Bowman Lake in Glacier National Park, Montana
In 1850, an estimated 150 glaciers covered the mountains that would later form Glacier National Park. Today, only 25 glaciers remain larger than 25 acres. Loss of glaciers--and their meltwater--can lead to more severe droughts in late summer. Since the beginning of the 20th century, the mean annual temperature at the park has risen 1.33°C, almost twice as fast as the global average.
