Phoenix's average high temperature during the summer is projected to reach more than 114 degrees by the year 2100.
The current average high temperature in Phoenix is just below 104 degrees.
-Claims That Metro Phoenix Is Doomed Because of Climate Change Are Exaggerated
The group Climate Central points out that under current climate-change projections, Phoenix will have the same high temperatures in 2100 as Kuwait City -- one of the hottest cities in the world -- has right now.
The projections are based on those made by the Intergovernmental Panel on Climate Change (IPCC), the organization that, alongside Al Gore, won the Nobel Peace Prize in 2007.
Climate Central used the IPCC predictions -- which generally estimate that summer high temperatures will be seven to 10 degrees higher by 2100 -- to make an interactive map to compare the current temperatures with cities that already experience those temperatures. For example, Sacramento will feel more like Tucson in the summer. Boston will feel like Miami (humidity levels weren't taken into account). And Austin, where the average summer high is currently about 94 degrees, is projected to be more like Gilbert, which has an average summer high of nearly 104 degrees.
Sure, it's only a projection. But we'll note that several sources claim the IPCC is conservative in making such estimates (examples: sources cited by the New York Times and Scientific American.)
The average summer high in the Phoenix is already a few degrees higher now than it was in the 1970s, and the warming in and around Maricopa County has been faster than average:
