Local warming stripes

These warming stripes, created by Professor Ed Hawkins (University of Reading), show the temperature change in Merthyr Tydfil, from 1884 to 2023. Each stripe represents the average temperature for a single year, relative to the average temperature over the period as a whole. Shades of blue indicate cooler-than-average years, while red shows years that were hotter than average. The stark band of deep red stripes on the right-hand side of the graphic show the rapid heating in recent decades.
