First Study Links Human Activity to Antarctic Glacier Retreat
A new study by scientists at King's College London and the British Antarctic Survey is the first to directly link human activity, specifically greenhouse gas emissions, to the retreat of a major Antarctic glacier. The research on Pine Island Glacier found that human-driven ocean warming amplified its retreat by 18-20% since the 1940s, accounting for approximately 4 kilometers of its withdrawal by 2015.
Why it matters
This study represents a significant breakthrough in attribution science, providing concrete evidence of human impact on large-scale Antarctic ice sheet dynamics. These findings are crucial for improving predictions of global sea level rise and informing climate change mitigation strategies.
Scientists at King's College London and the British Antarctic Survey have published the first study to directly attribute the retreat of a major Antarctic outlet glacier to human activity . The research, led by Dr. Alex Bradley and published in The Cryosphere, focuses on Pine Island Glacier, which drains a large portion of the West Antarctic Ice Sheet into the Amundsen Sea and is among the largest single contributors to global sea level rise. The study found that greenhouse gas emissions (ghg) increased the glacier's retreat by approximately 18% to 20% since the 1940s, accounting for roughly 4 kilometers of its landward withdrawal by 2015 .
