Summary:
- A new study warns that a massive tsunami up to 650 feet high could hit Greenland's northwest coast if a large landslide occurs in a fjord.
- The landslide could be triggered by climate change-induced melting of glaciers, which could destabilize the steep fjord walls and cause a huge section to collapse into the water.
- Such a tsunami would pose a significant threat to nearby communities and infrastructure, highlighting the need for improved monitoring and preparedness in the region as the climate continues to change.
