Browse the full atlas below. Each row is a location with its annual-stripe SVG (175 pixels = 175 years, 1850-2024). Click any location to expand the monthly-detail view (where available) — 2,100 pixels wide, one pixel per month.
How to read the stripes: Each colored vertical bar is one year’s average temperature anomaly relative to the 1951–1980 baseline. Blue = below average, red = above average. Darker = more extreme. The dramatic shift from blue-dominant left half to red-dominant right half is the climate signal.
