Pope Francis passed away on Easter Monday, April 21, at the age of 88. He led the Catholic Church for over a decade, advocating for climate change awareness and addressing its impact on the world's poorest. His notable works include the 2015 document 'Laudato si'' and the recent 'Laudate Deum,' calling for urgent action against climate change. Despite health issues preventing him from attending COP28, he emphasized the moral responsibility of wealthy nations in addressing ecological debt. He organized a climate resilience conference in 2024, highlighting the disproportionate effects of climate change on poorer populations.
