11. Glacier National Park (USA)
Glacier National Park in Montana was once home to over 100 glaciers; today, fewer than 30 remain. Warming temperatures have caused these ancient ice sheets to melt at an alarming pace, and scientists predict only a handful may survive the next few decades. This trend is not unique, echoing glacier loss in the Alps and New Zealand. The park’s changing landscape serves as a powerful reminder of our rapidly warming world.
