This bracelet encodes data on global warming in the city of Arkhangelsk over the past few decades. Each pair of rows represents a year, and the color of the beads codes the temperature difference from a baseline value in the past. The darker and redder the beads, the more the temperature for that year deviates positively from the norm; the bluer the beads, the more they deviate negatively. In essence: red beads represent hot years, and blue beads represent cool years. This method, known as Warming Stripes, was popularized by Ed Hawkins. Since then, it has become popular among eco-activists and data visualizers to create such warming stripes from various materials, primarily knitting scarves!

This project was challenging but incredibly interesting! I had long wanted to try creating handmade data art, but knitting something seemed too difficult (beading turned out to be no easier...).
