Starting 15 Aug until a commencement of September, an general group of around 10 glaciologists and engineers – French, Italian, Russian and American – will be travelling to a Col du Dome (4,300 m or 14,108 feett) on Europe’s top peak, Mont Blanc to cavalcade ice cores. They are partial of a singular Protecting Ice Memory project, that is directed during sketch out prolonged tubes of ice from glaciers for their refuge in Antarctica. The purpose is to build a world’s initial library of ice repository extracted from glaciers that are threatened by tellurian warming.

“In a entrance decades, or even centuries, this ice repository will be useful – be it for wholly rare systematic discoveries or for bargain internal changes in a environment,” pronounced Jean Jouzel, climatologist and Vice-Chair of a IPCC, 2002-2015.

Three ice cores, any measuring 130 meters in length, will be extracted and lowered into a hollow by helicopter before being ecstatic to a LGGE in Grenoble, while progressing a despotic cold sequence via a process. One core will be analysed in 2019 to start building a database accessible to a whole universe systematic community. The other dual will be ecstatic by boat before being eliminated onto tracked vehicles on a high plateaus of Antarctica in 2020 for storage during a Concordia station, that is run by French and Italian scientists. The long-term devise is to have dozens of ice core repository stored in a sleet cavern during -54°C , that is a many arguable and healthy freezer in a world.

The Col du Dome glacier represents a initial step in this vital project, creatively launched in 2015 by a LGGE, Ca’ Foscari University of Venice (Italy) and a CNR (Italian National Research Council), corroborated by a Universite Grenoble Alpes Foundation. A second, longer and some-more formidable operation will be carried out in 2017 on a Illimani glacier in a Bolivian Andes. A series of other countries are already possibilities to join this devise and strengthen a memory of a glaciers to that they have access: Germany, Austria, Switzerland, Brazil, a United States, Russia, China, Nepal and Canada.

The thought to emanate this devise was innate when scientists celebrated a arise in temperatures on several glaciers. At ten-year intervals, a heat nearby to a glaciers on a Col du Dome and Illimani in a Andes has risen between 1.5° and 2°. At a stream rate, their aspect will bear systematic melting over a summer in a subsequent few years and decades. Due to this melting and a percolation of meltwater by a underlying layers of snow, these are singular pages in a story of a sourroundings that will be mislaid forever.

“We are a usually village of scientists operative on meridian to see a cube of a repository disappearing. We urgently need to build this birthright for a future, many like a Svalbard Global Seed Vault kept on a island of Spitsbergen,” explains Jerome Chappellaz, a French devise initiator from CNRS.

“Our era of scientists, that bears declare to tellurian warming, has a sold shortcoming to destiny generations. That is because we will be donating these ice samples from a world’s many frail glaciers to a systematic village of a decades and centuries to come, when these glaciers would have left or mislaid their information quality,” adds Carlo Barbante, a Italian devise initiator from Ca’ Foscari University of Venice.
