Ice dam in Alaska

Severe flooding in Juneau, Alaska, was triggered by the failure of an ice dam created by the Mendenhall Glacier, affecting at least 100 homes and businesses. The flooding, described as the worst in the city’s history, saw cars submerged and residents scrambling to evacuate as waters reached chest-high levels. This annual phenomenon is linked to the retreat of a smaller glacier that has created a basin which fills with rainwater and snowmelt each summer. Experts note that while climate change has contributed to glacial retreat, it plays a minimal role in the year-to-year variations of flooding intensity. The National Weather Service reported that the river crested at 15.99 feet, higher than last year, but the floodwaters receded quickly, prompting cleanup efforts. Authorities are monitoring for potential pollution threats as they assess damage and assist affected residents.
