Earlier this week Pope Francis convened a major conference in Rome on climate disruption. It is one of several events planned by the Vatican ahead of his much-anticipated encyclical on global warming and the environment. The conference included speeches by U.N. Secretary-General Ban Ki-moon and leaders of the pontifical academies, along with panels on the relevant scientific, moral, and economic issues.
The Vatican did not pull its punches In the run up to the conference or at the conference itself, signaling its determination to move the conversation to a new level of urgency.
Last month Cardinal Peter Turkson, who helped write the first draft of the encyclical, declared that global inequality and the destruction of the environment “are the greatest threats we face as a human family today.” “A changing of human hearts in which the good of the human person, and not the pursuit of profit, is the key value,” he insisted, would be required to meet these threats.
Striking a similarly resolute tone, the Vatican issued a statement at the close of the conference on Tuesday, emphasizing that “human-induced climate change is a scientific reality, and its decisive mitigation is a moral and religious imperative for humanity.” Pointing out that the climate summit in Paris later this year “may be the last effective opportunity to negotiate arrangements that keep human-induced warming below 2-degrees C,” it called for a rapid transition “to a world powered by renewable and other low-carbon energy and the sustainable management of ecosystems.”
The Pope’s encyclical on climate change will not be the first time that the Church has addressed this issue. But it is the first time that it will be the subject of an encyclical, which carries great authoritative weight for Roman Catholics.
The Vatican’s sustained engagement with the threat of global warming underscores the fact that science and technology can only take the discussion so far. They can explain the causes and consequences of climate destabilization and pose technical solutions. But it is values, especially a commitment to the generations that come after us, that will provide the motivation to implement the solutions, which are likely to be expensive and politically fraught.
Building a sustainable world, in short, is as much a cultural and ethical project as it is a scientific and engineering endeavor. It is a task that requires imagination, compassion, collaboration, and creativity, a willingness to live our lives differently. In Pope Francis’s words, “We need to care for the earth so that it may continue, as God willed, to be a source of life for the entire human family.”
