  1. Two heatmap-style graphs depict monthly temperature extremes for Lake Superior from 1941 to 2021. The y-axis represents months (1 to 12), and the x-axis shows years. "Degree heating days (°C·days)" are shown in the heat waves plot using a red color gradient, ranging from 0 (white) to 120 (dark red). Four notable heat waves are apparent before 1996, with five following 1996. Black lines indicate "breakpoints" or significant shifts in trends around 1970, 1986, 1996 and 2001. The cold spell plot shows "Degree cooling days (°C·days)" using a blue color gradient. Darker blue indicates more intense cold spells, with white corresponding to no anomaly and dark blue showing a -120 degree cooling day. Three intense cooling events are seen in the 1940s and early 50s, but largely vanish until 1996. The most intense heat waves and cold spells tend to happen in the summer for Lake Superior.
