In the afternoon of October 1, at the Focolare Movement’s International Mariapolis Center in Castel Gandolfo, Rome, the Raising Hope Conference was inaugurated with the participation of His Holiness Leo XIV, alongside notable figures such as Arnold Schwarzenegger, former Governor of California, and the Hon. Marina Silva, Brazil’s Minister of Environment and Climate Change.

The session combined testimonies, spiritual and artistic moments, in thanksgiving for the 10th anniversary of the encyclical Laudato Si’. Representing the Laudato Si’ Movement, Associate Director Christina Leaño and Brazil Director Igor Bastos presided over the day’s opening.

A symbolic moment came when Pope Leo XIV touched and blessed a block of ice more than 20,000 years old, broken off due to climate change from a glacier in Greenland, as well as water brought from around the world—gestures embodying compassion and concern for the cry of the Earth and the poor.

Laudato Si’: What remains to be done?

“This Encyclical has profoundly inspired the Catholic Church and many people of goodwill,” Pope Leo began in his speech on Laudato Si’, “it opened strong dialogue, reflection groups, and academic programs.” The Pope noted how his predecessor’s encyclical spread “to international summits, to ecumenical and interreligious dialogue, to economic and business circles, to theological and bioethical studies.”

Giving thanks to the Heavenly Father “for this gift we have inherited from Pope Francis,” Leo stressed that today environmental and social challenges are even more urgent. On this anniversary we must ask ourselves: “What remains to be done? What must we do now to ensure that caring for our common home and listening to the cry of the earth and the poor do not appear as passing trends or, worse still, are seen and felt as divisive issues?” he asked.

Return to the heart: from data collection to care

“Today more than ever it is necessary to return to the heart, the place of freedom and authentic decisions,” affirmed the Pontiff, because although it “includes reason,” it also “transcends and transforms it.” “The heart is where external reality has the greatest impact, where the deepest search takes place, where the most authentic desires are discovered, where one’s ultimate identity is found, and where decisions are forged.”

In this regard, he stressed that “only by returning to the heart can a true ecological conversion take place.” “We must move from collecting data to caring; and from environmental discourse to an ecological conversion that transforms both personal and community lifestyles.”

Leo reminded those present that this experience of conversion orients us toward the living God: “We cannot love God, whom we do not see, while despising His creatures. Nor can we call ourselves disciples of Jesus Christ without sharing His vision of creation and His care for all that is fragile and wounded.”

No room for indifference or resignation

Before concluding, the Pope looked with hope to the upcoming international summits —COP30 in 2025, the World Food Security Committee session, and the 2026 Water Conference— “so that they may listen to the cry of the earth and the cry of the poor.”

He also encouraged young people, parents, and those working in administrations and institutions to contribute to “finding solutions to today’s cultural, spiritual, and educational challenges, always striving tenaciously for the common good.”

Finally, he reflected: “God will ask us if we have cultivated and cared for the world He created and for our brothers and sisters. What will our answer be?”

1.5 billion Catholics can get involved

Actor and former Governor of California, founder of the USC Schwarzenegger Institute and the Schwarzenegger Climate Initiative, Arnold Schwarzenegger, began his address by congratulating the Holy Father for installing solar panels on the roofs of the Vatican: “I am standing next to a hero,” he declared.

“There are 1.5 billion Catholics — that power and strength must be used to get involved in the climate movement,” Schwarzenegger said, urging more focus on talking about pollution: “The average person doesn’t understand when we talk about net zero or rising temperatures. Instead of speaking to the head, we must speak to the heart. We can end pollution if we work together, because God put us on this Earth to make it a better place.”

Toward the COP of hope

Next came the Hon. Marina Silva, Brazil’s Minister of Environment and Climate Change, co-chair of COP30. In her address, she expressed being inspired by Christian values in taking part in the conference.

Confidently, she stated: “I am certain that the Pope will make a great contribution so that COP30 goes down in history and becomes, as we all ardently hope, the COP of hope, to preserve and cultivate all forms of life that are part of the beautiful garden God has given us.”

From tears to hope

On stage, the Pope was joined by Dr. Lorna Gold, Executive Director of the Laudato Si’ Movement and President of the Conference Organizing Committee; theologian Margaret Karram, President of the Focolare Movement; Fr. Jesús Morán; and Yeb Saño, Chair of the Board of the Laudato Si’ Movement, who shared his own story of facing climate catastrophes in the Philippines and introduced the testimonies.

A symbolic spiritual moment followed when representatives from East Timor, Ireland, Brazil, Zambia, and Mexico brought water from their homelands, poured into a common bowl on stage. They embodied the cry of indigenous peoples, wildlife, ecosystems, future generations, migrants, the poor, and the Earth itself.

From tears to hope, with the audience on their feet, Pope Leo approached the glacial ice and proclaimed a blessing over the water and all present: “May we work for the flourishing of all creation.” Musical performances by Adenike, Gen Verde, and the Pacific Artists for Climate Justice brought joy and energy to the encounter.

A block of Greenland’s ice

The ice traveled more than 5,000 kilometers from the fjords of Nuuk, Greenland, to Castel Gandolfo, Rome. Artist Olafur Eliasson organized the transfer with the support of geologist Minik Rosing. Collected from the Nuup Kangerlua fjord, the block of ice had detached from the Greenland ice sheet due to climate change and was melting into the ocean.
Greenland’s vast ice sheet is one of Earth’s most important climate regulators. Formed from compacted snow over tens of thousands of years, it contains layers more than 100,000 years old with ancient air bubbles recording the history of our atmosphere. NASA’s Earth Observatory estimates Greenland’s ice sheet is losing about 270 billion tons per year due to climate change.
As the ice releases meltwater into the ocean, it reminds us that our global relationship with ice sheets is existential: they connect us to the past, shape our present climate, and —depending on our care or neglect— will determine our common future. If the ice melts completely, NASA predicts sea levels could rise by about seven meters (23 feet), reshaping coastlines and displacing millions worldwide.
