2º is an exhibition about climate change. It includes eight artists who are far from sceptics (obviously) and have produced works that express their personal concerns, with blunt messages on global warming, using a diversity of materials very effectively.While Søren Dahlgaard’s The Inflatable Island which travels the world drawing attention to rising sea levels is a scene stealer, the suspense of David Buckland’s melting iceberg is chilling in every sense of the word. Annika Harding’s paintings on corrugated cardboard follow her recent travels from one extra extreme climate to another while Jacky Green (Borroloola), Daniel Bonson and Timothy James Johnson (Maningrida) (NT) focus on how everything got hotter as their traditional lands (and as a consequence their cultures), have been degraded by unbridled industrial activity. With coal and steel, Andrew Styan and G.W. Bot explore processes by which the use of natural materials from under the surface of the earth create environmental problems above. Both have produced astonishingly clever installations of disturbing beauty. While 2º might ultimately paint a bleak picture of our future there is something quite edifying about the innovative ways artists have approached the “great moral, environmental and economic challenge of our age” (thanks Kev). For this reason alone, and whether you believe climate change is caused by humans or not, 2º is essential viewing. 2º is a CCAS in house effort curated by Alexander Boynes and supported by Climate.org who promote the arts for a safe environment through their international networks. At CCAS Gorman Art Centre until 20 August.
