 Glaciers in the Ak @-@ <unk> Range in Kyrgyzstan experienced a slight loss between 1943 and 1977 and an accelerated loss of 20 % of their remaining mass between 1977 and 2001 . In the Tien Shan mountains , which Kyrgyzstan shares with China and Kazakhstan , studies in the northern areas of that mountain range show that the glaciers that help supply water to this arid region , lost nearly 2 km3 ( 0 @.@ 48 cu mi ) of ice per year between 1955 and 2000 . The University of Oxford study also reported that an average of 1 @.@ 28 % of the volume of these glaciers had been lost per year between 1974 and 1990 .
