From the growing use of weather-sensitive renewables and changes in demand patterns to the increasing exposure of key infrastructure assets, the need for meteorological information to manage weather and climate risk has never been greater. Nowhere is this more obvious than in being able to accurately characterise ‘extreme weather’ events. Through hands-on ‘case study’ activities, this workshop will discuss some of the scientific challenges associated with producing high-quality actionable climate information for energy system operations and planning. Working with others from both the energy and climate communities, participants will think of new ways to address these challenges using research emerging from the meteorological community, asking the question: how can meteorological science better support the transition to a low-carbon energy future?Please click here for more informationThrough small team activities, we will explore ideas for using hybrid approaches in weather forecasting and climate models; combining traditional physics-based approaches with machine learning. After a brief introduction to technical details, the focus will be on new ideas for using observations and model data to better represent the physical processes and interactions in the land-atmosphere-ocean system.

Focusing on developing interdisciplinary approaches to improve scientific approaches, impact assessments and risk management strategies, keynote presentations and structured discussions will explore recent advances in identifying, modelling, and predicting compound events and their amplified impacts on critical infrastructure, ecosystems, and communities. The workshop will draw on case studies to highlight real-world examples of high-impact cascading risks, including disruptions to energy, transport and supply chains.The workshop is seeking interdisciplinary participants including climate scientists, engineers, policymakers, and risk analysts, aiming to fill knowledge gaps and bridge research and application.The workshop will help identify recent progress and priority research areas in support of the ongoing UK Fourth Climate Change Risk Assessment independent assessment (CCRA4). The workshop will be supported by two Horizon Europe projects MEDiate: Multi-hazard and risk-informed system for enhanced local and regional disaster risk management and COMPASS: Compound extremes attribution of climate change: towards an operational service.The full workshop agenda is available to download.This workshop is supported by:The Met Office' purpose is to 'help you to make better decisions to stay safe and thrive’. To fulfil this, we must understand how people make decisions. This requires transdisciplinary working across the physical and social sciences, including psychology and behavioural science.One important aspect of decision-making, is the potential for cognitive biases, this is particularly relevant for how people understand and respond to weather warnings.In this workshop we will explore decision theory, and consider how cognitive biases can impact how people respond to weather and climate information, including suggestions for ways in which we might mitigate these challenges. Please could all delegates bring their mobile phones to this workshop for use in the session.For more information on the session, please click here.Air pollution is a major public health risk, contributing to respiratory and cardiovascular diseases, low birth weight, and cognitive decline. In particular, fine particulate matter (PM2.5) is of particular concern because it can penetrate deep into the lungs and bloodstream as well as having a wide range of sources which change in their relative importance through the year. The smallest particles (PM0.1) are small enough to cross the blood/brain barrier, which results in neurological decline caused by the toxic nature of this material. Furthermore, the health burdens are often unevenly distributed, disproportionately affecting disadvantaged communities creating an environmental justice element in the quality of the air we breathe. The recent report from the Royal College of Physicians has estimated that around 30,000 deaths per year in the UK are thought to be attributed to air pollution, with an economic cost of £27 billion in the UK due to healthcare costs, productivity losses and reduced quality of life. When wider impacts such as dementia are accounted for, the economic cost may be as high as £50bn every year, this represents over 2% of the UK GDP. While tailpipe emissions from transport have decreased, diesel vehicles, especially older models, remain a major source of both PM and also NO₂ whilst the shift to electric vehicles has reduced combustion emissions but raises questions around tyre wear, brake dust, and also upstream energy source emissions. A growing source of PM in the UK is wood burning in stoves and open fires for secondary heating, especially in suburban and rural areas. The size of this particulate material also means that there is potential for significant long range transport which imposes a higher regional background concentration which we have no way to control. This means that the UK is very challenged to meet the WHO guideline levels for PM2.5 which were set in 2021. Given all of this clear evidence of the dangers of exposure to air pollution, many feel that public awareness is still limited, and regulation/enforcement is often weak. Since the pandemic there has been a major shift to include indoor air quality which is a considerably more variable mix of gases and particles. In order to better assess human exposure we need to consider that most people spend a large fraction of their time inside and across a number of very different settings.We will discuss where the data challenges are, particularly with the growth of citizen and community led science and also consider how we best make use of low-cost sensors which are growing rapidly but present their own challenges in terms of data quality and integration. 13.00Lunch and Networking Keynote PlenaryRoom: G.42 14.15Keynote Presentation: Drivers of Humid Heat Extremes across the Global TropicsCathryn Birch (she/her), Professor of Meteorology and Climate, University of Leeds14.45Keynote Presentation: Translating Academic Research for the MediaAyesha Tandon (she/her), Science Correspondent, Carbon Brief15.15Keynote Presentation: Climate Projections of Net-Zero FuturesAndrea Dittus (she/her), NERC Independent Research Fellow, National Centre for Atmospheric Science, University of Reading15.45Refreshments and Networking Break Move into Parallel Oral Sessions FloodsRoom: 1.08/1.07ExtremesRoom: G.42DynamicsRoom: G.37 Chair: Andy RussellChair: Bria GrangeChair: Simon Lee16.25Testing the Predictability of Intense Convective Rainfall in the UK: Results from the 2024 Met Office summer testbedBrian Golding, Fellow in Weather Impacts, Met Office and President, Royal Meteorological Society An Urban Street Canyon Heat Stress Calculation Method for Weather and Climate ModelsJon Shonk (he/him), Senior Scientist, Met Office Europe’s Elevated Mixed Layer: New Insights into the Spanish PlumeDavid M.

