Frequently asked questions about Indianapolis's Climate Shift Index score
How fast is Indianapolis's climate changing compared to other capitals?
Indianapolis ranks 90 of 245 world capitals for how fast its climate is shifting. That places the city in the middle of the ranking. The ranking measures pace of change, not how hot or how pleasant a city is.
What is changing fastest in Indianapolis?
The fastest-shifting variable in Indianapolis is frost days, at -1.9 days/decade. That is the change per decade, fitted as a linear trend across 1976 to 2025, so over 50 years of measured data rather than two isolated years.
How much is Indianapolis warming per decade?
Indianapolis is warming at +0.38°C/decade across 1976 to 2025. Over thirty years that works out at roughly 1.2°C. The trend accounts for 36% of the variation between years; the rest is ordinary year-to-year swing.

Is Indianapolis losing its winter?
Frost days are declining by -1.9 days/decade in Indianapolis. Frost days are often the fastest-shifting variable in this dataset: cold extremes tend to warm faster than hot ones, which bears directly on anything sized for a cold season.
What does Indianapolis's Climate Shift Index score actually mean?
The score folds six variables (temperature, tropical days, frost days, precipitation, sunshine hours and wind speed) into one number, converting each into a percentile against every other ranked capital. Indianapolis scores 57.8. A low score does not mean nothing is changing, only that other capitals are shifting faster, and the score says nothing about how liveable or how warm a city is.
