Glacier meltdown risks food and water supply of 2bn people, says UN

The UN warns that retreating glaciers pose a serious threat to the food and water supply of 2 billion people globally. A Unesco report highlights that two-thirds of irrigated agriculture could be impacted due to the climate crisis, with more than 1 billion living in mountainous regions facing heightened food insecurity. The Colorado River basin in the U.S. exemplifies developed nations' vulnerabilities too. As glaciers and mountain snow recede, the urgency for action against these unprecedented changes is paramount, with the fastest glacier mass loss occurring in recent years, particularly in Norway, Sweden, and the Andes.

"Two-thirds of all irrigated agriculture in the world is likely to be affected in some way by receding glaciers and dwindling snowfall in mountain regions, driven by the climate crisis."
