Study Projects Average Phoenix Metro Temperatures 6-10 F Hotter Than Now By 2100
EDIT
Look for a huge increase in the number of Arizona days with high temperatures that exceed 95 Fahrenheit, the report says. Average daily temperatures in Maricopa, Yuma, Mohave, Pima and Pinal counties by 2100 will be about 6 to 10 degrees higher than today, maps from the report show.
This will likely push Arizonas above-95-degree days from 116 today to as many as 205 by 2099, the report says. Nationally, the average U.S. resident will likely see an average of 46 to 96 days annually over 95, compared with 15 such days between 1981 and 2010, the report says.
Three prominent UA climate researchers Jacobs, Jonathan Overpeck and Gregg Garfin say the projections are in line with those in other reports, including the National Climate Assessment. The results appear to have been generated by a credible team, at least with respect to the climate science, says Overpeck, director of UAs Institute for the Environment. The numbers highlight how Arizona will get hit hard by climate change unless the climate change is slowed significantly.
If you add the reports projected temperature increase by midcentury of about 4 degrees, plus additional nighttime warming from the urban heat-island effect, Tucsons temperatures would match those of Phoenix today, says Garfin, a deputy director for the institute. Go to the end of the century and, now we in Tucson are exceeding current temperatures in Yuma and Phoenix, Garfin says.
