Are you a crafty person? Have you ever wondered how you can bring the reality of climate change to life?
Wonder no more, friends! Meet the Tempestry Project!
The Tempestry Project allows you to visualize “climate data in a way that is accurate, personal, tangible and beautiful.”
“Uh… what,” you say? It’s a marriage of crafting and climate change activism! Hooray!
Temperature Tapestries
Each Tempestry is a knitted tapestry of temperature data. You select your location and your year, and the Tempestry Project folks will send you the temperature highs for each day that year.

For example, I ordered a Tempestry kit for Geneva Switzerland, 1985. My kit arrived with an Excel spreadsheet with 365 lines, starting January 1st 1985, ending December 31st. Each line shows the date, the day’s high temperature, and which color you need to knit to correspond to that temperature.
The original kit also includes a color card (pictured above) with little yarn samples, and just the right amount of each color yarn for you to knit your full Tempestry.
Knit or Crochet (or Cross Stitch!)

You can choose either to knit or crochet your Tempestry. If you decide to knit, you can also choose whether to do it in garter stitch or linen stitch.
The lovely thing about the linen stitch is the texture it gives the whole Tempestry. The pattern recommends a small 3-stitch garter stitch border with the linen stitch, and I’m loving the way it looks.
Really, you can knit or crochet this any way you choose. You just have to be conscious that you only have a certain amount of each yarn. This project is easy to adapt and personalize.
Giving Climate Change Data Context
What this project does is it allows you to contextualize climate change data. If you’re like me and you struggle to see how climate change awareness and activism can fit into your daily life, then this might help.
I mentioned my kit for Geneva, 1985. I also ordered one for Geneva, 2017, because some extraordinary circumstances meant that our second son, our Bear, was born in Geneva in 2017 (we were expecting him to be born in Germany).
It will be interesting to see how these two kits compare once they’re knitted. How much warmer was Geneva in 2017 than in 1985? I remember it being hot as hell in 2017, especially as I traipsed around town the morning of the Bear’s birth, unaware that I was going to deliver a baby later that afternoon. The Tempestries should illustrate the difference.
A Tutorial for Your Tempestry
I discovered the Tempestry Project from Staci Perry over at VeryPink Knits. She published a video tutorial for knitting a Tempestry, and her colleague Casey from the (now defunct) VeryPink podcast interviewed the crew at the Tempestry Project.
I’m sharing Staci’s tutorial below, in case anyone is interested. Her YouTube channel has been my go-to resource for knitting lessons.
Other Ways to Participate
There are lots of other ways to participate in the Tempestry project. They sell their very own needle wranglers, as well as other patterns and kits on their websites.
They’ve developed a “new normal” series, which show “a visual representation of annual deviations-from-average temperature for different locations.” Some of the results are pretty nuts.
This is a great project, and a great way to dip your toes into what is now being called “craftivism.” More on that another time, perhaps.
