🏔️ As glaciers melt, they don’t just vanish. They reshape the land itself, redirecting rivers, creating new hazards, and worsening existing ones. What you are seeing: a “before and after”, from 2003 to 2024, shows the Berg Lake’s drainage changing as Alaska’s Steller Glacier retreats, forcing the water to find new drainage routes. Why this matters: as the glacier thins and recedes, these shifting “plumbing systems” increase the risk of sudden and destructive glacial lake outburst floods (GLOFs) that can affect people, infrastructure, and communities downstream. What happens in Alaska’s cryosphere is not an isolated case, and this is why #Glaciers2025 matters: these changes echo globally, underscoring the urgent need for #ClimateAction.
