The pamphlet was drawn by Robbie Morrison and handed out to members of the public at a Greenpeace local groups table in Brixton and Streatham, south London, United Kingdom in the following weeks. The pamphlet represents an early example of climate campaigning by lay persons and predates the first IPCC report by several months. Home computing was also quite rare at that time, hence the hand writing. The original TIFF scans were later converted to PDF. The transcript was appended on 27 May 2021. The notion of a tipping point is encaptured by the phrase "our climate could flip to another mode with disastrous effects for all life" (page 4).

Version 2 corrects typos in the appended transcript.
