Greenland Ice Sheet Crevasses Accelerate Melt: A Rising Sea Level Threat
2025-02-10
Numerous studies in recent years highlight the accelerating role of crevasses in Greenland's ice sheet, significantly contributing to ice calving and exacerbating sea level rise. Researchers have employed diverse methods, including satellite imagery, airborne LiDAR, and field observations, to investigate crevasse formation, expansion, and hydrological impacts. Findings reveal that crevasses not only compromise ice sheet stability but also expedite meltwater drainage, further accelerating ice melt. This poses a significant challenge to the future of the Greenland Ice Sheet and presents a major threat to global sea level change and coastal safety.
