Pope Leo XIV Criticises Climate Change Deniers and Calls for Global Action
Pope Leo XIV has strongly rebuked individuals who downplay or dismiss the growing impact of climate change, delivering his first major statement on the issue since assuming the papacy.
Speaking at a climate conference near Rome, the pontiff warned against ignoring what he described as the “increasingly evident” consequences of rising global temperatures. Echoing the views of his predecessor, Pope Francis, he criticised those who mock or dismiss concerns about global warming.
His remarks, delivered in Castel Gandolfo, were widely interpreted as an indirect response to comments made by Donald Trump, who recently described climate change as a “con” during a speech at the United Nations.
Climate debate becoming more polarised
The Pope expressed concern that discussions around climate change are becoming increasingly divisive. Referencing earlier teachings from Pope Francis, he highlighted how some critics ridicule climate science and even place blame on vulnerable populations who are most affected by environmental damage.
His address marked the 10th anniversary of Laudato Si’, a landmark encyclical that placed environmental protection at the heart of the Catholic Church’s mission. The document is widely credited with influencing global climate discussions ahead of the Paris Agreement.
Call for public pressure on governments
Pope Leo XIV emphasised that addressing climate change requires not only political leadership but also active public engagement. He urged citizens worldwide to hold decision-makers accountable and push for stronger environmental policies.
According to the Pope, meaningful progress can only be achieved if individuals take responsibility and participate in shaping political decisions. Without such involvement, he warned, efforts to reduce environmental damage would fall short.
He also framed climate action as a moral and spiritual responsibility, suggesting that individuals will ultimately be judged on how they have cared for the planet and for one another.
Global context and upcoming climate talks
The speech took place just weeks before the upcoming COP30 climate summit in Belém, Brazil, where global leaders are expected to discuss strategies to reduce greenhouse gas emissions and address the climate crisis.
Brazil’s environment minister, Marina Silva, has invited the Pope to attend the summit, expressing hope that his presence could play a significant role in advancing global climate action.
During the conference, former California governor Arnold Schwarzenegger also praised the Pope’s environmental commitments, noting initiatives such as installing solar panels across Vatican buildings.
A moral message on climate responsibility
Pope Leo XIV concluded his remarks by urging humanity to reflect on its responsibility toward future generations. He stressed that protecting the environment is not optional but a duty, warning against indifference in the face of mounting climate risks.
His message reinforces the Vatican’s continued stance that climate change is both a scientific reality and a moral challenge requiring urgent, collective action.
