RT Report T1 High mountain glaciers and climate change: challenges to human livelihoods and adaptation A1 United Nations Environment Programme, K1 glacier K1 climate change K1 mountain ecosystem K1 snow K1 climate change adaptation PB United Nations Environment Programme SN 978-82-7701-087-8 YR 2010 FD 2010 LK https://wedocs.unep.org/handle/20.500.11822/8101 UL https://wedocs.unep.org/handle/20.500.11822/8101 NO Climate change is causing significant mass loss of glaciers in high mountains worldwide. Although glacier systems show a great amount of inherent complexity and variation, there are clear overall trends indicating global glacier recession, which is likely to accelerate in coming decades. Large gaps remain in our understanding and ability to model accurately the key processes and cause-effect relationships driving glacier response to climate change. In addition, a lot of data on glacier mass changes are not available to the public due to national interests concerning water supply. DS UN Environment Document Repository RD Sep 16, 2026
