Climate report says Boston summers could feel like Miami by end of century

Think it's hot outside right now? By the end of the century, summertime Boston could feel as hot as Miami, a new report warns.

Future summers in cities across the U.S. could see even more blistering temperatures by the end of the century, according to the report by the non-profit group Climate Central.

The effects of climate change are not as far off as most would like to think. Summers today are already hotter than they were in the 1970s, with average temperatures increasing 0.4 degrees per decade in the U.S. The analysis shows that future Americans could see an average increase of 7 to 10 degrees in summer high temperatures -- with some cities as much as 12 degrees hotter -- by the year 2100.

"Summer temperatures in most American cities are going to feel like summers now in Texas and Florida -- very, very hot," Alyson Kenward, the lead researcher of the project, said in a press release.

Las Vegas and Phoenix could experience the worst of it. In the future, the report said Las Vegas could feel like Saudi Arabia does today, with average summer highs reaching a scorching 111 degrees. Phoenix, where summertime temperatures could regularly hit a sweltering 114 degrees, would feel like modern-day Kuwait City.

The researchers say the projected temperatures were based on the assumption that greenhouse gas emissions continue increasing as they have for the past several decades. They also calculated how temperatures might change if emissions slow, based on scenarios used by the U.N.'s Intergovernmental Panel on Climate Change (IPCC). In either case, they found that "U.S. cities are already locked into some amount of summer warming through the end of the century."
