It’s perhaps no surprise, once you read it. The sad surprise is that so many, even though all the leaves are falling, still proclaim “there is no autumn! It’s nothing but a hoax.”
“A decade or so ago, there were individual ponds on the Khumbu glacier but in the past five years or so they have begun to get larger and join up,” said Ann Rowan, who led the field study team from the universities of Sheffield and Leeds.
Dr Rowan’s team has been studying the behaviour of debris-covered glaciers, focusing on Khumbu.
“Particularly, on the left hand side of the lower reaches of the glacier, there is a series of about seven or eight large ponds that are now starting to link and form a big chain,” she told the BBC.
“There is water flowing from the upper part of the glacier through the series of these ponds and that is going to encourage them to join up.
“At present, the glacier appears to be disintegrating, and may form a few large and potentially hazardous lakes on the glacier surface.”
Not only are the lakes dangerous because of what they signal, but because of what they are becoming — soon large enough to blow through natural and artificial water controls and cause catastrophe to the human communities in the way.

And besides the glaciers, what is going on?
The combined average temperature over global land and ocean surfaces for September 2015 was the highest for September in the 136-year period of record, at 0.90°C (1.62°F) above the 20th century average of 15.0°C (59.0°F), surpassing the previous record set last year in 2014 by 0.12°C (0.19°F). This marks the fifth consecutive month a monthly high temperature record has been set and is the highest departure from average for any month among all 1629 months in the record that began in January 1880.
