Indian Cardinal Oswald Gracias of Mumbai, president of the Federation of Asian Bishops' Conferences, signed the appeal Oct. 26 at the beginning of a joint news conference at the Vatican.
The appeal, Cardinal Gracias said, was a response to Pope Francis' letter on the environment and an expression of "the anxiety of all the people, all the churches all over the world" regarding how, "unless we are careful and prudent, we are heading for disaster."
The appeal is addressed to negotiators preparing for the U.N. Climate Change Conference in Paris Nov. 30-Dec. 11. The bishops called for "courageous and imaginative political leadership" and for legal frameworks that "clearly establish boundaries and ensure the protection of the ecosystem."
The bishops also asked governments to recognize the "ethical and moral dimensions of climate change," to recognize that the climate and the atmosphere are common goods belonging to all, to set a strong limit on global temperature increase and to promote new models of development and lifestyles that are "climate compatible."
The appeal calls for decisions that place people above profits, that involve the poor in decision making, that protect people's access to water and to land, are particularly mindful of vulnerable communities and are specific in commitments to finance mitigation efforts.
Colombian Cardinal Ruben Salazar Gomez of Bogota, president of the Latin American bishops' council, spoke of the "suffering" Amazon basin and the key role it plays in the survival of South America and the world. The Latin American bishops, he said, want an end to pollution, to the destruction of the forests and the disappearance of biodiversity, but they also want justice for their people, the majority of whom do not benefit from the exploitation of resources taken from their countries.
Archbishop John Ribat of Port Moresby, Papua New Guinea, president of the Federation of the Catholic Bishops' Conference of Oceania, told reporters, "We come from islands, and our life is very much at risk."
"We belong to those most vulnerable groups impacted by rising sea levels," he said. Many communities -- particularly on Tuvalu, Kiribati and the Carteret Islands -- already are experiencing the disappearance of land used for subsistence farming or seeing their agricultural land rendered unusable by the infiltration of salt water.
Climate change, the archbishop said, already is leading to the phenomenon of climate refugees.
The appeal said that most people -- whether or not they believe in God -- recognize the planet as "a shared inheritance, who(se) fruits are meant to benefit everyone. For believers, this becomes a question of fidelity to the creator, since God created the world for everyone."
Miami Archbishop Thomas G. Wenski, chairman of the U.S. bishops' Committee on Domestic Justice and Human Development, confirmed that the U.S. bishops asked that a specific temperature target not be in the appeal. Others agreed, he said.
"We're pastors and we're not scientists," the archbishop said. The specific temperature target for reversing the impact of climate change is something for scientists to decide, but the need to act is a moral issue, and the bishops are competent to speak to that, he said.
People in the United States are starting to understand how important action is, Archbishop Wenski said. It has been slow because "we live in a little bit of a cocoon sometimes, and if it doesn't affect us immediately, we don't react."
Archbishop Richard Smith of Edmonton, Alberta, represented the Canadian bishops at the presentation. His province, Alberta, is "fossil fuel central," he said, yet people in Alberta, like in the rest of Canada, recognize that something must be done.
"Nobody wants the future placed in jeopardy because of this, and everyone understands intergenerational responsibility," he said.
"Everybody knows that we have to move away from fossil fuels," he said, but the big question is how. "There are some great minds out there working on finding the new technologies" that will provide jobs and energy without harming the environment.
