Frequently asked questions about Charleston's Climate Shift Index score
How fast is Charleston's climate changing compared to other capitals?
Charleston ranks 152 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 Charleston?
The fastest-shifting variable in Charleston is frost days, at -0.9 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 Charleston warming per decade?
Charleston is warming at +0.28°C/decade across 1976 to 2025. Over thirty years that works out at roughly 0.8°C. The trend accounts for 28% of the variation between years; the rest is ordinary year-to-year swing.
Is Charleston getting more extreme heat days?
Days above 30°C are increasing by +2.9 days/decade in Charleston. On this trend that is roughly 9 days gained or lost every thirty years.
Is Charleston losing its winter?
Frost days are declining by -0.9 days/decade in Charleston. 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 Charleston'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. Charleston scores 45.4. 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.
