Munich Re’s
Climate Change Edition

Climate Change Edition is a comprehensive modular SaaS solution that supports organisations in managing their assets and properties with regards to risks emerging from current natural hazards as well as from the expected impact of climate change.

Integrated into your digital workflows, Climate Change Edition drives your spatial exploration, visualisation and evaluation. Our filter options empower you by giving you deeper insights into evaluating risks and opportunities for your portfolio across the globe.

Coverage ranges from a single asset to multiple assets within a portfolio located in areas prone to the effects of future climate change, such as areas of extreme temperatures, extreme rainfall, drought, tropical cyclones, fire weather, floods, sea-level rise, etc.

Annual anthropogenic CO₂ emissions (GtCO₂/yr)

RCP 8.5: 
Most severe scenario leading to a warming at the end of the 21st century of probably more than 4°C relative to the pre-industrial period (1850-1900)

RCP 4.5: 
Intermediate scenario leading to a warming at the end of the 21st century of more than 2°C relative to the pre-industrial period (1850-1900)

RCP 2.6:
Moderate scenario leading to a warming at the end of the 21st century of probably less than 2°C relative to the pre-industrial period (1850-1900)

The projection years for the three emission scenarios (RCP 8.5, RCP 4.5 and RCP 2.6) are 2030, 2050 and 2100. The projections are a hybrid composite of local high-resolution CORDEX (Coordinated Regional Climate Downscaling Experiment, ~25-55 km horizontal resolution) models and global CMIP5 (Coupled Model Intercomparison Project Phase 5) models.

Data for the reference period is based on well-established current Nathan model data (for Tropical Cyclone, River Flood) and on ERA5 ECMWF atmospheric reanalysis data (for Heat Stress, Precipitation Stress, Fire Weather Stress). The reference period for the climatological parameters is 1986-2005, and 20-year periods are used for the projections for more robust trend estimates.

The scores also contain present-day values, allowing the user to compare two points in time and thus evaluate the changes in different climate-related scenarios.

Risk scores are a powerful tool to help you assess real risk situations, by providing a measure of damage potential for standard industrial businesses.

Climate risk scores

Climate risk scores express the severity of physical damage being caused by natural hazards in future climate scenarios (based on NATHAN risk scores)

The climate overall risk score includes storm, flood and wildfire risk scores with different weightings in combination of the AAL for standard industrial business. The various hazards that have been taken into account include:

• Tropical cyclone
• Extratropical storm
• Hail
• Tornado
• Lightning risk
• River flood
• Flash flood
• Storm surge
• Wildfire risk

The climate storm risk score includes the tropical cyclone, extratropical storm, hail, tornado and lightning risk.

The climate flood risk score includes the river flood, flash flood and storm surge risk.

Risk scores of future scenarios include a combination of current and projected hazard zones (where available, i.e. tropical cyclone and river flood).

Natural Hazards Defended scores*

Natural Hazards Defended scores take into account flood defenses, licensed by JBA. They are calculated for the hazards of river flood and storm surge. Due to a conservative threshold, differences between defended and undefended scores affect only the Netherlands and Belgium.
