An animation from the Cooperative Institute for Research in Environmental Sciences makes clear that though there have been variations over time, the current rise is unparalleled. The animation zooms in on the graph of temperatures, often times referred to as the Hockey Stick for its distinctive shape, and shows the granular changes over time.
