The Glaciers The world is melting at a record rate of global warming, losing 267 billion tons of ice annually since 2000, according to A study published in the journal Nature.
This is the main conclusion of the work carried out by an international group led by researchers from the Laboratory of Geophysics and Space Oceanography Studies of the French National Center for Scientific Research (CNRS).
The researchers found that the reduction Glaciers It has accelerated in recent years, from 227 billion tons of ice lost annually between 2000 and 2004 to 298,000 between 2015 and 2019.
These results are the result of the first complete and accurate mapping of thickness, and thus mass, evolution of all Glaciers Scientist, the CNRS statement explained.
The Glaciers The fastest melting has been found since 2000 in the Alps, Iceland and Alaska.
Instead, the scientists found that melting rates decreased on the east coast of Greenland, Iceland and the Scandinavian region in 2010-2019.
The researchers pointed out that “this local slowdown may be due to meteorological anomalies that increased precipitation and decreased temperatures, thus slowing the loss of ice” in that region.
They determined that “the regional variation in mass loss is determined to a large extent by changes in precipitation. Conversely, the global acceleration of mass loss” Glaciers It is the result of high temperatures. “
Scientists conducted this research with half a million images taken by the NASA Terra satellite, which allowed them to create a series of digital models of altitude Glaciers.
These new observations will clarify the predictions for evolution Glaciers In this way, the experts concluded, to improve forecasting of changes in water resources for some mountainous regions.
