“We are pushing the ecosystems … out of the environment in which they evolved ‘

FRISCO — Starting with the tropics, many locations on Earth will start to see new climate normals within the next few decades — Kingston, Jamaica could reach that point within the next decade, and other well-known cities, including Singapore, Mexico City and Phoenix will see off-the-chart temperatures by mid-century, according to climate scientists and geographers with the University of Hawaii, Manoa.
Their study, published Oct. 10 in Nature, creates an index of the year when the mean climate of any given location on Earth will shift continuously outside the most extreme records experienced in the past 150 years.
The index used the minimum and maximum temperatures from 1860-2005 to define the bounds of historical climate variability at any given location. The scientists then took projections for the next 100 years to identify the year in which the future temperature at any given location on Earth will shift completely outside the limits of historical precedents, defining that year as the year of climate departure.
“The results shocked us. Regardless of the scenario, changes will be coming soon,” said lead author Camilo Mora. “Within my generation, whatever climate we were used to will be a thing of the past.” (more…)
