Doomsday – 2047

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. A new study on global warming pinpoints the probable dates for when cities and ecosystems around the world will regularly experience hotter environments the likes of which they have never seen before.

Study author Camilo Mora and his colleagues said they hope this new way of looking at climate change will spur governments to do something before it is too late. Now is the time to act, said another study co-author, Ryan Longman.

Mora, a biological geographer at the University of Hawaii, and colleagues ran simulations from 39 different computer models and looked at hundreds of thousands of species, maps and data points to ask when places will have “an environment like we had never seen before.”
