The so-called Warming Stripes, developed by climate scientist Ed Hawkins, represent a simple but concise symbolization to visualize climate change. For a given location or region, the average annual temperature is plotted chronologically since measurements began and displayed as color-coded stripes. The coldest year appears dark blue, the warmest dark red. It is easy to see that in recent decades the red stripes have increased. Currently, the years 1881-2021 are shown. The coldest year in Hilden was 1888 with 8.27 °C, the warmest was 2020 with 12.14 °C.
