Starting in about a decade,Kingston, Jamaica, will probably be off-the-charts hot _ permanently. Other places will soon follow. Singapore in 2028. Mexico City in 2031. Cairo in 2036. Phoenix and Honolulu in 2043.
And eventually the whole world in 2047.
For example, the world as a whole had its hottest year on record in 2005. The new study, published Wednesday in the journal Nature, says that by the year 2047, every year that follows will probably be hotter than that record-setting scorcher.
The 2047 date for the whole world is based on continually increasing emissions of greenhouse gases from the burning of coal, oil and natural gases. If the world manages to reduce its emissions of carbon dioxide and other gases, that would be pushed to as late as 2069, according to Mora.
But for now, Mora said, the world is rushing toward the 2047 date.
``The first U.S. cities to feel that would be Honolulu and Phoenix, followed by San Diego and Orlando, Florida. in 2046. New York and Washington will get new climates around 2047, with Los Angeles, Detroit, Houston, Chicago, Seattle, Austin and Dallas a bit later.
Mora calculated that the last of the 265 cities to move into their new climate will be Anchorage, Alaska _ in 2071. There's a five-year margin of error on the estimates.
