I read the statement below after a round of knocking on church doors to pitch a local screening of The Great Warming to pastors and priests — yes, thank you, I did feel a bit silly. Anyway, Moab’s 8,000 residents are served by 19 official houses of worship (you can find the less-organized believers at the co-op). By and large, churchgoers here vote, and they’re pretty pro-active, especially when it comes to the health and welfare of the canyons.

Rick Sherman, a Catholic priest who’s written on stewardship for a few newspapers, was quick to point out that his church has been on the environmental ball for years, and handed me a few pamphlets on the subject. Not having read many religious tracts lately, I was impressed — and not scared a bit! This is from Global Climate Change: a plea for dialogue, prudence and the common good, a statement from the U.S. Catholic Bishops. Yes, it’s a serious read, but it’s not Latin and there’s no math.

As Catholic bishops, we make no independent judgment on the plausibility of “global warming.” Rather, we accept the consensus findings of so many scientists and the conclusions of the Intergovernmental Panel on Climate Change (IPCC) as a basis for continued research and prudent action. Scientists engaged in this research consistently acknowledge the difficulties of accurate measurement and forecasting. Models of measurement evolve and vary in reliability. Researchers and advocates on all sides of the issue often have stakes in policy outcomes, as do advocates of carious courses of public policy. News reports can oversimplify findings or focus on controversy rather than areas of consensus. Accordingly, interpretation of scientific data and conclusions in public discussion can be difficult and contentious matters.

Responsible scientific research is always careful to recognize uncertainty and is modest in its claims. Yet over the past few decades, the evidence of global climate change and the emerging scientific consensus about the human impact on this process have led many governments to reach the conclusion that they need to invest time, money, and political will to address the problems through collective international action.

The virtue of prudence is paramount in addressing climate change. This virtue is not only a necessary one for individuals in leading morally good lives, but is also vital to the moral health of the larger community. Prudence is intelligence applied to our actions. It allows us to discern what constitutes the common good in a given situation. Prudence requires a deliberate and reflective process that aids in the shaping of the community’s conscience. Prudence not only helps us identify the principles at stake in a given issue, but also moves us to adopt courses of action to protect the common good. Prudence is not, as popularly thought, simply a cautious and safe approach to decisions. Rather, it is a thoughtful, deliberate and reasoned basis for taking or avoiding action to achieve a moral good.

In facing climate change, what we already know requires a response; it cannot be easily dismissed. Significant levels of scientific consensus – even in a situation with less than full certainty, where the consequences of not acting are serious – justify, indeed can obligate, our taking action intended to avert potential dangers. In other words, if enough evidence indicates that the present course of action could jeopardize humankind’s well-being, prudence dictates taking mitigating or preventative action.

This responsibility weighs more heavily upon those with the power to act because the threats are often greatest for those who lack similar power, namely, vulnerable poor populations, as well as future generations. According to reports of the IPCC, significant delays in addressing climate change may compound the problem and make future remedies more difficult, painful and costly. On the other hand, the impact of prudent actions today can potentially improve the situation over time, avoiding more sweeping action in the future.
