At the European Plate Observing System (EPOS) Townhall, the EPOS Research Infrastructure introduces to the scientific community its novel Data Portal: an innovative, unique and sustainable platform for cross-disciplinary research in Solid Earth Science. The key moment will be represented by the presentation of scientific use cases based on the EPOS Data Portal, by two young researchers.

A new science movie frames a scientific question as a murder investigation: who "killed" (meaning weathered) rocks altered in deep weathering zones along a climate gradient in Chile? Detective Hercule Poirot looks for alibis for the suspects: rock fractures, water flow, chemical reagents, or microbes. He engages geologists, geochemists, geophysicists, and microbiologists for a drilling campaign in spectacular landscapes in Chile and in their home laboratories. The movie, produced by the german-chilean ''EarthShape'' project, also shows animations of the processes deep beneath Earth’s surface. The movie show is 30 minutes, followed by a townhall discussion of its scientific questions and approaches for communicating complex science to a general public.

Almost one year has passed since the foundation of the European Space Weather and Space Climate Association (E-SWAN, eswan.eu). E-SWAN is the legacy of the "Quo Vadis, European Space Weather Community?" initiative, which was initiated during the harsh pandemic times to give the Space Weather and Space Climate community the possibility to take a major step forward in mapping out its future. In that initiative, the working groups were established to investigate the best next steps, related to the technical, statute, legal, and funding aspects of creating a new organisation.
The ambitious mission of E-SWAN is to unite, sustain, and develop Space Weather and Space Climate activities in Europe. E-SWAN will immediately be the natural host for the European Space Weather Week, for the Journal of Space Weather and Space Climate, and for the International Space Weather and Space Climate Medals.

The purpose of this session, organized by the first elected Executive Board of E-SWAN, is to inform the scientific community about the E-SWAN plans and concrete actions to fulfil its mission and to collect feedback from the community. This meeting is open to the community at large, including stakeholders, forecasters, scientists, product providers, and is open to members from any country throughout the world, although one needs to work in Europe to belong to the Executive Board. E-SWAN is also willing to liaise with all other existing bodies involved in space weather and space climate activities worldwide.

The evaluation of climate future scenarios and the assessment of their plausibility is of utmost importance for climate discourse, climate action, and decision-making processes at large. Possible climate future scenarios are often considered side by side on an equal footing. Some existing reports explore feasible climate future scenarios, where feasibility is defined as “the potential for a mitigation or adaptation option to be implemented” (AR6 SPM WGIII). What is not assessed is whether it is plausible that certain mitigation or adaptation options are going to be implemented. Indeed, a feasible pathway may not necessarily be plausible; we interpret plausibility loosely in the sense that implementation can realistically be expected. In the Hamburg Climate Futures Outlook, we show that assessing the plausibility of climate futures involves analyzing the social and physical dynamics that influence the pathways toward or away from a specific climate future scenario. This approach to climate futures research is unique in its combined focus on social and physical dynamics.
In this Townhall Meeting we present the CLICCS Plausibility Assessment Framework, established in the 2023 Outlook edition to assess the plausibility of worldwide deep decarbonization by 2050 and of staying below the 1.5°C limit to global warming. More than 60 social and natural scientists have analyzed the dynamics of the ten dominant social drivers of decarbonization and of six select physical processes of public interest. The physical processes where selected on the basis of one or more of the following criteria: (i) the process is veiled in deep uncertainties, (ii) the process is a potential tipping element, (iii) or the process receives much attention in the public discourse shaping climate risk perception. This Townhall Meeting aims to engage participants in an open discussion on feasibility vs. plausibility in climate futures research and on the implications of our approach and findings.

This Townhall Meeting aims to give an outlook of new directions in scientific research that could be possible if online data sets, tools, and research infrastructures are fully integrated on a global scale across scientific disciplines as well as sectoral and national boundaries.

Looking up to the sky: Flying around in the Open Science Universe, we identify what is already there – what can we reach with our scientific starships and how can we benefit? What spectacular scientific results can we foresee with Open Science approaches? What would be needed to achieve them?

