Climate change gets clocked

Within 35 years, global average temperatures will be hotter than historical extremes.

    That is one finding of a study published today in Nature1, which attempts to create a region-specific index of climate change. Researchers sought to identify the point at which temperature oscillations in each area will exceed the bounds of historical variability. Such ‘climate departures’ are predicted to start in the tropics and then spread to higher latitudes. If carbon dioxide emissions continue unabated, Earth’s mean climate could depart from historical averages in 2047.

    “Very soon, extreme events will become the norm,” says lead author Camilo Mora, an environmental researcher at the University of Hawaii at Manoa.
