sciencehabit writes: Subtlety doesn't seem to be reigning at this weeks meeting of the American Geophysical Union. Professor of geophysics and complex systems Brad Werner of the University of California, San Diego, has livened up this year's conference with a suggestive title talk. Drawing on Werner's computer modeling of the relationship between human society and environmental systems, "Is Earth F**ked? Dynamical Futility of Global Environmental Management and Possibilities for Sustainability via Direct Action Activism" makes some disturbing conclusions. (Asterisks are included in the official title of the talk.) "[T]he dynamics of the global coupled human-environmental system within the dominant culture precludes management for stable, sustainable pathways and promotes instability," Werner's abstract says. This appears to suggest the answer to his provocative question, then, is yes. At press time, AGU had not responded to a request for comment about the title.
