Climate change will make us feel like we’re headed south

Study maps how cities will be affected by warming by comparing to other locations

WASHINGTON — The climate in New York City in 60 years could feel like Arkansas now. Chicago could seem like Kansas City and San Francisco could get a Southern California climate if global warming pollution continues at the current pace, a new study finds.

In 2080, North Carolina’s capital, Raleigh, could feel more like Florida’s capital, Tallahasse­e, while the nation’s capital will have a climate more akin to just north of the Mississipp­i Delta, if the globe stays on its current carbon pollution trend. Miami might as well be southern Mexico and the beautiful mornings in future Des Moines, Iowa, could feel like they are straight out of Oklahoma.

That’s according to a study Tuesday in the journal Nature

Communicat­ions that tries to explain the effects of climate change better.

“The children alive today, like my daughter who is 12 — they’re going to see a dramatic transforma­tion of climate. It’s already underway,” said study lead author Matt Fitzpatric­k. He’s an ecology professor at the University of Maryland’s Center for Environmen­tal Sciences in Frostburg, Md., which won’t quite measure up to its name when it has a climate more like present-day southern Kentucky.

But if the world cuts back on its carbon dioxide emissions, peaking around 2040, then New York’s climate can stay closer to home, feeling more like central Maryland, while Chicago’s climate could be somewhat like Dayton, Ohio’s.

Fitzpatric­k looked at 12 variables for 540 U.S. and Canadian cities under two climate change scenarios to find out what the future might feel like in a way a regular person might understand. He averaged the climate results from 27 different computer models then found the city that most resembles that futuristic scenario.

“Wow,” said Northern Illinois University climate scientist Victor Gensini, who wasn’t part of the study. “The science here isn’t new but a great way to bring impacts to the local scale user.”

The 540 cities on average move 528 miles to the south climate-wise, if carbon emissions keep soaring. If the world cuts back, the cities move on average 319 miles.

The city that moves the most is Wasilla, Alaska, which if emissions aren’t cut back could feel like eastern Wisconsin, 11 degrees warmer in the summer. It’s a change of about 2,720 miles.

“Visualizat­ions that tap into our own lived experience­s make a lot of sense,” said Oregon State University climate scientist Kathie Dello, who wasn’t part of the study and doesn’t like what it shows for her region. “Telling people in historical­ly mild Portland that the climate in the late 21st century will be more like the hot Central Valley of California is jarring.”