Looking back down to earth: We identify the current barriers or challenges and brainstorm ways to overcome them. What does this require from all of us and our current way of thinking about integrating data and science? How can we boldly go where no scientist has gone before?

This Townhall Meeting follows up on the session ESSI 2.9 where various approaches demonstrate successful integration on the level of datasets and/or research infrastructures in support of scientific research. Within disciplines, across disciplines, and across national or even continental boundaries.

Although it may seem like a small step in this day and age of great online and technological possibilities, early attempts hint that it will still be a giant leap to fully achieve this integration.

In December 2022, the new Copernicus Data Access Service was kicked-off by ESA, taking the European Union Copernicus program to the next level and ensuring the data to make the greatest possible impact to institutional users, the research community, the commercial sector as well as to every citizen of our planet.

The new service will become widely available in April 2023 and will be fully operational in July 2023 after a progressive phase-in period corresponding to the phasing out of the current data distribution service, leaving time for users to migrate and familiarise themselves with the new service interfaces. Copernicus is also pursuing full interoperability with the Destination Earth future data infrastructures as well as with Member States' earth observation data infrastructures.

The following topics will be addressed during the Townhall Meeting:
- How is the new service different from current Copernicus OpenHub?
- How will the Copernicus data delivery and analysis landscape change?
- What “immediately available data” really means and how can this affect the way EO data is used by the community?
- How will the science community benefit from the new service?
- Download from OpenHub is free, cloud services on Copernicus DIASes are payable – how is it going to be organized in the new Copernicus Data Access Service?

NASA and ESA are currently planning a Mars Sample Return (MSR) Campaign to return samples from Mars safely to Earth for scientific research. The Mars 2020 mission is the first element of this MSR Campaign and has already collected a scientifically return worthy set of samples on Mars. Three of the five guiding principles for the MSR science management are: transparency, scientific maximization and accessibility. Following these principles, NASA and ESA are planning several opportunities for the international scientific community to participate in the planning and execution of MSR science. This Townhall will describe the samples already acquired on Mars, planned research & development activities, and upcoming opportunities for the international science community. One part of the Townhall is based on presentations, while a second part is based on open discussions and questions from the audience. Three speakers and one moderator will participate in the Townhall.

An ongoing challenge in some research communities is the difficulty in properly citing 100+ digital objects such as datasets, software, samples, and images that might all be assigned with individual digital object identifiers (DOIs). Journals commonly push authors to place citations over some set limit into the supplemental information, where the individual citations are not properly indexed, not linked to the manuscript, nor tracked accurately. This is critical to (1) enable reproducible research and (2) for researchers, institutions, and project managers to be able to trace citation and usage of their work, get appropriate credit, and report on impact to funders.

We propose the term ‘reliquary’ to describe aggregated individual objects used to form a dataset for a specific paper. A reliquary may contain hundreds to millions of objects, often provided by different research groups and stored in different repositories. Citations may need to include subsets of objects from multiple collections. Credit needs to be directed to the creators and funders of individual digital objects in the collection and we need to develop a scalable implementation strategy. This includes the development of both infrastructure and best practice guidelines to make it easier for researchers to use this type of citation and allow integration into common citation metrics as an established credit system for research.

In this Townhall we invite everyone interested to join the effort and work towards a community-agreed solution. Initial work has started in 2019 with a tenacious group of researchers, repositories managers, infrastructure, journal staff, and indexers to define the problem as well as outline a basic approach that applies to most situations and develop early drafts of the recommendations. We want to engage with the broader community, identify more use cases and ask for your feedback and support to finalize these recommendations and identify adopters. The work is related to the new working group “Complex Citations” of the Research Data Alliance. All are welcome to participate in this townhall and join the working group: https://www.rd-alliance.org/groups/complex-citations-working-group.

The paradigm of Open Science is based on the tiers of Open Access, Open Data, and Free Open Source Software (FOSS). However, the interconnections between the tiers remain to be improved. This is a critical factor in enabling Open Science as a context where researchers, especially the younger ones, can express their potential thanks to a scientifically healthy practice.

This townhall meeting focuses on discussing best practices not only on using Free Open Source for geospatial but its developments and support, and how extra efforts required to publish not only the results can be recognized as part of the work of a scientist.

