Animation shows global warming spiraling out of control

A new graphic boils down 166 years of data into a stunning 15-second animation that shows just how quickly global warming is spiraling out of control.Ed Hawkins, a British climate scientist from the University of Reading, created the graphic to illustrate how global average temperature has changed since 1850.The animation initially shows tight spirals closer to the center of the image, before the circle expands slowly outward beginning in the 1940s, then rapidly beginning in the 1990s.”The pace of change is immediately obvious, especially over the past few decades,” Hawkins wrote on his blog, the Climate Lab Book.The animation uses data from the Hadley Centre of the United Kingdom’s Met Office to show average monthly global temperature departures compared to a baseline of pre-industrial temperatures from 1850 to 1900. It displays the changes in Celsius.
