Our Use Cases

The COMPASS use cases provide a real-world testbed and insights in the feasibility of attributing compound extremes and their impacts to climate change.
COMPASS developed a harmonised, yet flexible methodological framework that furnishes event-specific steps for the attribution of climate change as a driver of impacts in complex extremes. This framework has been validated and applied to a set of diverse use cases, that cover compound events, sequences of events and cascading events.

Our selected use cases cover complex extremes for various hazard types and impact contexts:

  • France 2010: compound flooding and storm during cyclone Xynthia in 2010
  • United Kingdom 2013: cluster of winter storms in 2013-2014
  • United Kingdom 2022: drought combined with a heatwave in 2022
  • Mozambique 2019: compound flooding due to tropical cyclones Idai and Kenneth in 2019
  • Mozambique 2023: compound flooding due to tropical cyclone Freddy in 2023
  • Honduras 2020 : sequential tropical cyclones Eta and Iota in 2020
  • Poland 2026: single-country use case, not connected to a particular event, demonstrating an operational system for climate change impact on Polish agriculture
  • USA 1996-2024: 104 hurricanes and sea level rise from 1996-2024
  • South Africa, Durban 2022: heavy rainfall, flooding and  landslides in 2022
  • Greece, Crete island 1980-2022: impacts of drought on water availability and demand from 1980-2022
