It's a sorry truth that hits you mid-July: Average summer temperatures have been rising since the 1970s. If we continue down this path, according to a new study by Climate Central, in 2100, summers in Boston will feel more like sticky Miami—and summers in Miami will feel like toasty Harlingen, Texas.
Simply type where you live into the chart below and you'll get an instant comparison between the average summer high temperature in your city today and the city your home is more likely to feel like in 86 years. If greenhouse gasses and climate change keep chugging along at the rates they are right now, anyway. It's more of a fun thought experiment than an exact science.
It's surprising to see not only the temperature increase but the comparison city. San Diego (average high 78.17 degrees) will only be as warm as Lexington, Kentucky (84.61). But Fargo (average high 80.24 degrees) will warm by over 12 degrees by 2100, making it feel more like Tyler, Texas (92.08). In fact, most American cities will end up feeling like somewhere in Texas or Florida by 2100.
Type in Las Vegas, however, and there's no American comparison. You'll be shuttled halfway around the world to Riyadh, Saudi Arabia, where the average summer high is a balmy 111 degrees.
This map can't tell the future though. This is only a prediction based only on current trends—if greenhouse gas emissions continue to increase at the rate that they have been increasing since the 1970s. Even though this map shows a very dystopian future, it's one that we can hopefully avoid. [Climate Central]
