A global suite of climate change flood risk intelligence spanning near-term to long-term futures, across multiple climate scenarios, delivered in formats that work for you.
Climate change flood maps
JBA’s Global Climate Change Flood Maps provide a continuous, map‑based view of how river, surface water and coastal flood hazards may change under different future climates.
These maps are designed for exploration and visual understanding. They are fully queryable, allowing you to define your own areas and explore how flood risk patterns may shift compared to today.
Because the data is continuous across the landscape, the maps support flexible, exploratory analysis making it easy to identify emerging risk hotspots.
The development of these flood maps builds on our trusted global flood maps for the present day. We combine global climate model projections with sea level rise data from the IPCC’s 6th Assessment Report to understand how both inland and coastal flooding could change in the future. These climate signals are then translated into detailed maps of future flood extents and depths. The result is a consistent, global view of how river, surface water and coastal flood hazards may shift under different levels of warming, helping organisations plan for a changing climate.
Climate change data
For analysis at property or asset level, JBA’s climate change flood data provides fast, location‑specific insights that are easy to access and integrate. Delivered via API as well as in standard data formats, the data enables rapid screening and repeatable analysis at known locations.
The suite includes a range of hazard metrics and risk indicators designed for speed and operational use. The data feeds directly into underwriting, portfolio analysis, regulatory reporting and resilience planning, allowing organisations to quickly understand how flood risk may change across individual assets or entire location level portfolios under different future climate scenarios.
Like our maps, the data is informed by internationally recognised climate projections and provides a consistent view of flood risk under multiple future climate scenarios. By comparing future projections with baseline conditions, the data enables organisations to quickly identify where flood risk may increase or lessen, supporting informed long‑term planning and decision‑making.
Climate change flood models
JBA’s climate change flood models provide probabilistic insights into flood risk for every country, for both present and future climate conditions. Built on internationally recognised climate projections and JBA’s high-resolution flood maps and event sets, the models quantify potential financial losses under intermediate and high warming scenarios, helping organisations to understand how risk may evolve over time. With extensive customisation options, you can explore and tailor model assumptions to develop your own evidence-based view of future flood risk, supporting proactive portfolio management and long-term resilience planning.
How to access JBA’s climate change information
• JBA flood maps are available in GeoTiff format. Web-based access via JBA Vision coming soon.
• JBA flood data is available via API, supporting automation, underwriting workflows and portfolio analysis tools.
• Our catastrophe models are available through established industry platforms, including Moody’s, Verisk Model Exchange, Impact Forecasting Elements and Oasis.
• JBA maps, data and models are also available through our network of service‑enabling partners, ensuring broad compatibility with existing platforms and workflows.
JBA also offers expert consultancy services, providing tailored analysis and interpretation of flood information to support specific business, regulatory or planning needs.
The science behind the climate change data
In creating all our climate change products, JBA applies global climate model-derived change factors, rather than simply scaling present-day flood products. We create new datasets for each future climate.
This approach alters flood risk in line with projected climate signals, enabling structured exploration of how it may evolve under different warming pathways.
Another feature of our approach is the use of climate storylines rather than simple multi-model means. This helps retain physically plausible spatial patterns and supports structured exploration of uncertainty across different future climates.
