As part of the 10th anniversary celebrations for Early Warning Signs all four signs were brought to Glasgow and installed at various community venues across the city in the run-up to COP26. The green on black sign was installed at The Hidden Gardens. This was the second time the Gardens had hosted a sign, having looked after the yellow on black sign for six months in 2012. For Glasgow Open House Arts Festival on Saturday 25 September 2021, Harrison led a special Bike & Talk event around Glasgow to visit the four signs - from Woodlands Community Garden in the West End to Impact Arts in the East End and then to The Bowling Green and The Hidden Gardens in the Southside.
At the end of October 2021, the 10th anniversary celebrations will conclude when all four signs are re-united for first time since the project began at Artsadmin in 2011 at one central location in Glasgow for COP26.
Applications are now being sought for a host venue for this sign in 2022. If you would like to follow in the footsteps of Artsadmin in London, Dundee Contemporary Arts, Scotland's Travelling Gallery, the Gallery of Modern Art (GoMA) in Glasgow, Spike Island in Bristol, Arcola Theatre in London, ONCA in Brighton, UH Arts in Hertfordshire, Central Saint Martins in London, PEER and Hoxton Trust in London, Royal Botanic Garden Edinburgh and now The Hidden Gardens too, then please see further information about how to 'adopt a sign'.
