Greenland's Glaciers in Crisis: Rapid Melting Revealed in Before-and-After Photos

A study published in the journal Nature Climate Change reveals that Greenland's glaciers have experienced a rapid rate of retreat, which has accelerated over the past two decades. By comparing historical aerial photographs dating back to the 1930s with satellite images of Greenland today, researchers found that the rate of glacial retreat in the 21st century has been twice as fast as in the 20th century. The study highlights the alarming pace at which the Arctic is warming and changing, emphasizing the need for swift action to reduce emissions and limit global temperature rise to mitigate the future loss of glaciers and their contribution to sea level rise.
