The 12 tipping points are: 1. Amazon Rainforest 2. North Atlantic Current 3. Greenland Ice Sheet 4. Ozone Hole 5. Antarctic Circumpolar Current 6. Sahara Desert 7. Tibetan Plateau 8. Asian Monsoon 9. Methane Clathrates 10. Salinity Valves 11. El Nino 12. West Antarctic Ice Sheet

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.

EISEROWITZ'S STUDY OF risk perception found that Americans fall into "interpretive communities"—cliques, if you will, sharing similar demographics, risk perceptions, and worldviews.
-
On one end of this spectrum are the naysayers: those who perceive climate change as a very low or nonexistent danger. Leiserowitz found naysayers to be "predominantly white, male, Republican, politically conservative, holding pro-individualism, pro-hierarchism, and anti-egalitarian worldviews, anti-environmental attitudes, distrustful of most institutions, highly religious, and to rely on radio as their main source of news."
-
This group presented five rationales for rejecting danger: belief that global warming is natural; belief that it's media/environmentalist hype; distrust of science; flat denial; and conspiracy theories, including the belief that researchers create data to ensure job security

We might wonder how these naysayers, who represent only 7 percent of Americans yet control much of our government, got to be the way they are. A study of urban American adults by Nancy Wells and Kristi Lekies of Cornell University sheds some light on environmental attitudes. Wells and Lekies found that children who play unsupervised in the wild before the age of 11 develop strong environmental ethics. Children exposed only to structured hierarchical play in the wild—through, for example, Boy Scouts and Girl Scouts, or by hunting or fishing alongside supervising adults—do not. To interact humbly with nature we need to be free and undomesticated in it. Otherwise, we succumb to hubris in maturity. The fact that few children enjoy free rein outdoors anymore bodes poorly for our future decision-makers.

THE ALARMISTS AND THE ACROBAT ON THE OTHER END of Leiserowitz's spectrum of perception regarding global warming is an interpretive community he calls the alarmists, generally comprised of individuals holding pro-egalitarian, anti-individualist, and antihierarchical worldviews, who are supportive of government policies to mitigate climate change, even so far as raising taxes. Members of this group are likely to have taken personal action to reduce greenhouse gas emissions.
-
Collectively, alarmists compose 11 percent of Americans, with the remaining interpretive communities falling considerably closer to the alarmists than the naysayers in the spectrum—suggesting the gap might be cinched by sustained public education on the neighborhood dangers likely to arise in a changed global climate.

Hurricane Katrina provided a wake-up call for how bad it can get in the neighborhood, and may prove a tipping point itself.

Yet long before its rampage, American kids were coloring pictures of the first icon of global environmentalism, the Amazon. Its billion-plus acres of rivers and rainforest—its trees collecting and containing excessive greenhouse gases from the atmosphere—were our primer for the revolutionary notion that the earth's neighborhoods are interdependent. Today Amazonia is the most famous of Schellnhuber's tipping points. For a generation, kids have grown up learning that the Amazon is at risk from massive deforestation. But even if clearcutting were to halt, climate models forecast that a warming globe will convert the wet Amazonia forest into savanna within this century, and the loss of trees will render the region a net CO2 producer, further accelerating global warming.
