The Himalayas and nearby peaks have lost no ice in past 10 years, study shows | Environment | The Guardian

The scientists are careful to point out that lower-altitude glaciers in the Asian mountain ranges - sometimes dubbed the "third pole" - are definitely melting. Satellite images and reports confirm this. But over the study period from 2003-10 enough ice was added to the peaks to compensate.

So :

1. the glaciers of the Himalaya are definitely receding, the measurements on the ground show this (and led to the inaccurate mass estimates).
   
2. the satellite that allows them to measure this is only there since 2002. You can't get a useable trend out of 8 years of data.
