If generally accepted predictions of global warming come to pass, Arizona's transportation system will have to adapt due to stronger dust storms, snowfall, flooding, forest fires and other factors, experts say.
"If we have increasing high temperatures at airports like Sky Harbor, aircraft can't get enough lift to take off and they only can be used at certain temperatures," said Gregg Garfin, assistant professor at the University of Arizona's School of Natural Resources and the Environment.
Garfin said that the Valley's intense heat already shortens the life of roads. As another example, he noted that smoke from forest fires, which are expected to be more frequent as temperatures increase, can make it difficult for drivers to see.
The Arizona Department of Transportation recently launched a study, funded by a $125,000 grant from the Federal Highway Administration, of how extreme weather fueled by climate change could affect travel on Interstate 10, I-17 and I-19.
