New Glacier App

In the forefront of the Paris Climate Conference COP21 in December 2015, the WGMS and UNESCO jointly launched a Glacier App for mobile devices. This new information system aims at bringing scientifically sound facts and figures on worldwide glacier changes to decision makers at governmental and intergovernmental levels as well as reaching out to the interested public.
