In January 2006, my wife Susannah Sayler and I set out to photograph landscapes around the world that were being transformed by global warming. We called our work The Canary Project. From the beginning, as now, we had both activist aims and artistic ambitions. These two types of motivation overlap in places and in other places feel completely distinct. In general, we feel as though are carrying forward a torch that science cannot carry any further. Following are some thoughts on our role as activists and as artists and as collaborators with the scientific community.
