Italy’s Ventina glacier has melted so much that scientists can no longer measure it in person as they have done for the past 130 years.
Climate change has caused the glacier, located in northern Italy, to shrink more than one mile in length since measurements began in 1895.
Researchers at the Lombardy Glaciological Service must now monitor the glacier using drones and remote sensing.