As the climate changes, we are seeing more extreme hazards. In certain regions, it may be that the risk is so high that property, or business, becomes uninsurable, or has limited coverage. Recent examples are the withdrawal of some insurance companies from the California Wildfire market, citing too high risk. This is a region that was then heavily impacted in early 2025. For many hazards (e.g. Hurricane’s in Florida) the risk potential is understood, however, owing to the high year-to-year variability and potential changes from climate change, the exact impact in the coming 5-10 years is uncertain. Through utilisation of decadal forecasting products a greater understanding of the risk in the coming years, and what regions may be that are not now, can be made. Information of this type can help insurers understand how to evolve premiums, and understand the impacts facing their portfolios in the near-term. This workshop will explore regions of potential decadal predictability that are currently at high risk, and regions where we expect to see rapid changes in the coming years. Participants from industry will highlight the key usability of this information, with group discussions focussing on areas for research development, pathways to impact, and utilisation of existing data products.Effective and efficient policy requires a robust evidence base to inform the direction of the policy development. However, the process by which policy professionals find and use evidence can be opaque and difficult to penetrate. Even the meanings of "evidence", “policy” and “policy makers” are not clear to many of us or consistently used by different actors. In this workshop we aim to discuss and share our experiences on different ways that weather and climate researchers can, and have, engaged with policy professionals and what they learned from that experience. We’ll go through this process in 3 steps: 1. We’ll start with a short overview of Government(s), Parliament(s) and other policy relevant actors and routes to engagement in the UK.2. Then we’ll hear from some people who have spent significant periods of time working with different policy actors and how that impacted their research and what they learned from the process.3. Finally, we’ll open to floor to questions and discussion about why and how you might want to (or already have) engaged in the policy process and also think about actions you can take to engage the right policy professionals in your research process.Despite the logical and evidence-driven, forthright approach we take to researching and communicating Climate Science, we continue with a system that will ultimately destroy humanity.We are distressed with how clear warning signs are ignored and a global lack of action. As scientists we are emotionally involved, but unsure how to translate this into our roles.In this workshop we seek perspective, using tools such as the Planetary Boundaries, and holistically considering environment, society and a designed economy. Understanding the psychology at play, how systems drive what we do, and in the face of overwhelming issues just what meaningful professional action really looks like.The session is a safe and positive space to interact, to share ideas and concerns, to ask the questions you need to. You will work out your own response, having time to workshop a personal approach and future strategy. 14.30Moving into Final Plenary sessionRoom: G.42 Chair: Liz Bentley 14.35On the Predictive Value of Upper Stratosphere Dynamics for the Winter NAOLizzie Collingwood (she/her), PhD Student, British Antarctic Survey, University of Southampton14.50The Devil’s in the Detail – Medium range forecasts for the publicBen Ayliffe (he/him), Post-processing Scientist, Met Office15.05Counterfactuals2 : Exploring the plausible limits of future extremesNick Leach (he/him), Senior Research Scientist, University of Oxford // Climate X Ltd15.20State of the UK Climate in 2024Mike Kendon, Climate Information Scientist, Met Office15.35Conference Conclusions 15.45Conference Close
