Climate scientists wonder why people don’t do more about global warming. Social scientists have some tough answers
By Lisa Bennett
Three years ago, I became obsessed with global warming. Practically overnight, my worries about its potential effects outstripped my worries about so many other national and global issues, even personal ones.
Indeed, as the mother of two young boys, I began to think it a bit crazy that I attended to every bump and scrape of my children’s little bodies and budding egos, but largely ignored the threat likely to put sizeable areas of the world underwater within their lifetime.
That year, 2005, marked a turning point for many people. After decades of observation, speculation, and analysis, the world’s climate scientists had reached a consensus, and increasingly the general public was accepting it. As USA Today reported, “The Debate is Over: Globe is Warming.”
The next step, scientists advised, was action. We needed to take significant and urgent steps to cut our dependence on fossil fuels by 25 percent or more, something NASA’s top climate scientist, James Hansen, said we had only a decade to do if we were to avoid the great global warming tipping point – that level at which increased temperatures would unleash unprecedented global disasters.
Since then, surely some things have changed. Sales of hybrids have skyrocketed. Many of us have converted to the new energy-saving compact fluorescent light bulbs. A flood of books are hitting the market offering tips about how to save the Earth. And there is a frenzy of advertising about everything from “eco-friendly” houses to “green” hair salons.
Yet, none of this adds up to the significant action scientists have called for, which raises the question: Why don’t more of us respond more seriously to the most serious threat to the planet in human history?
“Many climate scientists find the response to global warming completely baffling,” says Elke Weber, a Columbia University psychologist and the chair of the Global Roundtable on Climate Change’s Public Attitudes/Ethical Issues Working Group.
But a growing number of social scientists are offering some explanations. Among the factors they point to: the way we’re psychologically wired and socially conditioned to respond to crises makes us ill-suited to respond to the abstract and seemingly remote threat posed by global warming. Their insights are also leading to some intriguing recommendations about how to get people to take action, including the potentially dangerous prospect of playing on people’s fears.
Our misleading emotions
“Risk-analysis scholars” believe there are, in general, two ways people assess a risk. One is through our analytic abilities, by which we examine the scientific evidence and make logical decisions about how to respond. Climate scientists, for example, used this process when they concluded that the risks of global warming are momentous.
But most of us do not rely on our analytic abilities, but instead on the more common way of perceiving risk: our emotions.
“For most of us, most of the time, risk is not a statistic. Risk is a feeling,” says Weber. We are swayed by our feelings, and those feelings – while an essential part of the decision-making process – can be misleading guides, depending on the type of risk involved. “If I feel scared,” adds Weber, “that overshadows any amount of pallid statistical information.”
Moreover, as decades of behavioral decision research has shown, most people have to feel a risk before they do something about it.
And this presents a particular challenge in the case of global warming, says Weber, because our emotions are shaped by past experience, either personal or evolutionary. But we have no past experience that tells us that when we burn too many fossil fuels, it will lead to catastrophic changes to the Earth.
“Global warming doesn’t make evolutionary sense to us,” says Weber. “Our minds haven’t adjusted to the much more complex technological risks that are removed in space and time.”
A second factor: Global warming is not a clear and present danger but, rather, something that is projected to reveal its most dramatic consequences decades from now.
Finally, worldviews shape how we perceive and respond to risk. A group of scholars from Yale and elsewhere have found, for example, that egalitarians, or people who prefer a society where wealth, power, and opportunity are broadly distributed, are more concerned about global warming, whereas hierarchists, who prefer a society with leaders on top and followers below, tend to be less concerned.
More to the point, the researchers discovered that when proposed solutions to global warming clash with people’s worldviews, those people are more likely to reject evidence of the problem altogether. “People spin the information to keep their worldview intact,” says Paul Slovic, founder and president of Decision Research.
Fearful futures, hopeful actions
With such significant obstacles in play, what can social scientists recommend about how to inspire the response we need to global warming?
First, several suggest, messaging needs to reach people’s emotions and trigger fear about the dramatic consequences to come. Specifically, this means making future hardships vivid, personalized and credible, says Slovic. For example, he suggests addressing: “How will it change the whole economy and whole quality of life in a particular region? Will the forests die out? Will the summers be so hot and dry that the Earth will be uninhabitable?”
But where one sets out to evoke fear, one must tread judiciously. “If people are being scared without seeing a way out, it makes them dysfunctional and freeze,” says Weber, which leads to a second recommendation: People need to be offered a set of actions they can take.
Finally, there needs to be a greater effort to address the large-scale lifestyle changes that will make a significant difference. “I don’t want to have to make a zillion little decisions,” says Baruch Fischoff of Carnegie Mellon University and former president of the Society for Risk Analysis. Rather, “I’d like to see people working out for me some alternative ways of organizing my life where it will really be a sustainable way to live.” This, Fischoff suggests, is the practical work that now lies ahead for both climate and social scientists.
As for ordinary Americans like myself, I believe that significant collective action on global warming will come from a very personal place – such as love for our kids, who will, after all, be among those most likely to experience its greatest consequences. But perhaps even more significantly, I’m finding hope in knowing that the drive to protect our children is another universal desire for which most of us are, in fact, hardwired.
