Calculates climate change analysis as a post-analysis action using the specified analysis result as a reference analysis.
This operation supports analysis based on a variety of RCP (Representative Concentration Pathway) scenarios and SSP (Shared Socioeconomic Pathways) scenarios that project the impact of greenhouse gas emissions based on diverse climate policies.
During processing, the Climate Change Model recalculates average annual loss (AAL) and EP metrics for portfolio and treaty levels.
RCP scenarios
RMS Climate Change Models provide a probabilistic view of a range of representative concentration pathways (RCPs). They model the effect of climate change on hurricanes in the North Atlantic and on windstorms and floods in Europe. The Climate Change Models cover the same geographical scope as the RMS reference models for these regions.
This operation supports modeling based on four RCP scenarios.
rcpScenario | Description |
|---|---|
2.6 | A pathway where radiative forcing peaks at approximately 3 W m-2 before 2100 and then declines to 2.6 W m-2. |
4.5 | An intermediate stabilization pathway in which radiative forcing is stabilized at approximately 4.5 W m-2 and 6.0 W m-2 after 2100. |
6.0 | An intermediate stabilization pathways in which radiative forcing is stabilized at approximately 4.5 W m-2 and 6.0 W m-2 after 2100. |
8.5 | A high pathway for which radiative forcing reaches greater than 8.5 W m-2 by 2100 and continues to rise for some amount of time. |
This operation supports RCP climate change analysis for reference analysis modeled using the following models:
| Model | Engine | Supported Versions |
|---|---|---|
| EUFL: Europe Inland Flood | HD | 1.0 and later |
| EUWS: Europe Windstorm | DLM | Any |
| EUWS: Europe Windstorm | HD | 1.0 and later |
| JPWS: Japan Typhoon and Flood | HD | 2.0 and later |
| NAHU: North Atlantic Hurricane | DLM | Any |
| NAWF: North America Wildfire | HD | 1.0 |
| NZFL: New Zealand Inland Flood | HD | 1.0 |
| USFL: US Inland Flood | HD | 1.1 and later |
SSP scenarios
This operation supports four scenarios (1-2.6, 2-4.5, 3-7.0, 5-8.5 ) that combine SSP scenarios (SSP1, SSP2, SSP3, SS5) and RCP scenarios (2.6, 4.5, 7.0, 8.5). Each scenario represents a unique set of socioeconomic and emission trajectories.
sspScenario | SSP Scenario | RCP Equivalent |
|---|---|---|
1-2.6 | SSP1: Sustainability ("Taking the Green Road") | 2.6 |
2-4.5 | SSP2: "Middle of the Road" | 4.5 |
3-7.0 | SSP3: Regional Rivalry ("A Rocky Road") | 7.0 |
5-8.5 | SSP5: Fossil-fueled Development ("Taking the Highway") | 8.5 |
This operation supports SSP climate change analysis for reference analysis based on the following models:
| Model | Engine | Supported Versions |
|---|---|---|
| AUBF: Australia Bushfire | HD | 1.0 |
| NAWF: North America Wildfire | HD | 2.0 |
Climate change model support
