This aerial view shows the glacier known as Agua Negra, in the Andes mountain range in Calingasta, San Juan province, Argentina, on April 22, 2026, composed of exposed ice in its upper section and debris-covered ice in its lower section. The ever-blue sky of San Juan is no longer reflected in many of its rivers: the Argentine province is facing a persistent water shortage due to climate change, while mining advances across the Andes and its thousands of glaciers.
