LISTEN TO THE TREES addresses the impact of climate change on San Diego's ecology. The installation focuses on two trees, the coastal Torrey pine, and the Jeffrey pine growing in the inland mountains. Photomontages line the walls, while tree stumps offer visitors a place to sit and contemplate the scene. On one stump an ipad touch screen displays diagrams of the tree rings of these two species based on historical data and models projecting future climate under differing emissions scenarios.
