The following is a presentation that I gave at The GLOBAL WARNING symposium, organized by ZER01: The Art and Technology Network, the City of San Jose Public Art Program and CADRE Laboratory for New Media at San Jose State University in collaboration with LEONARDO/ISAST, with additional support from the Montalvo Arts Center in September, 2010. Full details can be found here. The presentation was motivated by the somewhat widely held opinion that uncertainty in science, and especially the issue of current global warming and climate change, is something which should not be communicated to the broader public. I do not hold that opinion, and here I try to explain why I both personally, and as a scientist, choose to embrace uncertainty in my everyday life.
