Summary:
- Glacial lakes in Alaska are growing in size due to climate change. As glaciers melt, the water collects in lakes at the base of the glaciers.
- The size of these glacial lakes has increased by over 50% in the past 20 years, posing a risk of sudden flooding if the lake walls collapse.
- This is an example of how climate change is impacting the environment, with melting glaciers leading to the formation and expansion of dangerous glacial lakes.
