When Will Greenland's Ice Disappear? Scientists Are Racing to Find Out
Briefly

The GreenDrill expedition, stationed on the Greenland ice sheet, is focused on drilling through ancient ice to reach bedrock. This process is critical for understanding the dynamics of ice-sheet retreat and the implications for global sea levels. Positioned on the Northeast Greenland Ice Stream— which contributes significantly to sea level rise— the expedition reveals concerns that the ice sheet is losing mass annually. Observations suggest a troubling trend of accelerated retreat, heightening fears of future flooding as climate change continues to impact polar regions.
Inside a tent on Greenland's ice sheet, the GreenDrill expedition seeks to drill through ancient ice to examine the bedrock, crucial for understanding climate impact.
The Northeast Greenland Ice Stream drains a significant portion of the ice sheet into the ocean, and if melted, it could raise global sea levels by 24 feet.
