Temperature Tapestries
Knitting and crocheting data has proven to be a useful tool for activists as well, particularly when it comes to displaying climate data in an accessible and engaging way.
Marine scientist Joan Sheldon made a scarf as a high impact way of demonstrating climate change from the year 1600 to 2015. When she presented it at a conference, Joan explained that "Even scientists who were familiar with the data wanted to touch the scarf, to find the year they were born. “They never would [do this] with a science graph,” she says. “It approaches you in a different way.” See Dr. Sheldon's work here.
Dr. Laura Guertin of Penn State created the above crocheted graph of temperature as a poster for a conference in 2017. Calling them "Temperature Tapestries," Dr. Guertin wrote: "I was surprised at how easy it was to talk about changes in weather and climate with people with yarn as my tool."
