Climate Migration Calculator
Climate Risk Scores by City (Composite 0-100)
Higher scores indicate greater overall climate risk. Based on flood, wildfire, hurricane, heat, and drought exposure.
| City | Flood | Wildfire | Hurricane | Heat | Overall Score |
|---|---|---|---|---|---|
| Miami, FL | 95 | 15 | 90 | 85 | 82 |
| Houston, TX | 90 | 10 | 80 | 90 | 76 |
| Phoenix, AZ | 20 | 40 | 5 | 98 | 62 |
| Los Angeles, CA | 25 | 85 | 5 | 70 | 58 |
| Denver, CO | 30 | 50 | 5 | 45 | 35 |
| Minneapolis, MN | 35 | 10 | 5 | 30 | 22 |
| Duluth, MN | 20 | 15 | 5 | 10 | 14 |

How to Convert Oven Recipes to Air Fryer
This calculator compares climate risk scores across U.S. cities based on five major hazards and provides cost-of-living context to help evaluate potential climate migration decisions.
The basic rule:
- Risk scores (0-100) are composite ratings based on historical event frequency, projected future exposure, and infrastructure vulnerability for each hazard
- Hazards scored: flooding, wildfire, hurricane/tropical storm, extreme heat, and drought
- Cost of living index uses national average as 100, covering housing, food, utilities, transportation, and healthcare
- Moving cost estimates include professional movers, travel, temporary housing, and adjustment costs based on distance
Climate risk is one factor in relocation decisions. Job availability, family ties, community, healthcare access, and personal preference all matter. Risk scores are based on current data and projections — actual conditions may differ.
When Would You Use This Calculator?

- When you want to verify a quote or estimate you've received from a professional
- When teaching or learning about the concepts behind these calculations
Frequently Asked Questions
Which U.S. cities have the lowest climate risk?
Cities consistently rated as lower climate risk include: Duluth, MN; Burlington, VT; Portland, ME; Buffalo, NY; Minneapolis, MN; Madison, WI; and Asheville, NC. These cities have lower exposure to hurricanes, extreme heat, and drought, though they face their own challenges like harsh winters and some flood risk.
Which cities are most at risk from climate change?
Higher-risk cities include Miami and Southeast Florida (sea level rise, hurricanes), Phoenix and Las Vegas (extreme heat, drought), New Orleans (flooding, hurricanes), Houston (flooding, heat), and parts of coastal California (wildfire, drought). Risk levels are increasing in these areas as climate impacts intensify.
How is climate risk score calculated?
Our composite score weighs five hazards: flooding (historical flood events, sea level rise projections), wildfire (burn probability, WUI proximity), hurricanes (historical storm frequency and intensity), extreme heat (days above 100F, urban heat island effect), and drought (Palmer Drought Index, water supply projections). Each is scored 0-100 and weighted by severity.
Will insurance costs keep rising in high-risk areas?
Yes, significantly. Insurance premiums in high-risk areas are projected to increase 50-100% over the next decade. Some insurers are already withdrawing from high-risk markets (e.g., State Farm leaving California homeowners). FEMA's Risk Rating 2.0 is also increasing flood insurance costs to reflect actual risk more accurately.
Is climate migration already happening?
Yes. Research shows net migration away from areas with repeated natural disasters (e.g., coastal Louisiana, fire-prone California regions). Cities like Boise, Duluth, and Buffalo have seen increased interest from climate-conscious movers. However, most climate migration remains domestic and gradual rather than sudden.
How much does it cost to relocate to a new city?
Average interstate moving costs range from $3,000-8,000 for a 3-bedroom home. Add temporary housing ($2,000-5,000), travel costs, security deposits, and adjustment costs. Total relocation typically runs $10,000-25,000 depending on distance and household size. Some employers offer relocation assistance.
