Pope Leo criticises climate change sceptics and denialism
Pope Leo XIV has strongly criticised those who downplay or mock climate change, warning that the effects of global warming are becoming “increasingly evident” and cannot be ignored.
In his first major statement on the issue, delivered near Castel Gandolfo, the Pope echoed the message of his predecessor Pope Francis, condemning voices that ridicule climate science or shift blame onto vulnerable populations.
Without naming individuals directly, his remarks were widely interpreted as a response to comments made by Donald Trump, who recently dismissed climate change as a “con.” The Pope warned that such attitudes risk deepening divisions at a time when global cooperation is urgently needed.
Speaking at an event marking the 10th anniversary of Laudato Si'—a landmark document that placed environmental protection at the heart of Catholic teaching—Pope Leo stressed that climate change is both a moral and global responsibility.
He called on citizens worldwide to take a more active role in pushing governments toward stronger environmental action, arguing that there is no place for indifference or resignation in the face of a growing crisis.
The Pope also framed environmental stewardship as a matter of accountability, urging people to consider their responsibility to future generations and to care for both the planet and one another.
His intervention comes ahead of the upcoming COP30 in Brazil, where world leaders are expected to negotiate new steps to address rising emissions. Brazilian officials, including Environment Minister Marina Silva, have invited the Pope to attend, highlighting the influence of faith leaders in shaping the global climate debate.
The speech underscores growing concern within religious and political circles that climate change is becoming increasingly politicised, even as its impacts intensify worldwide.
