Quick-Start Guide

Follow this step-by-step guide for a basic overview of the map functionality. The map can be accessed here.

Selecting Climate Scenario Parameters

First, we need to select a combination of parameters for the desired climate scenario.

Select a Climate Risk Measure: Start by choosing a climate metric of interest from the drop-down menu. These are climate hazards curated by our team that may pose potential risks to infrastructure. Choose a Scenario: Select one of the available climate scenarios (e.g., SSP126 for low emissions, SSP585 for high emissions). Scenarios help you understand potential futures under different climate action pathways. Select a Timescale: Use the timeline slider to choose the time period you are interested in, ranging from the 2020s to the 2100s for all months. This lets you see how climate risks evolve over time for particular months of the year. The example on the right illustrates a scenario where the selected measure is "% Area Covered by Burnt Vegetation"—used as a proxy for wildfire risk—under a moderate emissions projection for August in the 2060s.

Selecting Infrastructure Overlays

Second, we need to select the specific types of infrastructure we are interested in visualizing.

Select Infrastructure Overlays: On the right-hand side, you'll see a layers icon. Hover over it to reveal the available infrastructure overlays. In this example, the available infrastructure includes specific types of power grid data, which provides insight into its exposure under the selected climate scenario.

Download Data

From here, you can explore the map and your particular areas of interest visually to get a sense of asset exposure. You may wish to download the data to do an offline analysis, which can be done easily.

Draw a bounding box: On the right-hand side below the layers icon, there is a small black box icon. Clicking this will allow you to draw a box (or multiple boxes) over your area of interest. Click Download Data: On the control panel, click the Download Data button to download a CSV file. Data will be downloaded based on the layers and control panel values you have selected.

Methodology

This section outlines the methodology behind the Climate Risk Mapping Platform, divided into three key categories: Physical Assets, Climate Science, and Risk Metrics.

Physical Assets

Physical asset data forms a critical component of climate risk assessment. These assets—such as structures, facilities, and infrastructure—represent the elements that, if affected by climate events, could have significant impacts on communities and economies. Our objective is to develop a standardized physical asset data model that can be represented within a database. This model will contain a comprehensive set of asset properties, enabling downstream integration with climate data for the calculation of asset-specific risk metrics.

Currently, we source this data from OpenStreetMap (OSM). The raw data undergoes processing to extract the relevant infrastructure types and prepare them for use in the climate risk model. We cross-reference* the infrastructure data with other external sources to ensure both accuracy and completeness, ultimately creating a reliable dataset for physical asset analysis.

Climate Science

A major challenge in assessing climate-related financial risk is bridging the gap between the resolution of climate hazard data and that of physical asset data. Current CMIP6 climate models typically offer climate projections at a resolution of 100 km or coarser, while physical asset data—such as power infrastructure data from OpenStreetMap—often has a resolution of 250 meters or finer. To perform meaningful risk assessments, climate hazard data must be downscaled to best compliment the resolution physical asset data, while maintaining scientific rigor.

In our analysis of climate risks related to wildfires in the Pacific Northwest, we propose two approaches: utilizing an established physics-based model and developing an AI-driven model.

Physics-Based Downscaling Approach

The physics-based approach involves creating a wildfire weather index using ECMWF's GEFF wildfire model.

• Input Data:
  • Downscaled CMIP6 data provided by NASA (NEX-GDDP-CMIP6, 25 km horizontal resolution, available on AWS).
• Key Benefits:
  • High credibility: ECMWF is a globally recognized authority in climate data, and using an established model like GEFF would lend credibility to our work.
  • More ensemble members: NEX-GDDP-CMIP6 includes a wide range of climate models and future climate scenarios, allowing for robust scenario analysis in financial risk assessments.
  • High efficiency: The model is diagnostic and computationally efficient, making it suitable for large-scale analyses.

• Current Progress
  • We are currently reaching out to ECMWF for guidance on setting up and running the model.

AI-Based Wildfire Forecast Model

This AI model aims to address the forecast gap for seasonal and sub-seasonal wildfire prediction, especially in high-risk areas like Washington and Oregon. By filling the existing forecasting gap, this model would provide valuable insights for proactive wildfire mitigation and financial risk planning.

