Today (Friday, June 21) is not only the Summer Solstice for the Northern Hemisphere, but it is also Show Your Stripes day as meteorologists and scientists from around the world raise awareness about climate change.
Meteorologists across the world have been using the hashtag #MetsUnite to show how average temperatures have changed over time across the globe. This is an effort to bring awareness to climate change by showing temperatures changes in an easy and simple way.
Each stripe on the pictures attached to this article shows a year of recorded temperature data. Red signifies above average and blue signifies below average temperature departures. The bolder the shading is, the larger the departure from average in a year for that specific location.
The photos (below) show the states of New York and Pennsylvania and their yearly temperature departures from 1895 through 2018.
You can note a large amount of deep red shadings over the last 20 years. Actually, 16 out of the last 20 years the state of New York has seen yearly average temperatures above normal. Similarly, Pennsylvania has held above average yearly temperatures for 17 out of the last 20 years.
This “warming stripe” graphic was created by the group Climate Central as they analyzed 160 cities to produce the images above. Climate Scientist Ed Hawkins helped implement this simple visual to communicate the story of our warming planet.
These graphics show for almost every location, our planet is indeed warming and climate change is not only a local theory, but it is also happening across the entire globe.
