Ice, when heated, is supposed to melt.

That’s why a collection of glaciers in the Southeast Himalayas stymies those who know what they did 9,000 years ago. While most other Central Asian glaciers retreated under hotter summer temperatures, this group of glaciers advanced from one to six kilometers.
A new study by BYU geologist Summer Rupper pieces together the chain of events surrounding the unexpected glacial growth.
“Stronger monsoons were thought to be responsible,” said Rupper, who reports her findings in the September issue of the journal Quaternary Research. “Our research indicates the extra snowfall from monsoonal effects can only take credit for up to 30 percent of the glacial advance.”
As Central Asia’s summer climate warmed as much as 6 degrees Celsius, shifting weather patterns brought more clouds to the Southeast Himalayas. The additional shade created a pocket of cooler temperatures.
