Scientinel have today published the brand new Sea Levels App for iOS, making a global accelerated ice sheet melt scenario available to the public for the first time. The Sea Levels App offers a clear, visual way to explore sea level changes around the world.
The app focusses on how rising seas could affect local communities, landmarks, and coastlines under an extreme sea-level rise scenario, first used to plan the construction of the Thames Barrier in London, UK.
Using publicly available elevation data, our app provides a simple interface so everyone – from students to planners – can better understand coastal inundation risks. This knowledge can help communities prepare, adapt, and make informed decisions about the future.
While the app is not meant to replace formal flood defence studies, it’s an easy‐to‐use educational tool to see the big picture of potential climate change impacts on sea levels.
We have computed the worst-case sea level rise projections (adapted from the H++ scenario) for the entire planet. This scenario represents an upper‐range estimate of possible sea-level rise if the Greenland and West Antartica ice sheets melt more quickly than expected and greenhouse gas emissions continue to rise and remain high. Please note that our scenario does not include melting from the East Antarctica ice sheet.
Our trusted global scenario helps highlight worst‐case sea level projections. Originally used to plan the Thames Barrier in London, protecting the city from catastrophic flooding, it shows what could happen if ice sheet melting accelerates. It encourages proactive adaptation, such as building better flood defences and planning new coastal infrastructure.
Scientists continually update sea level rise forecasts as new data emerges. Although there’s some uncertainty in climate modelling, it’s widely agreed that coastal areas worldwide face increasing flood threats from rising seas, storm surges, and land subsidence. Our goal is to give the public a simplified view of these potential changes and encourage community adaptation.
The Sea Levels App is currently available only on iOS for iPhone and iPad via the Apple App Store.
