Earth's temperature history as a roller coaster


Basically everything that we think of as “modern human civilization”—permanent agriculture, continuously occupied cities, free WiFi—has emerged since the last ice age ended roughly 11,000 years ago. One question we get a lot is how do current temperatures compare to temperatures people have experienced in the period of modern civilization. 

We covered this topic in an article that we published in 2014, but we decided to revisit the question in animated form for a "Data Stories" competition sponsored by Science Magazine in April 2016. The animation was selected by the magazine's editor as a finalist in the "People's Voice" competition. (You can vote for it through April 29, 2016!) 

The rollercoaster mirrors the shape of a graph of paleoclimate data reconstructed by Shaun Marcott and several other scientists in a paper they published back in 2013. We chose the metaphor of a rollercoaster to convey the idea of relative speed of change and to show how fast recent temperature change has occurred compared to other changes humans have experienced during the Neolithic.
