all parts of the atmosphere, as well as the interfaces of the earth system with the atmosphere (ocean interface, land interface, stratosphere interface). This is achieved through promoting understanding of the fundamental mechanisms that control atmospheric composition and the development of improved predictive capabilities. This requires measurement, laboratory studies, and modelling. iCACGP is one of the Commissions in IAMAS (International Association of Meteorology and Atmospheric Sciences), which in turn is one of the associations within IUGG (International Union of Geodesy and Geophysics) under the non-governmental ICSU (International Council for Science) family.
