AARP Magazine Asks: What Kind Of Planet Are We Leaving Our Children?

I dunno . . . how does "Dirty, Diminished and Dysfunctional" sound?

What’s driving the change in attitudes is a steadily growing body of scientific evidence on human activities and warming. A report released earlier this year by the Intergovernmental Panel on Climate Change—made up of hundreds of the world’s leading climate experts—said with 90 percent certainty that most of the warming since 1950 has been driven by the buildup of carbon dioxide and other greenhouse gases. The report concluded with “high confidence” that human-caused climate change was already affecting regional conditions from the poles to the Tropics, and that hundreds of millions of people could be harmed by coastal flooding, dwindling water supplies, and shifting weather patterns within a few decades. The changes could also drive many species toward extinction, particularly those with rapidly shrinking habitats, such as polar bears. Warming in this century, by many estimates, could be between three and eight times the warming in the 20th century, when the planet’s average temperature rose just over one degree Fahrenheit in all. The United States was among 113 countries that endorsed the report.

The new report also predicts a mix of consequences, not all bad. More rainfall and longer growing seasons will likely benefit higher latitudes for decades, while less rainfall and harsher droughts are likely in some of the world’s poorest places—most notably, Africa. An open-water Arctic Ocean in summers, while posing a threat to polar bears, could create new intercontinental shipping lanes thousands of miles shorter than existing ones. What the debate comes down to is not whether changes are coming but when they’ll occur—and how severe they’ll be. There is serious scientific disagreement about such vital questions as how fast and far temperatures, seas, and storm strength could rise. Warmer waters, for example, could lead to more Katrina-strength hurricanes. Yet new studies find that hurricanes might be torn apart by wind conditions associated with, yes, rising temperatures. This uncertainty is not humanity’s friend, experts say, especially as the global population crests in coming decades, putting ever more people at risk of flooding, famine, and other climate-driven threats.

“We’re altering the environment far faster than we can possibly predict the consequences,” says Stephen H. Schneider, 62, a Stanford University climatologist who has been working on the puzzle of humans and climate for more than half his life.

Schneider has long believed that responding to the greenhouse challenge is as much about hedging against uncertain risks as it is about dealing with what is clearly known. And the risks, as he sees it, are clear: there is a real chance things could be much worse than the midrange projections of a few degrees of warming in this century—and any thought that more science will magically clarify what lies ahead is probably wishful thinking. When he lectures about global warming these days, Schneider often asks listeners about a more familiar risk. “How many of you have had a serious fire in your home?” he begins. In a crowd of 300 or so, usually three or four hands rise. His next question: “How many of you buy fire insurance?” Hundreds of hands go up.
