“Only 3% of World's Glaciers Cause Over Half of Ice Loss, Study Finds” — what this page in the network covers. A new study reveals that a tiny fraction of the world's glaciers—just 3.2%—are responsible for more than half of all glacier ice loss. These are glaciers that end in lakes, oceans, or ice shelves, known as marine- or lake-terminating glaciers. Between 2000 and 2019, they lost an average of 134 billion metric tons (148 billion tons) of ice per year.
That staggering figure accounts for the majority of global glacier mass loss, despite these glaciers representing a small portion of the total number. The findings highlight how water at glacier fronts accelerates melting, making these glaciers critical drivers of sea-level rise. The study underscores the urgent need to monitor these vulnerable ice bodies, as their retreat has far-reaching implications for coastal communities and ecosystems worldwide.
