This article cites a research which shows how Brown Glacier on sub-Antarctic Heard Island is retreating rapidly. It suggests that local climatic conditions are continuing to change rather that stabilize. Measurement of the basic physical characteristics of Brown Glacier commenced in November 2000. The results showed that compared with 1950, the glacier has lost 38 percent of its volume and retreated 1.17 km at an average rate of 21 m per year. The retreat is attributed to an increase in average annual temperatures of about one degree Celcius.

    The article discusses the study which examined the digital elevation models (DEMs) of the ablation area of Hailuogou glacier, China. It states that the data on DEMs were taken from Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) in 2009. The study found that the overall...

    Proglacial areas in the Alps usually cover a time span of deglaciation of about 150 years (time since the end of the "Little Ice Age" in the 1850s). In these proglacial areas soils have started to develop. In view of the foreseeable climate change, the time factor is of growing interest with...

    The article presents a case study on the environmental changes of the Raikot Glacier in the Nanga Parbat massif in northern part of Pakistan in response to global climate changes from 1934 to 2007. It provides a documentation and an analysis of fluctuations and dynamics of the area using a...

    The article discusses a study which investigated the problem of extracting a climatic trend from a glacier mass balance using a variance decomposition. An expansion of Lliboutry's model was proposed and the use of hierarchy for the isolation of the annual terms was illustrated. The 20-30% of the...
