Watch the World's Temperatures Spiral Out of Control

Noticing how the climate is shifting is difficult on a day-to-day basis. But squeeze more than a century of world-temperature data into a half-minute, and the signal becomes as cartoonishly clear as watching a patient’s fever bust right through a thermometer’s bulb.

“Temperature Anomalies” lends a rather neutral name to an astounding portrayal of how the globe has warmed from 1900 to 2016. Made by Antti Lipponen, a 33-year-old researcher at the Finnish Meteorological Institute, the visualization shows each country’s monthly temperature readings, starting with the shortish, chilly-looking blue bars of the early 1900s and progressing to long, angry-red lines pumping all over the place in recent years. (As a reminder, the planet has now experienced three years of back-to-back, record-breaking heat.)
