THE LATEST INTELLIGENCE

2015 was the hottest year since

records began. But what’s driving

this change? NASA might have the

definitive answer. The Goddard

Institute for Space Studies has built a

climate change model that allows

them to isolate potential culprits and

estimate their contributions. We’ve

plotted their data below to illustrate

how natural variables like volcanic

activity and solar variations compare

with man-made factors.
