A new study reveals that Greenland’s ice sheet, which melted by 90% over the last million years, heightens the catastrophic risk predictions for rising sea levels. The discovery of plant, insect, and fungal remains beneath three kilometers of ice provides undeniable evidence of this event. Most of Greenland’s ice sheet disappeared during the last million years when greenhouse gas concentrations were lower than today, indicating that the ice sheet is more fragile than scientists previously thought. This is the key conclusion of a study published in PNAS, offering the first direct evidence that the central part (not just the edges) … Continue reading Greenland’s Ice Sheet Shrinks by 90%, Revealing Ancient Seeds and a Potential Six-Meter Sea Level Threat