Deep-time Digital Earth (DDE) is the first Big Science initiative of the International Union of Geological Sciences (IUGS) dedicated to facilitating innovation in understanding Earth’s evolution – life, climate, materials, geography – by using Big Data analytics, internet cloud computing, data mining, machine learning and AI.

DDE World Cup 2023 will be launched as a global competition for young and early career geoscientists in earth, geodata, and geoinformatics science to promote data-driven, geoscientific research in the DDE Platform environment. The competition is organised by the DDE Young Earth Scientists and Geo-education Task Groups together with the Global Young Earth Scientist (YES) Network.

The competition will be open to all young and early career geoscientists as a two-round selection of the global winners. The competition rules and judgment criteria will be announced at a Town Hall meeting on 27 April 2023 at EGU2023, where the DDE World Cup 2023 competition will be officially initiated.

Finalists comprising winners from the first-round and the global winner and runners-up will be invited to a DDE sponsored global event to receive their awards

About DDE
DDE is a large-scale Earth science initiative, supported by a several Members comprising geo-surveys and geo-research organizations. The DDE Platform was officially launched at the recent DDE Open Science Forum on 9 November 2022 which attracted many international attendees and was co-organized by UNESCO, IUGS, and IYBSSD and DDE at the UNESCO Headquarters in Paris, France.

"The time for climate action is now. Science is critical in shaping the policies and actions to tackle the global climate change challenge,” said Chair of the IPCC Hoesung Lee.

We are living in a climate emergency. Anthropogenic greenhouse gas emissions have raised the average global air temperature already by about 1°C above pre-industrial levels. Considering our current emissions pathways, the temperature increase could reach 1.5°C by 2030. And yet, little action has taken place to actually reduce our CO2 emissions. On top of this, Sultan Ahmed Al Jaber, Chief executive officer of the Abu Dhabi National Oil Company, will lead the COP28 global climate talks in Dubai later this year. And a recent study in Science showed that Exxon precisely predicted already in the 1980s how the world is warming due to fossil fuel burning, yet being a global leader in climate change denial. And in fact, more and more scientists have the feeling that presenting the facts is not enough.

In this Town Hall meeting we would like to share different perspectives from the geosciences community on how we perceive the contrasting pace at which we produce knowledge and its implementation into policy change. How can we, as scientists, more effectively advocate for a rapid transition to a low-carbon future and secure a liveable and sustainable future for all?
If you would like to learn more about scientist rebellion and are interested in getting active, do not miss the splinter meeting SPM70 "Science and Climate activism (part 2): How to get involved (with Scientist Rebellion)?" on Friday at 12:45 in room 2.61.

Over the past few years we have learned some valuable lessons as a scientific community: we are stronger together; we must uplift one another in order to achieve scientific progress; and the best solutions are found when we work together. But these lessons will be unable to spread far unless we begin to address the hesitancy in transitioning towards sharing data and results and the lack of applied experience with tools which make open collaboration easier. Transform to Open Science (TOPS) is a new NASA Science Mission Directorate mission designed to spark a cultural shift to collaborative, inclusive science.

Open science increases access to knowledge and expands opportunities for new voices to participate. Sharing the data, code, results, and knowledge associated with the scientific process lowers barriers to entry for historically-underrepresented communities, enables findings to be more easily reproduced, and generates new knowledge at scale. Success, however, depends on all of us working to change the frameworks from which we operate.

Through this townhall, we will showcase success stories in the Earth and space sciences and highlight a range of open science platforms, datasets, and computational tools. Join this townhall for real-world examples of how open science practices have empowered and enabled scientists across disciplines to carry out successful research projects.

