Greenland’s Ice Sheet Offers New Insights on Climate Change

Speedy Summary

• Since 2002, five and a half trillion tons of ice have melted from Greenland’s ice sheet.
• Satellites have monitored the mass loss for over 20 years; though, scientists remain uncertain about how the ice sheet might collapse.
• Greenland’s ice sheet harbors roughly 24 feet of global sea-level rise in its frozen mass. Understanding how it breaks apart is critical for predicting future climate impacts.
• A scientific expedition known as “GreenDrill,” based at Columbia University and the University at Buffalo, aims to investigate Greenland’s ice sheet by drilling through the layers to examine bedrock underneath.
• This research reveals that cosmic ray-exposed isotopic signals within bedrock beneath thes ice sheets can provide insights into when the region was covered by or free of glacial mass in past climate periods.
• Previous findings (e.g., from rock samples analyzed in 2016) suggest Greenland’s vast ice cover disappeared entirely during parts of geologic history-that process likely occurred much faster than anticipated.
• Researchers are seeking further clarity on these melt dynamics because even partial melting could lead to meaningful societal impacts such as sea level rise and displacement in coastal areas worldwide.
