Religious fervor for curbing global warming and protecting the environment reached a confusing peak this week when a member of the Council for Culture at the Vatican announced that offsetting carbon emissions, which the Holy See will be able to do almost completely in the future thanks to a donation of land in Hungary to be planted with trees, is roughly parallel to doing penance for your sins. There’s nothing wrong and a good deal right with contemporary religious leaders pointing out our responsibilities to care for the Earth. But with all due respect to the good monsignor, it’s a very bad idea to suggest that steps to deal with environmental questions are like doing penance for sins.
Carbon emissions are not intrinsically wrong. All animals that inhale oxygen and exhale carbon dioxide do so by natural design all the time. Even cars, electricity generating plants, and mechanical appliances do much good in addition to adding to atmospheric greenhouse gases. Deciding when and how to use them is not like deciding to cheat on your wife, an intrinsic wrong that requires confession and penance. It’s more like deciding how much of the family income to allot for a better gas-mileage car, and how much for food, housing, healthcare, or education for the children. In other words, it’s always a choice among competing goods, not between good and evil, within limited resources.
In addition, though the potential negative consequences of global warming are worthy of serious consideration, they need to be put in the proper perspective of the actual nature of the world that God created. Temperatures on the earth have changed drastically without benefit of human intervention. In the multiple Ice Ages that have regularly occurred over geological time, glaciers miles thick covered Northern Europe and much of North America. At their retreat, they scraped the earth cleaner than any logging company would dare, but enabled the growth of the lovely boreal forests we prize today.
In historical times, the changes have been less drastic but still quite striking. Leif Eriksson found grapes growing in Newfoundland, which is why he called it Vineland. Other explorers seem to have had similar reasons for giving the frozen expanses of today’s Greenland its name. From just before 1000 A.D. and continuing for a few centuries, the earth experienced what is sometimes called a Medieval Climate Optimum, a period of significant warming that may have helped in the cultural recovery of Europe, followed by a cooler period called the Little Ice Age beginning in the sixteenth century and lasting until around 1850. Since then, the earth has generally warmed but with another cooling dip from around 1950 to 1975. These simple facts of geology are much cited by both sides in the debates about global warming. But it’s rare to find any religious figure who shows any familiarity with the fact that God did not create a world of stable climate where species and habitats are forever fixed and or that change represents anything other than a violation of, and perhaps a sin against, the created order.
NASA administrator Michael Griffin was vilified when he called it “rather arrogant” to assume that the present climate was optimal for human beings. Contrary to the claims of his critics, Griffin was not saying that global warming should not be examined carefully. What he was saying - that we need to calm down and examine evidence more fully - is so outside the generalized hysteria among the media and the political class that his opponents could not fathom it. A similar fate has befallen Bjorn Lomborg, whose just-released book Cool It looks to be a worthy sequel to his controversial The Skeptical Environmentalist. This statistician has tried to weigh the various potential harms and benefits of global warming, which he not only believes is occurring but concedes is significantly owing to anthropogenic causes. There are two unforgivable sins among the most fervid environmentalists. As Al Gore has taught us, one is being a global-warming denier, which is on a moral level with the Holocaust deniers. Deniers at least can be summarily excommunicated. But it is precisely the Lomborgs and his like who are more infuriating to a certain type of true believer. To acknowledge anthropogenic global warming and to believe it may be effectively handled through anything but curtailing global capitalism through reducing carbon emissions, or, even worse, that we ought to add some of global warming’s benefits to our deliberations seems, to some, on a par with calling evil good.
But the facts are the facts. In Cool It, for example, Lomborg analyzes the conditions that produced the thirty-five thousand deaths in Europe during the infamous and much reported on heat wave of August 2003. That was a great tragedy, but every year, in Europe and around the world, far more people die of cold. In August 2003, some two thousand Britons died from the heat; on average, twenty-five thousand Britons a year die of cold and in some years more than twice that figure. If you turn to any ordinary media outlet, you will hear the usual litany of impending catastrophes: twenty-foot sea rises owing to Greenland melting that will submerge Florida and Bangladesh; widespread famine and death because of changes in precipitation patterns; the spread of tropical diseases to warmer environments; and of course the disappearance of charismatic flora and fauna. This, we are told, is the scientific consensus that should tug at our heart strings, and only reduced carbon emissions can prevent such an apocalypse.
This is a mixture of truth and misapprehension. If the Greenland ice pack melts, for example, it will take one thousand years and over the next century will produce a sea-level rise of about one foot. Furthermore, it is not at all clear that this Greenland, which was naturally green around 1000 A.D., is being ravaged by human activity. Glaciation naturally varies a great deal in the Northern Hemisphere and similar doomsday scenarios were common in the 1930s, a naturally occurring warm period that preceded emissions of large quantities of greenhouse gases.
Our religious leaders cannot be expected to be experts in environmental sciences or policies. But it would be a great help toward a better climate debate if they made greater allowance for the complexities of creation and the inevitable trade-offs in policy decisions while calling us all to responsible action. Our technological developments have brought great benefits to the whole of humanity in the past century. Failure to spread those benefits further may be the greatest harm we can do to the poor and marginalized. And it is beyond question a mistaken application of a crucial religious notion to suggest that the costs of those benefits are, even metaphorically, like sins.
