Mig provided a link that showed the global effects of sea level increases up to 7 meters. I believe that such a link that showed the effects of a 70 meter rise might be useful to show people what their great, great grandchildren, if any, could be inheriting. Just because we will all be dead does not mean that we can abandon concern for posterity. Perhaps one of the benefits of increased life span could be a heightened concern for future generations, more of whom some of us might see. If sanity be culturally normative, then by the norms of this culture I claim insanity.
