CLIMATE CHANGE BLANKET

Despite the fact that +97% of climate scientists agree that climate change is not only real, but likely due to human activities, many people still refuse to believe that Earth is getting warmer. Some of these people are our leaders and law-makers.

This is why I have crocheted a blanket showing the rise in global temperature over the last 130 years, using data provided by the NASA Goddard Institute of Space Studies.

Each hexagon represents a year. The colors represent the deviation from the mean (average) temperature from 1951 to 1980, shown by the green border, i.e. how much cooler or warmer each year has been compared to the mid-century average. These are factual data, not opinions or feelings.

This beautiful gradient is terrifying, because it shouldn’t exist. In a world with no climate change, this whole blanket would be light blue and pink. There shouldn’t be corals, reds and burgundies. But they are here, you can see that for yourself.

MAN-MADE CLIMATE CHANGE IS REAL..

-0.50º to -0.26º: Peacock (24 hexes)

-0.26º to -0.01º: Sky (48 hexes)

0.00º to 0.24º: Lady Slipper (26 hexes)

​​How to crochet a granny hex​

Note: the first dc of each round is worked as a ch3

Round 1: Magic double ring with (dc2, ch2) x 6; join with sl st. 

Round 2: Sl st to first ch2-sp; * work (dc2, ch2, dc2, ch1) in ch2-sp, repeat from * another 5 times; join with sl st - 12 dc clusters

Round 3: Sl st to first ch2-sp; * work (dc2, ch2, dc2, ch1) in ch2-sp, work (dc2, ch1) in ch1-sp, repeat from * another 5 times; join with sl st - 18 dc clusters

Round 4: Sl st to first ch2-sp; * work (dc2, ch2, dc2, ch1) in ch2-sp, work (dc2, ch1) in first ch1-sp, work (dc2, ch1) in second ch1-sp, repeat from * another 5 times; join with sl st, fasten off - 24 dc clusters

​​How to join granny hexes

A white border is worked around each hex in a join-as-you-go method 

Border: join in white yarn in any ch2 of hex with a sl st and ch2 (counts as first sc); work  (sc2, ch2, sc2, ch1) in ch2-sp and (sc2, ch1) in ch1-sp. 

For each sc2, joining is done by removing the hook after the last ch, inserting it into corresponding ch-sp of adjacent hex, inserting it back into the dropped loop to pull it up through ch-sp (shown by a red arrow), and continue with next sc (shown in red) 
Finishing the blanket​​

Weave in all the ends. Hand wash or machine wash on delicate only; lay flat to dry. Display it proudly.
