Climate scientist Ed Hawkins tells the story behind his “climate stripes” graphic, a striking visual that has appeared on everything from badges to cars, which illustrates how global temperatures have changed since 1850. Each stripe represents the average temperature for a single year, relative to the average temperature over the period as a whole, with blue stripes showing cooler-than-average years, and red showing the years that were hotter than average. #climate #climatestripes #showyourstripes #temperaturerise
