Each row is a location with its annual-stripe SVG (175 years, 1850–2024). Select a place for a cited local result: 1° grid cell, record window, 1951–1980 baseline, trend, data-through date, Berkeley Earth / HadCRUT citations, and the historical-grid-cell boundary — not a local hazard forecast. Featured cities still expand to monthly detail.
The URL stores loc, filters, and cmp. Reload restores without geolocation. Copy link / Download SVG / Download PNG are built in-browser from the existing stripe asset. Blue = cooler than the 1951–1980 baseline, red = warmer.
