It's not good that they are putting stuff in the Impact section
which can not be found in the Science bases section.
Anyhow, here are the complete paragraphs.
Table 10.9 lists 8 differant glaciers; how much they have receeded
and the average rate of recession over various time periods.
The rates vary between 5 to 135 m/year.
Anyhow, it's just surprising that the Indians themselves have not
made the effort to perform a comprehensive study. As glaciers
melt back at an accelerated rate, the meltoff will cause rivers
to flow at a greater rate during the melt season.
So, maybe they are all content with the enhanced river flow.
Eventually there will come a turning point when the flow will diminish.
However, specific projections need to be based on extensive and
comprehensive data and not just a hand full of points.
