WASHINGTON (October 9, 2013)---Scientists have figured out when temperatures could really go off the charts as a result of global warming, and for dozens of cities it's only about a generation away, according to a study released Wednesday.
For Kingston, Jamaica, it's 2023.
In Singapore its 2028.
For Mexico City its 2031, for Cairo 2036 and for Phoenix and Honolulu 2043.
Researchers at the University of Hawaii came up with the dates after looking at 150 years of record-keeping and then calculating when cities and ecosystem across the world would regularly experience never-before-seen hotter environments.
For example 2005 was the world’s hottest year on record, but the study in the journal Nature says that by the year 2047 every year will likely be warmer than that record-setting scorcher.
