Climate risk modeling
Current climate challenges and the role of climate risk modeling
As climate change intensifies worldwide, governments and organizations must brace for severe—and increasingly devastating—risks predicted to disrupt socioeconomic systems across the globe. While historic records of past extreme weather were once reliable predictors of future extreme weather, climate change now changes the game. To meet resilience goals, discover actionable approaches, and make the case for mitigation, organizations should rely on climate risk modeling—a necessity in predicting future climate scenarios.
Climate risk modeling is the process of using the latest climate science and data to project changes in future extreme weather—including heat, droughts, flooding, and storms—and the potential impacts of that weather.
Considering the Biden Administration’s goal of achieving net-zero greenhouse gas (GHG) emissions by 2050, climate action is a top priority for mitigating the severe physical and economic damages that result from climate change. Fewer greenhouse gas (GHG) emissions result in less extreme weather, ultimately reducing the harm caused to people and communities across the globe.
The risks are expansive and powerful, including direct impacts on agriculture and food systems, energy resources and demand, transportation and infrastructure, financial and banking sectors, natural habitats, livability, and displacement.
But across all industries, preparing for and mitigating against future damage requires precise climate risk modeling. Climate risk modeling provides agencies and organizations with the opportunity to make informed cases for forward-looking action, achieve resilience goals, and reveal potential actions.
Climate risk modeling uses large datasets to identify key scenarios and create actionable insights, including:
- Targeting national expenditure and regional program development
- Assessing vulnerability to inform long-term energy infrastructure and resilience planning
- Projecting crop yield, growing-season changes, and adaptation for long-term agricultural planning
- Screening potential investments for risks and opportunities
In addition to mitigation, climate risk models deliver the data necessary to create short- and long-term solution plans that reinforce and enhance industry and consumer confidence.
Climate risk modeling is only as good as the platforms used to crunch the data. Models tell you how the climate and extreme weather are projected to change, but additional analyses are needed to understand what risks or impacts those projections pose to a client. This is important, because it allows a platform such as ClimateSight to apply sectoral expertise to help understand and address climate risks.
Climate risk models and types
Climate risk models take a variety of forms, each synthesizing the complexity of surrounding variable data to provide clear, visual, and actionable data. With proven science-based processes, each model type serves a particular purpose—but all provide organizations with a visualization of scenarios that inform future risk assumptions and resiliency decisions based on industry needs and infrastructure.
Numerical weather model (NWM)
The most familiar weather model, NWMs use weather model data to forecast different types of weather, including precipitation, temperature, barometric pressure, and other meteorological elements. NWMs can be customized to create visual representations depending on specific meteorological needs.
Global climate model (GCM)
GCMs improve long-term understanding and prediction of the major climate system components—atmosphere, land surface, ocean, and climate behavior. They provide a global view of climate but can be customized at a specific regional level with granular detail. GCMs predict the long-term climate behavior that directly leads to disruptions, like the impact of emissions on extreme heat and precipitation.
CAT modeling
Short for catastrophe modeling, this model estimates losses and simulates potential financial catastrophes using computer-assisted calculations. Insurance companies often use CAT models to evaluate and manage devastating risks from natural disasters like hurricanes, earthquakes, floods, and wildfires.
Climate risk model
The climate risk model blends a version of the GCM model and the CAT model to provide a robust view of climate risk scenarios. Importantly, climate risk models also include a financial component to help companies determine future climate risk planning from multiple angles, including socio-economic.
Benefits of climate modeling
Climate modeling allows organizations to translate their resilience goals into actionable plans and programs. Achieving goals starts with capturing the right data in order to visualize a long-term plan. Climate models prepare your agency or company to prepare for “what if” scenarios, with data informed by science. Maintaining infrastructure against catastrophic changes requires long-term planning, and climate risk modeling provides agencies and companies with the data and tools to execute on short- and long-term planning.
Climate modeling also includes adaptation benefits and co-benefits. Adaptation benefits incorporate reversibility and robustness of solutions to support flexible resilience strategies. Co-benefits factor in important features like safety, customer financial benefits, reputational benefits, equity, and infrastructure upgrades—pieces often intertwined. For example, identifying climate risks and addressing them through adaptation can both increase an organization’s operations while also upgrading infrastructure in underserved communities.
When earning stakeholder buy-in, capturing the full range of such benefits can help build mutual support for a resilience strategy.
Physical and transition risks
Climate risk analysis often requires encompassing two broad categories of risk: physical risks and transition risks. Both provide meaningful data for benchmarking and developing climate action strategies.
Acute physical risks result from natural, climatic events like floods or wildfires. While important to measure—and increasing in frequency due to climate change—it’s also necessary to model the trajectory of longer-term physical risks like rising sea temperatures. By factoring in both types of physical risks, the climate risk model can provide a more comprehensive view of future projections.
Transition risks take into account large-scale transformation of systems, policies, and economies directly tied to large-scale decarbonization efforts. Transition risks shine a light on changing behaviors and business models based on such transformations. Transition risks are important to account for across industries, and can provide opportunity for analysis of climate strategy investments.
