Ice sat down. That is now the cause of the Nepal-Tibet glacier collapse. I measured it myself.

A huge piece of ice fell from a high glacier into a river and the flood followed in Nepal and Tibet. Field teams mapped that fall in reports from Phys.org and the BBC. I did not climb the mountain. I stayed in the lab.

We froze twenty-six blocks on Tuesday and lined them on a steel counter. The control group was twenty-six cups of tap water left in the same room. The water did nothing. Each block of ice lowered itself, turned to a puddle, and spread toward the drain. The chance this happened by luck is very small. Scientists call that small chance a p-value. A p-value is a number that tells you luck is a weak story.

The glacier did not collapse. It sat down.

We have asked every remaining glacier to stay on its feet. None have answered.
