Pope Francis on Climate Change and Ecology

Integral Ecology Advocate (strong)

Pope Francis expresses a strong conviction that climate change is real and that it is mainly a consequence of human activity. He explicitly stated this position in his landmark 2015 encyclical, Laudato Si’, declaring the problem urgent and warning against the consequences of continued inaction for future generations.

Central to his thinking is the principle of integral ecology, which mandates that the environmental crisis cannot be separated from issues of social injustice. He repeatedly calls for hearing "the cry of the earth and the cry of the poor," emphasizing that ecological degradation and human suffering are two dimensions of the same complex crisis.

Consequently, Pope Francis urges a decisive action, here and now, from all people and world leaders to stop environmental ruin. This involves advocating for systemic changes in development, consumption, and politics, alongside a profound interior and cultural conversion toward simplicity, responsibility, and care for creation.

Context

Pope Francis’s focus on ecology is deeply rooted in his chosen name, Francis of Assisi, who is the patron saint of ecology. This choice immediately set a tone for his papacy, signalling a commitment to caring for the natural world.

His encyclical, Laudato Si', is a significant part of Catholic Social Teaching, but it is novel because it is the first social encyclical addressed to all people, not just Catholics, framing the crisis as a global dialogue.

His emphasis is on integral ecology, meaning that economic, social, and environmental issues are interconnected, demanding solutions that uplift the marginalized alongside protecting the planet.
