In one generation, the climate experienced in many North American cities is projected to change to that of locations hundreds of miles away—or to a new climate unlike any found in North America today.

A new study and interactive web application aim to help the public understand how climate change will impact the lives of people who live in urban areas of the United States and Canada. These new climate analyses match the expected future climate in each city with the current climate of another location, providing a relatable picture of what is likely in store.

Emissions - Dweller - Miles - South - Climate

"Under current high emissions the average urban dweller is going to have to drive more than 500 miles to the south to find a climate like that expected in their home city by 2080," said study author Matt Fitzpatrick of the University of Maryland Center for Environmental Science. "Not only is climate changing, but climates that don't presently exist in North America will be prevalent in a lot of urban areas."

The study found that by the 2080s, even if limits are placed on emissions, the climate of North American urban areas will feel substantially different, and in many cases completely unlike contemporary climates found anywhere in the western hemisphere north of the equator.

Emissions - Century - Climate - Areas - Average

If emissions continue unabated throughout the 21st century, the climate of North American urban areas will become, on average, most like the contemporary climate of locations about 500 miles away and mainly to the south. In the eastern U.S., nearly all urban areas, including Boston, New York, and Philadelphia, will become most similar to contemporary climates to the south and southwest. Climates of most urban areas in the central and western U.S. will become most similar to contemporary climates found to the south or southeast.