The state of the planet, especially climate and ocean, is moving towards catastrophe almost by the day. Just two, from among many 2022 quotes illustrate the enormity of the problem.
• Our world is suffering from the impact of unprecedented emergencies caused by the climate crisis, pollution, desertification and biodiversity loss. UN Secr-General, Guterres.
• Multiple climate tipping points could be triggered if global temperature rises beyond 1.5°C above pre-industrial levels. This will be disastrous for people across the world. futureearth.org & Rockström.
Is the problem so wicked that we are going, or have already gone, beyond the point of no return? Is extinction inevitable?
So many people, so many organizations, local, national and international, through companies (eg, insurance) and the military, up to the UN, indicate that they are successfully tackling the problem of climate change, and yet GHG emissions and temperatures continue to rise. Why?
Can we swing the needle back towards a lower risk of catastrophe? Who is ‘we’? How do we swing the needle back? What kind of communication is effective? What policies, education, research, geoethics and actions are needed and realistic?
This are some of the questions that panel speakers and participants are invited to discuss and debate. The aim will be to move forward in our climate change and ocean realism, even if it is tentative. The aim is to develop some kind of consensus on the idea; still expressed by some, that it is still possible – realistically – to move the needle back. If not, then what?

Forests are at the forefront of our efforts to mitigate climate change and achieve the UN’s Sustainable Development Goals to ensure a sustainable life on Earth. However, forest ecosystems are particularly threatened by global change components, such as more frequent climate extreme events and changes in atmospheric pollutants (namely carbon dioxide, reactive nitrogen and sulphur compounds). All these factors strongly influence the capacity of forests to continue providing important ecosystem services we rely on, including climate regulation and mitigation, biodiversity conservation, clean water and air supply, food and energy production, and improvement of human health and well-being, particularly in urban systems. Different global change drivers could play a synergistic, antagonistic or predisposing role in affecting forest ecosystem functioning and health. All these drivers, however, are generally considered in isolation, and their effects on key processes (at tree, soil and ecos ystem levels) are investigated separately in natural, periurban and urban forests, thus leading to uneven, un-coordinated and scattered information among different research communities.

The recently funded COST Action CLEANFOREST has the ambition to overcome such fragmentation by capitalising on existing expertise and infrastructures available at the pan-European level (monitoring and manipulation experiments) to i) coordinate efforts and ii) foster exchange of information and collaborations among different research communities and relevant stakeholders along the natural-periurban-urban forests continuum. This will promote and ensure that robust methods addressing issues of forests under global change are adopted at large scale, and that policies are underpinned by robust science.

This Townhall meeting will be an excellent opportunity to learn about the CLEANFOREST COST Action, Challenges and WG activities planned for the next 4 years, networking and training opportunities, particularly for early career researchers. The meeting seeks to engage with the broader scientific community within the EGU Atmospheric Science, Biogoesciences, Geosciences Instrumentation and Data Systems and Soil System Sciences Divisions so to widen participation to other research fields/expertise. We welcome to the discussion researchers at any stage of the their careers involved in monitoring and/or manipulation experiments as well as in bridging science and policy to address societal challenges. The meeting will open with a short and dynamic presentation of the COST Action (Challenges, Structure and activity plans), followed by an open and engaging discussion with the attendees.

Speakers: Chair of the Action (Rossella Guerrieri, University of Bologna, Italy), Science communication Coordinator (Katerina Machacova, CzechGlobe - Global Change Research Institute Czech, Czech Republic) and WG leaders and/or co-leaders (TBD).

For almost half a century, satellites have delivered the global view, revolutionizing Earth system science and spearheading European environmental protection efforts. In the face of growing societal impacts resulting from a changing climate, how is the space sector responding?

Following a contemporary performance to showcase new and novel Earth observations, a panel drawn from the European Space Agency and its partners - UNFCCC, GCOS, WCRP, EUMETSAT and ECMWF - will discuss the role that candidate Earth Explorers research missions and the Copernicus Sentinel extension satellites can play in strengthening Earth system science. The panel will address the causes, and build resilience to, the negative consequences of environmental change.

The Agency will also unveil and highlight opportunities for community engagement with its new climate initiative, CLIMATE-SPACE. Harnessing European expertise, this major R&D effort aims to expand and improve the suite of satellite derived-climate data records used to characterize the Earth system and support ESA Member States’ progress towards delivering national and regional commitments towards the UNFCCC Paris Agreement.

