Summary

Description
English: This image shows the termini of the glaciers in the Bhutan-Himalaya. Glacial lakes have been rapidly forming on the surface of the debris-covered glaciers in this region during the last few decades. USGS researchers have found a strong correlation between increasing temperatures and glacial retreat in this region.

According to a joint press release issued by NASA and the U.S. Geological Survey, the great majority of the world’s glaciers appear to be declining at rates equal to or greater than long-established trends. This image from the ASTER (Advanced Spaceborne Thermal Emission and Reflection Radiometer) instrument aboard NASA’s Terra satellite shows the termini of the glaciers in the Bhutan-Himalaya. Glacial lakes have been rapidly forming on the surface of the debris-covered glaciers in this region during the last few decades.
According to Jeffrey Kargel, a USGS scientist, glaciers in the Himalaya are wasting at alarming and accelerating rates, as indicated by comparisons of satellite and historic data, and as shown by the widespread, rapid growth of lakes on the glacier surfaces. According to a 2001 report by the Intergovernmental Panel on Climate Change, scientists estimate that surface temperatures could rise by 1.4°C to 5.8°C by the end of the century. The researchers have found a strong correlation between increasing temperatures and glacier retreat.


Français : Image de l'instrument ASTER (Advanced Spaceborne Thermal Emission and Reflection Radiometer) embarqué à bord du satellite Terra de la NASA montrant l'extrémité des glaciers hymalayens du Bhoutan.

Depuis quelques décennies, des lacs glaciaires se forment rapidement sur la surface couverte de débris de ces glaciers. Les scientifiques de l'USGS (United States Geological Survey) ont montré une forte corrélation entre la montée des températures et le retrait des glaciers dans la région. En Himalaya, les glaciers reculent a une vitesse alarmante et de plus en plus importante, ce qui est établi par la comparaison des données actuelles et historiques, ainsi que par la multiplication et la croissance rapide des lacs de surface de ces glaciers, selon Jeffrey Kargel, de l'USGS.
La grande majorité des glaciers du monde reculent a une vitesse supérieure aux anciennes tendances. Ce recul est fortement corrélé avec l'augmentation des températures. Selon le rapport de 2001 du GIEC (Groupe International sur le Changement Climatique), la température de surface du globe terrestre devrait augmenter de 1.4 à 5.8°C d'ici la fin de ce siècle.
