Are our leaders, in both the public and private sectors, condemning humans to extinction?
Diamond weaved an all-encompassing global thesis through a series of fascinating historical-cultural narratives. Moving from the Polynesian cultures on Easter Island to the flourishing American civilizations of the Anasazi and the Maya and finally to the doomed Viking colony on Greenland, Diamond traces the fundamental pattern of catastrophe. Last summer however, James Hansen—the pioneer of modern climate science—pieced together a research-based revelation: a little-known feedback cycle between the oceans and massive ice sheets in Antarctica and Greenland might have already jump-started an exponential surge of sea levels. That would mean huge levels of sea level rise will happen sooner—much sooner than expected. Hansen’s best estimate was 2 to 5 meters (6–15 feet) by the end of the century: five to 10 times faster than mainstream science has heretofore predicted.
