A new study suggests that the glaciers in the Himalayas are shrinking, with different regions shrinking much faster than others.
The uncertainty of science: A new study suggests that the glaciers in the Himalayas are shrinking, with different regions shrinking much faster than others.
This study both supplements and contrasts other work which suggested that the western Himalayan glaciers were not shrinking.
It is interesting that the article above does not give any specifics on the rate of shrinkage, other than to say it is getting faster in some areas. Instead, the focus of this work centers more on the discovery that India’s monsoon winds have a significant influence on glacier growth or retreat.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The print edition can be purchased at Amazon. from any other book seller, or direct from my ebook publisher, ebookit.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

There are two key findings from the study:
1. Not only are the glaciers shrinking, they are shrinking rapidly. And as the author is quoted,
“Temperature rise is important.”
2. The contrasting with the previous study which showed glacier stability in one range, is due to the uncertainty of using GRACE satellites, which the study showing glacier stability used. This current study looked at the entire region (7100 glaciers), rather than one area.
And, as author Yao Tandong says,”… the GRACE satellites can only feel the gravitational pull and can’t tell the difference between ice and liquid water, they may have mistaken expanding glacial lakes for increases in glacier mass,”
And John Wahr, lead author of the GRACE study says, the criticism is valid.
By the way, the study itself provides the rate and amount of shrinkage.

The one quote of note is this:
“…(the Himalayas) shows the most extreme glacial shrinkage based on the reduction both of glacier length and area. The shrinkage is most pronounced in the southeastern TBP (region I), where the length decreased at a rate of 48.2 m yr.”
And “The smallest rate of glacier contraction is observed in the eastern Pamir regions (region V), with a retreat rate of 0.9 m yr.”
Other rates falling in between are listed as well.
And in regard to its general findings, here is the quote:
“IN ADDITION TO RISING TEMPERATURE, decreased precipitation in the Himalayas and increasing precipitation in the eastern Pamir accompanied by different atmospheric circulation patterns is probably driving these systematic differences.”