The primary objective of the World Climate Research Programme’s (WCRP) Coupled Model Intercomparison Project (CMIP) is to better understand past, present, and future climate changes arising from natural, unforced variability or in response to changes in forcing in a multi-model context. Successive generations of CMIP have seen the project grow in scope, with increasing process-specific Model Intercomparison Projects (MIPs) developed to better address new and focused scientific questions, while continuing to play a critical role in the IPCC Assessment Reports. The latest phase, CMIP6, was the biggest yet with 131 participating models from 48 institutions, representing 26 countries around the globe, and nearly 25 PB of CMIP6 data now available across the 30 plus Earth System Grid Federation data nodes.

Looking forward, the CMIP Panel and World Climate Research Programme (WCRP) are beginning work on designing the next phase of CMIP, CMIP7. For this, we are seeking feedback into both the positive and negative experiences people have had with CMIP6, as well as suggestions to improve the structure and delivery of future phases of CMIP. Early career researchers (ECRs) regularly undertake the, often time consuming, task of downloading, processing, and analysing data from CMIP and as such, have a unique, working insight into the successes and flaws of the previous CMIP phases.

This Townhall will be an opportunity for ECRs to meet and network with those on the CMIP7 organisational and design teams and provide feedback on CMIP6, from its design and distribution, to its access and outputs. This Townhall is designed to be an informal and comfortable setting in which ECRs can influence future phases of CMIP in order for its design to be as useful and accessible as possible for those using it on a regular basis. The discussion and outputs of this session will feed directly into the CMIP7 planning and experimental design process.

The primary goal of the World Climate Research Programme’s (WCRP) Coupled Model Intercomparison Project (CMIP) is to better understand past, present, and future climate changes arising from natural, unforced variability or in response to changes in forcing in a multi-model context. Successive generations of CMIP have seen the project grow in scope, with increasing process-specific Model Intercomparison Projects (MIPs) developed to address new and focused scientific questions, while continuing to play a critical role in the IPCC Assessment Reports. The latest phase, CMIP6, was the biggest yet with 131 participating models from 48 institutions, representing 26 countries across the globe and nearly 25 PB of CMIP6 data available across the 30 plus Earth System Grid Federation data nodes.

Under the guidance and direction of the Working Group on Coupled Modelling (WGCM), all CMIP activities are overseen by a coordinated pair of subcommittees: the CMIP Panel and the WGCM Infrastructure Panel (WIP). The WGCM, CMIP Panel and WIP are currently working hard in preparation for the next phases of CMIP, in particular CMIP7. In 2022 the results of the CMIP Community Survey provided in-depth, insightful, and honest feedback that will help support the development of future phases of CMIP. Based on these outcomes the CMIP Panel has sought to identify ways to increase the project’s scientific and societal relevance, improve accessibility, widen participation and reduce its own carbon footprint within the limits of available financial and human resources. This can only be achieved if a broad and diverse community, bridging traditional divides, is involved in the planning, definition, and co-creation of future CMIP phases. Therefore, the CMIP panel and WIP have established a number of CMIP7 Task Teams to support the design, scope, and definition of the next phase of CMIP and evolution of CMIP infrastructure and future operationalisation.

This Townhall will be an opportunity for representatives from the CMIP Panel, WIP and the CMIP7 Task Team leads to give an update on their activities, highlight engagement opportunities and seek feedback from the EGU23 attendee community representing both CMIP data producers and users from the increasingly wide and diverse range of CMIP downstream users. The discussion and outputs of this session will feed directly into the CMIP7 task teams’ ongoing work and the wider CMIP7 planning and experimental design process.

Acquisition and analysis of geochemical data are the fundamental and first step for research in the Earth, environmental, and planetary sciences. Geochemical data are key for understanding past, present, and future processes in natural systems, from the interior of the Earth to its surface environments on land, in the oceans, and in the air, to the entire solar system. However, accessibility and preservation of geochemical data has been sporadic and fragmented. Whilst thematic databases, such as EarthChem or GEOROC, have enabled new ways of mining and statistically analysing large volumes of geochemical data, leading to new discoveries and a demonstrable impact on science, their maintenance is time-consuming, expensive, and not scalable. As more geochemical database systems are emerging at national, programmatic, and subdomain levels in response to Open Science policies and science demands, the need for global standards and best practices for geochemical data is increasingly urgent so that we can better share and link all data resources in a global network.

