In a passionate address, Pope Leo XIV emphasized the urgent need for the world to unite against climate change, as he faced criticism from skeptics, including Donald Trump. During a climate justice conference, the pontiff performed a symbolic blessing of a block of ice, aiming to draw attention to environmental issues despite mockery from some critics. Arnold Schwarzenegger joined the pope at the Vatican, echoing the call for actions to combat pollution and support ecological initiatives. Pope Leo urged onlookers to embrace a ‘true ecological conversion’ and criticized inhumane immigration practices in the U.S., reinforcing the need for compassionate and global stewardship of the earth. As the climate debate grows increasingly contentious, Pope Leo’s stance positions him firmly against climate skepticism, rallying not only Catholics but all people to take meaningful steps towards safeguarding the planet.
