This captivating video created by Antti Lipponen visualizes more than 100 years of temperature change in 191 countries in just 35 seconds.
Lipponen, a researcher at the Finnish Meteorological Institute, used publicly available data from NASA to demonstrate the rising temperatures across the world.
In Lipponen’s graphic, the color and length of a bar represent the same thing: the average temperature anomaly of each country each year.
By using anomaly data (instead of absolute temperature data), Lipponen makes it easy to see how each country’s temperature at any given point differs from a baseline.
Admittedly, if you’re trying to get an idea of what this all means for global temperature rise, you can’t just average the bars. Some relatively smaller temperature rises in large countries contribute more to mean global temperature than do larger rises in smaller countries. And different regions are affected differently by climate change.
But a broad trend is startlingly clear, and Lipponen inserts a smaller graphic in the upper right-hand corner to show it: It’s getting hotter all around the world.
