Act On Climate! Put this sticker on your water bottle, laptop, window, or notebook. Stickers are a sturdy vinyl that's weatherproof. The red and blue stripes are  the ‘warming stripes,’ created by Professor Ed Hawkins (University of Reading). They are visual representation of the change in global temperature over the past 100+ years (1850-2021). Each stripe represents the temperature that the world averaged over a year.
