High-altitude mountain glaciers keep records of our climate and environment captured in ice.
But as climate change causes temperatures to rise, many glaciers are retreating, threatening this treasure trove of scientific data in mountain regions around the world.
In response, a team of scientists is rushing to extract ice cores from glaciers threatened by global warming. This Ice Memory project aims to create the first world library of archived glacier ice.
During the project’s most recent expedition, fifteen researchers from around the world journeyed more than 6,300 meters above sea level to the Illimani glacier in Bolivia. From May 22 to June 18, scientists were able to recover two ice cores down to bedrock, each more than 400 feet in length. Lack of time kept the team from successfully drilling a third.
