Using simple graphic representations of annual temperatures (like this one posted by climate scientist Ed Hawkins), people are knitting and crocheting blankets that show just how warm the Earth has gotten over the past few decades. See Katie Stumpf’s blanket, for example.
According to climate scientist (and crocheter) Ellie Highwood, these blankets are a subset of “temperature blankets” made to represent, for example, daily temperatures over the course of a year in a particular location. The blanket she crocheted used NOAA data of global mean temperature anomalies for a 101-year period ending 2016.
I then devised a colour scale using 15 different colours each representing a 0.1 °C data bin. So everything between 0 and 0.099 was in one colour for example. Making a code for these colours, the time series can be rewritten as in the table below. It is up to the creator to then choose the colours to match this scale, and indeed which years to include. I was making a baby sized blanket so chose the last 100 years, 1916-2016.
If you read her post, she provides instructions for making your own global warming blanket.
P.S. You might think that with the Earth’s atmosphere getting warmer on average, these blankets would ironically be less necessary that they would have been 50 years ago. But climate change is also responsible for more extreme winter weather events — think global weirding in addition to global warming. So keep those blankets handy!
