Within Decades, Historic Heat Will Be the Global Norm

Get used to hearing about historically hot temperatures. Using 39 of the world’s foremost climate models, researchers have developed "climate departure" dates for cities around the world to predict when temperatures will exceed historical norms.

"Scientists from the University of Hawaii at Manoa calculated that by 2047, plus or minus five years, the average temperatures in each year will be hotter across most parts of the planet than they had been at those locations in any year between 1860 and 2005," reports Justin Gillis.

“Go back in your life to think about the hottest, most traumatic event you have experienced,” Camilo Mora, the lead scientist on a paper published in the journal Nature said in an interview. “What we’re saying is that very soon, that event is going to become the norm.”

The good (?) news: "The models show that unprecedented temperatures could be delayed by 20 to 25 years if there is a vigorous global effort to bring emissions under control. While that may not sound like many years, the scientists said the emissions cuts would buy critical time for nature and for human society to adapt, as well as for development of technologies that might help further reduce emissions."