• Input data
  • Historical wildfire records from Washington and Oregon
  • Surface weather conditions (e.g., temperature, humidity, wind speed)
  • Fuel-related factors (soil moisture, vegetation greenness, etc..)

• Key Benefits
  • Machine learning can uncover complex, non-linear patterns in wildfire behavior that physics-based models might miss. It also produces wildfire forecast much faster than physics-based models.

• Current Progress
  • Plans to partner with the group led by Pierre Gentine at Columbia University for data sourcing, model development, and validation.

While immediate focus is on wildfires, this downscaling approach can be expanded to other climate hazards (e.g., flooding, heatwaves). By continuously improving downscaling techniques and leveraging AI, we aim to build a comprehensive platform for high-resolution climate hazard data that can be used for financial risk analysis across multiple sectors

Risk Metrics

Once the physical asset and climate hazard data are accessible, we can begin using these together to calculate measures of physical climate risk. These start with exposure and vulnerability metrics, which are then ultimately use to derive the financial risk and impacts of climate.

Exposure

First, we will want to compute an exposure of our physical assets to the climate hazard. This involves geospatial intersections of the climate data with the physical asset location data. This sets the stage and provides what level of exposure a given physical asset has to the hazard.

A prototype of this calculation is computed for power grid infrastructure and a CMIP6 variable for the Climate Risk Map.

Github: Prototype Exposure

Vulnerability

The vulnerability measures the actual damage caused by the exposure of the asset to the hazard. This is a future goal of the Climate Risk Map to compute this.

Data Dictionary

The Climate Risk Map generally provides data at the asset level, along with associated properties and climate risk measures (exposure, vulnerability, etc...). Below are the initial fields available for download (subject to change).

osm_id: Integer – Unique identifier for each OpenStreetMap (OSM) object. This ID is crucial for referencing and linking OSM features with external datasets or within the OSM database.

osm_type: String – Indicates the category of the OSM feature. For power-related features, this type is typically “power,” representing different aspects of power infrastructure such as power lines or substations.

tags: JSON – A JSON-like field that stores metadata about the OSM feature. Tags may include identifiers, names, and other relevant information (e.g., {'ref': 'GCOU-CHJO-3', 'name': 'Grand Coulee-Chief Joseph No 3'}), providing important context about the feature.

geometry_wkt: String – The geometry of the OSM feature in Well-Known Text (WKT) format, which describes the shape and position of the feature using coordinates. For power lines, this typically defines a line geometry.

longitude: Float – Represents the east-west geographic centroid coordinate of the OSM feature, specifying its position on the Earth's surface.

latitude: Float – Represents the north-south geographic centroid coordinate of the OSM feature, specifying its position on the Earth's surface.

osm_subtype: String – A more specific type of OSM feature within the power category. For example, “line” could represent a power transmission line.

county_name: String – The name of the county where the OSM feature is located, helping to contextualize the feature’s geographic location at a local level.

city_name: String (optional) – The name of the city where the OSM feature is located, if applicable. This field may sometimes be empty if the feature is not within a defined city boundary.

ssp: Integer – Likely refers to the Shared Socioeconomic Pathway (SSP) scenario used in climate models. For example, an SSP value of 370 may refer to the SSP3-7.0 scenario, which models future socio-economic development and its impact on climate change.

month: Integer – Represents the month of the year in the dataset, where 1 stands for January, 2 for February, and so on. This is important for analyzing seasonal climate data.

decade: Integer – Represents the decade of the data (e.g., 2060), helping to differentiate climate data projected for different time periods.

climate_variable: String – Specifies the particular climate-related metric of interest (e.g., “burntFractionAll”). This indicates the environmental factor being assessed, such as temperature, precipitation, or other relevant variables.

climate_exposure: Float – Provides a numeric value indicating the degree of exposure the OSM feature has to the specified climate variable. For example, a value of 1.445 for "burntFractionAll" would represent 1.445%.
