A 2005 study by Anthony Leiserowitz, published in Risk Analysis, found that while most Americans are moderately concerned about global warming, the majority—68 percent—believe the greatest threats are to people far away or to nonhuman nature. Only 13 percent perceive any real risk to themselves, their families, or their communities. As Leiserowitz points out, this perception is critical, since Americans constitute only 5 percent of the global population yet produce nearly 25 percent of the global carbon dioxide emissions.

12 ASTEROIDS AND EVOLVING INTO WISDOM IN 2004, JOHN SCHELLNHUBER, distinguished science adviser at the Tyndall Centre for Climate Change Research in the United Kingdom, identified 12 global-warming tipping points, any one of which, if triggered, will likely initiate sudden, catastrophic changes across the planet. Odds are you've never heard of most of these tipping points, even though your entire genetic legacy—your children, your grandchildren, and beyond—may survive or not depending on their status.
