1. The encyclical strongly affirms the climate science and the gravity of the environmental challenge. The pope states clearly that the recent global warming is due to greenhouse gas emissions, caused mainly by human activity. He delves into the science, and even discusses risk factors like ocean acidification, the loss of tropical forests, and the release of methane from melting ice sheets. He calls climate change one of the principal challenges facing humanity in our day. Overall, the discussion of the environmental threats is deep and wide-ranging, with discussions of water, ecosystems, and biodiversity. In places, the diagnosis is characteristically blunt: “the earth, our home, is beginning to look more and more like an immense pile of filth”.
2. In the face of this crisis, the pope lambasts those who fail to act. Noting the failure to find solutions to the environmental crisis, Pope Francis pins the blame on obstruction by vested interests, general indifference, and blind confidence in technical solutions. He is particularly critical of people who possess more resources or more political and economic power, who seem concerned with “masking the problems or concealing their symptoms”. He notes that special interests trump the common good and manipulate information so that their own plans will not be affected. He criticizes a habit of evasiveness designed to feed “self-destructive vices”.
3. The encyclical calls for a dramatic reduction in the emission of greenhouse gases, and for rich countries to help poorer countries on this path. It notes that fossil fuels need to be “progressively and quickly replaced” with renewables. This requires action at the global, national, and local levels. Given the complete failure of governments to reach agreement almost a quarter century after the Rio Earth summit in 1992, the pope notes that “we believers cannot fail to ask God for a positive outcome to the present discussions”. Noting that the poor pay the price for climate change—and indeed, that an “ecological debt” exists between north and south—Pope Francis also calls for the richer countries, who have enjoyed prosperity at the cost of polluting the planet, to help the poorer countries overcome climate change and move to lower-carbon energy systems.
