By now it’s common knowledge that as greenhouse gases continue to accumulate in our atmosphere, intensely high temperatures are likely to occur more frequently.

But Climate Central, a climate research and news organization, has developed a way for residents of the continental U.S. to see exactly how much their communities will be affected. The interactive tool allows users to type in the name of their city or town and view the average number of days that will exceed specific temperature thresholds in 2050, 2075 and 2100.

The analysis includes data for nearly 30,000 cities and towns of various sizes from across the continental U.S. Each graph provides two possible outcomes: one in which greenhouse gas emissions continue as usual and one in which they are moderately curtailed.

Researchers based their projections on aggregated data from 21 global climate models.

At present, Des Moines experiences an average of zero days per year when the actual temperature is above 100 degrees Fahrenheit. According to this study, the city will likely see 15 days annually that exceed the temperature threshold in 2050 and up to 30 per year in 2100.

This year is on track to be the hottest year ever, followed by 2016, 2015, and 2014, respectively.
