Return to Nepal: Snow Sampling

Snow sampling along an unclimbed glacier near to Cho Oyu, the sixth highest peak in the world.

Editor’s Note: This is the third and final installment in a new series by Ulyana Horodyskyj, who chronicled an earlier expedition to Nepal in a series called, “Climbing Mount Everest,” which can be found by clicking here. Horodyskyj’s work focuses determining how airborne particles such as dust and soot that settle on massive glaciers alter [...]

Climbing Mount Everest: Black Soot on White Snow

Smog in the air, even at 17,000 feet, near Mount Everest base camp.

Editor’s Note: This is the fifth and final post in a series by geologist Ulyana Horodyskyj. She climbed several peaks in the Himalaya Mountains to try to determine how airborne particles such as dust and soot that settle on massive glaciers alter how snow and ice melt, which could affect climate change as well as [...]

Climbing Mount Everest: Risking Life and Limb for Science

The author and Jake St. Pierre on the Himlung icefall. Steep slopes and warming snow make climbing slow and dangerous.

Editor’s Note: This is the fourth post in a series by Ulyana Horodyskyj, a geologist who is trying to determine how airborne particles such as soot that settle on massive glaciers affect how fast the ice melts. In mid-April she and her team of scientists, volunteers and Sherpas were nearly at base camp on Mount [...]

Climbing Mount Everest: My Search for Dirty Snow

Editor’s note: This April, geologist and Ph.D. candidate Ulyana Horodyskyj will be climbing Mount Everest to determine how much soot is settling on snow at the top of mammoth glaciers, which could slow their growth at the top, even as they melt at much lower elevations. She will post updates to this blog as she [...]

Soot May Help Shift Tropics North

tropics

Soot may be responsible for the tropics expanding north, according to an analysis involving multiple computer models of the climate. By absorbing sunlight and trapping extra heat in the atmosphere, the tiny, black particles may be helping the poleward march of tropical conditions. The research will be published in Nature on May 17. (Scientific American [...]