The OneGeochemistry initiative is an international collaboration between organisations that support geochemistry capability and data production. The initiative focuses on coordinating and consolidating global efforts in geochemical data standardisation in order to create a sustainable data infrastructure that guarantees persistent, machine readable access to the global wealth of FAIR geochemical data. OneGeochemistry has formed a Working Group as part of the International Science Council’s Committee on Data (CODATA) and invites the wider community to engage in the creation and publication of standard geochemical data formats and data gathering-creation-storage workflows.

During this Town Hall, the OneGeochemistry initiative will give an update on activities and progress and invite feedback and suggestions from all disciplines. We invite you to join a discussion on how the community can best help and participate in the creation of geochemical data standards. Our goal is to broaden community awareness of and participation in the initiative, and to further learn from successful initiatives in other disciplines.

Enabling and accelerating the goals of clean, secure, and affordable energy in the ongoing transition toward a zero-carbon global energy sector requires massive mobilization of resources to lower greenhouse gas emissions and increase resource efficiency of energy and material systems. Ordinary citizens are coming together through collective initiatives to confront these challenges and play an active role in the low carbon transition. Throughout Europe, over 2 million people are members in over 10,500 citizen-led energy initiatives. Together, they have created nearly 23,000 projects in different aspects of the energy transition and are jump-starting Europe's renewable energy growth. However, these contributions are often overlooked, and statistical accounting is absent, despite their impact on increased energy self-sufficiency, local sustainable development, greater citizen engagement, diversification of activities, ramping up of renewable energies, social innovation, and acceptance of transition measures.

This Townhall Meeting features a screening of the 20-minute animated film "Power To & By the People" which presents results from the EU Horizon 2020 COMETS project (Collective Action Models for the Energy Transition and Social Innovation). The film draws on our groundbreaking dataset — the first systematic data collection to capture the nature and scope of collective citizen-led action in the energy transition for each country in Europe. The data compiled can be used to support the construction of likely trajectories for citizen engagement and help with monitoring, goal and policy setting, and impact evaluation of these initiatives, which is increasingly needed to support evidence-based policy action in this field.

Synopsis: The film presents strong evidence for the historical, emerging, and actual importance of citizen-led collective action to the European energy transition. The documentary begins with background on energy services and cooperatives, then highlights 10 solutions by citizen action initiatives across Europe addressing various current issues of energy security, sustainability, and the affordable provision of energy services. Lastly, a "Facts & Figures" segment quantifies the aggregate contributions of citizen-led energy initiatives and provides cross-country insights into how collective action shapes the sustainable energy future.

Agenda:
• Welcome
• COMETS project overview, Prof. Dr. Valeria Jana Schwanitz
• FAIRification of the database, Prof. Dr. August Wierling
• Screening of the film "Power To & By the People"
• Q&A / discussion

In preparation of a new global SWx coordination and collaboration effort between COSPAR, WMO, and ISES, upon
Formal request by the UN-COPUOS, we have noted that - while the international space agencies have natural fora to
discuss funding and collaborations regarding any space-based assets - there is nothing similar for the many ground-based
efforts and networks needed for SWx research and predictions.

These networks are mostly created, coordinated and maintained in a quite ad-hoc manner. Typical successful examples are
SuperMAG and SuperDARN, which are global, but often based on multiple bi- or multi-lateral partnerships in more regional
approaches like e.g. the IMAGE magnetometer network in Europe, and individual radar pairs for SuperDARN.

However, already in the case of ionosondes or ground based TEC receivers it does not look that good anymore, and even
the two best examples above are often maintained on a shoestring and instruments come and go on the basis of national
or even individual institutional efforts.

This Townhall Meeting (on behalf of COSPAR and the international SWx community in WMO and ISES) should try to exchange
and discuss ideas from members of the involved communities to identify and formulate future needs and opportunities,
also, about how to share best practices in coordination, maintenance, data sharing and in particular a more sustainable funding.
The timing is excellent to sound the community now and report any findings then further to the COSPAR WMO ISES round table
Discussion in autumn of 2923 and the ESWW in Toulouse.
