**Nuuk, Greenland** – A groundbreaking study published in the Proceedings of the National Academy of Sciences has revealed that Greenland’s iconic ice sheet has melted completely in the recent past, likely less than 1 million years ago. This contradicts long-held scientific beliefs and raises serious concerns about the ice sheet’s vulnerability to climate change.

The discovery was made by analyzing a 30-year-old ice core, known as GISP2, taken in 1993. Scientists found fossilized remnants of plants and insects within the core, including willow wood, insect parts, fungi, and remarkably preserved Arctic poppy seeds.

“That is a tiny flower that’s really good at adapting to the cold,” explained Halley Mastro, a doctoral student involved in the research. “It lets us know that Greenland’s ice melted and there was soil because poppies don’t grow on top of miles of ice.”

The presence of these organic remains provides direct evidence that Greenland was once ice-free and hosted a thriving ecosystem. “We now have direct evidence that not only was the ice gone, but that plants and insects were living there,” said Paul Bierman of the University of Vermont. “And that’s unassailable. You don’t have to rely on calculations or models.”

This new understanding of Greenland’s history paints a stark picture of the ice sheet’s fragility. “This new study confirms and extends that a lot of sea-level rise occurred at a time when causes of warming were not especially extreme,” stated Richard Alley of Penn State, who was not involved in the research. He warns, “It is providing a warning of what damages we might cause if we continue to warm the climate.”

The findings underscore the pressing need to address climate change and mitigate its impacts. The melting of the Greenland Ice Sheet could significantly contribute to rising sea levels, threatening coastal communities around the globe. This discovery serves as a stark reminder of the delicate balance of Earth’s climate and the urgency of tackling the climate crisis.
