New satellite data on melting of Himalayan glaciers

(Phys.org)—There is consensus among scientists that the glaciers in the Himalayas and Tibet are shrinking, but there is disagreement on the extent of the shrinkage because of the difficulty in interpreting satellite data. In 2010 satellite data from the Gravity Recovery and Climate Experiment (GRACE) satellite was analyzed and the researchers concluded the glaciers were losing around 50 billion tonnes of ice each year, but the same data was interpreted earlier this year by another team of researchers who concluded the annual loss of ice was around five billion tonnes.
