glacier, Shukla, Rakesh Mishra and Ajai Kumar analyse the hourly melt water discharge data collected using area-velocity technique, during the August-September
period spanning between 2000 and 2007. The studies indicate close linkages with
temperature and surface ice ablation.
Sharat Dutta and his co-workers in their paper on Responses of Indian Summer
Monsoon (ISM) Dynamics and Late Quaternary Fluvial Development: Records
from Yamuna River valley, NW Himalaya, describe three to four major periods of
sediment dispersal and aggradation in the Yamuna Valley under warm climatic conditions. They report enhanced ISM activity during these phases and conclude that
the continuation of palaeo-floodplain across MCT and MBT suggests profound climate control of sediment generation, dispersal and aggradations.
In the final paper An Appraisal of Spatio-temporal Characteristics of Temperature
and Precipitation over NW Himalaya Using Gridded Datasets, Negi and Neha validate the performance of eight gridded datasets, over NW Himalaya (NWH) within
the Indian subregion and then study spatio-temporal variability of climate through
the use of these selected datasets. They find that ERA-I and CRU-TS datasets capture the spatial distribution of temperature and precipitation well. They further add
that temperature and precipitation trends pre- and post-year 2000 reveal comparative slowdown in warming/rate of precipitation decline after year 2000 which is
linked with increased snow cover area and comparatively less negative glacier mass
budget in westerly dominated areas like NWH.
Overall, the book Climate Change and the White World provides a comprehensive overview of scientific studies conducted by researchers in different areas related
to impact of climate change on Antarctic, Arctic and the Himalaya and on people
around. However, a lot more scientific attention is needed to substantially comprehend the complex interplay of manmade interventions with the natural world.
